PCjs Machines

A collection of database management programs.  The mailing labels
program allows sorting by four fields and keying printing of labels by
any field.  PMB15.BAS provides a way of keeping track of events which
occur periodically such as bills, preventive maintenence items, dental
appointments, etc.  INDXCARD.BAS is intended to make it very easy to
create and maintain 3" by 5" card files.  By itself, it forms an
electronic typewriter with full editing facilities for the 3 by 5 card
format.  It can be used with the program PC- FILE III.

Features:

~ Forms an electronic typewriter with full editing facilities.
~ Uses PC-FILE to sort index cards prior to printing.
~ Sorts a mailing list by four fields.
~ Prints one across or two across labels.
~ Keeps track of bills, preventive maintenence items, dental
appointments.
~ Writes your appointments  or  activities for the whole year.
~ Schedules your activities from 6 a.m. till 10 p.m.
~ Creates a computerized Rolodex.

System Requirements:  Two disk drives, a Color/Graphics
Adapter Card (color not used), Epson MX-80 (or compatible) printer.

How to Start: Consult the .DOC files for documentation and
directions.  To run the BASIC programs follow the GETTING STARTED

        PLOTTER.DOC    Documentation for Plotter      4/19/86

            This  package  of programs contain  a  demonstration  program
        written  in  Turbo  Pascal  along with a set  of  procedures  for
        plotting  high resolution (640x400 pixel)  graphs.   The  plotter
        routines are intended for engineering and scientific applications
        where  X-Y  coordinate line plots are needed and  where  standard
        color graphic adaptor screen dumps are inadequate.   The routines
        are  simple  to use and provide a high resolution hard copy  from
        printers compatible with the Epson MX-80/FX-80 dot graphics.   It
        has  been tested on IBM PCs and ATs and a Radio Shack model 3000.
        I  have  not  tried it on any other  systems.   The  software  is
        composed of three files:

             o DEMOPLOT.PAS - A  pascal demonstration program which  uses
             the Pascal graphics procedures contained in HiResPlt.pas.

             o HiResPlt.PAS - A   file  of  Pascal  routines  which   are
             necessary to draw axis and perform plotting.  The procedures
             work in conjunction with another program,  HIPLOT2,  written
             in  assembly  code  which actually  performs  the  plotting.
             HiResPlt.pas  is used as an "include" file in programs  like
             DEMOPLOT which require graphics.

             o HIPLOT2.EXE - This  assembly code plotter attaches  itself
             to   the   system  as  a   run-and-remain-resident   program
             accessible via a single interrupt.  Access through interrupt
             was   chosen  to  simplify  interfacing  to   higher   level
             languages.  As a result, only the interface routines need to
             be customized to a particular compiler.

             o PLOTTER.DOC - This description of the plotter software.

        BACKGROUND:

             HIPLOT2   was  originally  written  to  provide   a   higher
        resolution  curve  than  was  available with  the  640x200  pixel
        resolution  of  an IBM Color  Graphics  Adapter  (CGA).   HIPLOT2
        "draws"  the plot into a large buffer to a resolution of  640x400
        pixels.   At  the  same  time,  it can optionally  draw  a  lower
        resolution  curve of 640x200 pixels on the CGA.   When a hardcopy
        is requested, the higher resolution curve is sent from the buffer
        to the printer in the Epson bit graphics format.   This is to  be
        contrasted  with a screen dump which has the same  resolution  as
        the display.

             Because   the  printed  resolution  is  different  from  the
        displayed  resolution,  the characters stored in the  buffer  and
        printed  on the hardcopy are selected from a different  character
        matrix  made  compatible with the higher  resolution.   The  CGA,
        however,  receives  the  lower resolution IBM ROM character  set.
        HIPLOT2 maps the character matrix to the CGA differently than  is
        done in other graphics packages like BASICA.   Mapping is done on


                                        1



        a  pixel boundary where the characters can be placed anywhere  on
        the CGA display.   In BASICA,  placement is restricted to column-
        row  boundarys.   Bit mapping provides flexibility when  labeling
        axis tics.

             Future  plans  include modifying HIPLOT2 to use  the  higher
        resolution  of  the IBM Enhanced Graphics Adapter (EGA) if  used,
        however  until  then,  the software uses the  highest  resolution
        available  on  the CGA.   It will work on the EGA  but  only  the
        reduced 640x200 resolution compatible with the CGA.  You may need
        to type "mode co80" before running the graphics software.  If you
        notice  loss  of  sync  when using a card other  than  the  color
        graphics  card,  you may need to reboot to avoid damage  to  your
        monitor.



             DEMOPLOT.PAS  is  a small demonstration program.   The  user
        should  try the demonstration program first to see how it  works.
        This  is done by first running HIPLOT2 to load the  machine  code
        plotter   into  memory  and  then  running  Turbo   Pascal   with
        DEMOPLOT.PAS as the work file.   Again, you may need to run "mode
        co80" before running Turbo if you use an EGA.

             The  demonstration  program first asks if a  color  graphics
        card is available.   If a no is given,  plotting to the screen is
        suppressed.   The  program then draws a diagonal line and a  box.
        It  then allows the user to position a crosshair using the cursor
        keys.   Absolute  coordinates  are displayed at the  top  of  the
        screen.  When the user presses <enter>, the program will ask if a
        hard  copy is desired.   A "y" followed by an <enter> will  cause
        the  program  to attempt to send the plot to  the  printer.   Any
        other character or simply an <enter> will cause the program to go
        to the next demonstration.

             The  next  demonstration  is a more realistic  plot  of  the
        absolute  value of a sine wave followed by a simple dotted  line.
        Again,  the  user  is  given  the opportunity  to  read  out  the
        coordinates of the curve with a crosshair and then to get a  hard
        copy of the curve.   To simply view the operation of the plotter,
        simply  keep hitting <enter> and the demonstration will  progress
        from beginning to end.

             If you have the same hardware configuration as I, you should
        have no problem running the program.  I do not have the resources
        to  try  the software on any more than a few systems so I  cannot
        say  what will or will not work.   The two systems which  I  have
        been able to use the software on are:

        Configuration:      1                        2
        Type:               IBM PC, 256k main board  IBM AT
        Graphics board:     IBM CGA                  IBM EGA
        Disc Drives:        2ea. Teac DSDD Floppies  20 Mbyte hard disc
        Total RAM:          640k                     512k
        IBM DOS version:    2.0                      3.10

             It also seems to run on a Radio Shack model 3000.


             The  only  difference  between the operation  on  the  above
        systems  involves  the  timing used to fast move  the  crosshair.
        Look in the source code and set the value of a constant  MinCount
        in  procedure Crosshair.   Correctly setting it is not  mandatory
        but  it  removes the jerkyness that might otherwise exist of  the
        value is not set for your system.

             There  are several reasons why the software may not work  on
        your  system.   First,  of course,  is that you may have  a  very
        different display board than I do.  The software will try to plot
        points  using interrupt 10h.   If your graphics adapter  modifies
        this  interrupt  routine,  the  results  will  be  unpredictable.
        Secondly,  HIPLOT2  will  try  to attach a pointer to  itself  at
        interrupt  64h.   If you already have something attached to  that
        interrupt, the software will give you an error message and abort.
        Some hard disk software configurations,  for instance, may attach
        their  software to the same pointer,  so  be  careful.

             Finally,  there  have been reports of damage to monitors  if
        they are driven by the wrong sync.   Since this software does not
        address  the  hardware  directly,  there should  be  no  problem.
        HiResPlt  uses  the Turbo graphics procedures and  HIPLOT2  plots
        points  via interrupt 10H,  therefore there should be no problem.
        If you use a different display adaptor,  you should verify that a
        sync error will not occur.

          Because  of the wide variety of configurations,  the  following
        disclaimer is necessary:

                      DESCRIPTION OF PROCEDURES IN HiResPlt

             The  plotter procedures and functions described next are all
        part of the plotter package.   The demonstration program does not
        have any procedures or functions unique to it alone.


        Hcmd(CMD,I1,I2:integer)

             This  and  Htext perform the actual interrupts  to  HIPLOT2.
        Hcmd has three arguments.   CMD is a command integer which  tells
        HIPLOT2 what you want it to do.   I1 and I2,  also integers,  are
        the parameters which may be required.  When coordinates are to be
        specified, I1 represents X and I2 represents Y.

        Command   Function
             0    Set origin (cursor) of next curve to point I1,I2
             1    Plot line from last point (origin) to I1,I2
             2    Not used from Hcmd.  See Htext
             3    Clear plotter buffer and, if selected, the CRT screen
             4    Make hardcopy on Epson MX-80 or equivalent printer
             5    Home cursor to x=0, y=0.
             6    Set mode bits to least significant byte of I1
             7    Set line pattern to pattern in I1
             8    Set pixel "color". I1=0 for white (Erase), I1=1 for
                  black (default).  Used to erase curve.
             9    Do not use
             10   Do not use
             11   Set x window to I1 and I2   (I2 > I1)  Prevents
                  plotting outside of window.
             12   Set y window to I1 and I2   (I2 > I1)  Prevents
                  plotting outside of window.
             13   Do not use



        Htext(CMD:Integer, S:String, I:Integer)-

             This  is  similar  to Hcmd except it is  intended  for  text
        command  2 where S is the string to be placed on the graph at the
        cursor location and I is the maximum length.   The string printed
        will be the lesser of the length of the string or I.


        Hdraw(IX1,IY1,IX2,IY2)-

             This draws a line from IX1,  IY1 to IX2, IY2 in the non-axis
        mode.  It is similar to Plot except it uses absolute co-ordinates
        and does not draw from the last point.


        Pattern(I:Integer)-



                                        4



             This sets the line pattern to reflect the bit pattern of the
        integer,  I.   If used,  it must be placed after Axis or SetPlot.
        Note   that   Pattern($FFFF)   will  make  a   solid   line   and
        Pattern($CCCC)  will  produce  a dotted line with  medium  length
        dots.


        ScreenOn  and ScreenOff-

             These  procedures  enable or disable plotting  to  the  CRT.
        Normally,  ScreenOn would be used unless the system does not have
        an  IBM  color  graphic adapter such as the CGA or  the  EGA,  or
        something equivalent.



        ToUpper(S:String)-   This simply converts string S to upper case.


        Beep-                This just makes a short beep near middle C.


        Alarm-               This produces a more noticeable tone



        SetOption(B:Byte)-

             HIPLOT2  has a set of 8 flags which select  options.   These
        are only useful to other procedures.  If interested, refer to the
        comments in the routine.



        Option(I:Integer, B:Boolean)-

             The  same comments as for SetOption.   This just allows  the
        individual setting of the bits.


        BW80-
             This resets the CRT back to text mode after a plot.


        Cls-
             This  clears  the screen.   It has no effect on the  plotter
        buffer.  Clearing the buffer is done with Hcmd using command 3.


        Box(IX1,IY1,IX2,IY2)-

             This will draw a box with the main diagonal from IX1, IY1 to
        IX2, IY2.




                                        5



        FindReal(IX,IY:Integer, Xval,Yval:Real)-

             This converts the integer absolute screen values to the real
        values computed by Axis.  It is not used in non-axis plotting.


        SetCross(IX,IY:Integer)-

             A utility routine for placing a crosshair on the plot.  User
        does not need to use this directly.  It is called by Crosshair.


        DaTime(I:Integer)-

             This  places  the date and the time at the  left  and  right
        sides  of the plot.   It is invoked in Axis so you do not need it
        unless you plan to use SetPlot instead.   I=0 places them at  the
        bottom, I=1 places them at the top.


        SetTypeComputer(I1,I2: Integer)-

             This  sets  the timing in the crosshair updating routine  to
        match  the type of computer used.   This routine allows low  rate
        keypresses  to  move  the  crosshair  in  small  steps  and  fast
        keypresses  to  move the crosshair in large  steps.   It  is  not
        required  to invoke this routine,  but it makes the operation  of
        the crosshair appear smoother.


        Crosshair(Ix,Iy:Integer)-

             This draws a crosshair on either an axis or a non-axis  plot
        and  allows the user to read out the values into the integers Ix,
        Iy.   In the axis mode,  Ix, Iy should be converted to real graph
        values by using FindReal.


        Hcopy(Str1,Str2:string)-

             If  Str1 is the string "PAUSE",  the routine will ask  if  a
        hardcopy  is desired.   Without it,  a hardcopy is  automatically
        made.  If Str2 is the string "EJECT", then a page will be ejected
        after plotting.

        Vcheck-

             This  is  a  function  which checks to see  if  the  HIPLOT2
        software is loaded.   If it is not,  Vcheck will be set to 0 else
        Vcheck  will be set equal the current HIPLOT2 version  number  if
        HIPLOT2 is loaded.



        FmtNum(Val:real)-


                                        6




             This is used by Axis to place a formatted number on the plot
        at the current cursor position.



        Xinit-     This is used by Axis to initialize the plotter.



        SetPlot-

             This  initializes  the plotter for subsequent  plotting  for
        cases where line drawings alone are desired (non-axis  plotting).
        The  global  scale factors are set to create a screen where  x=0,
        y=0  represents the upper left part of the screen as  in  Turbo's
        Plot.   The lower right co-ordinates are x=639, y=399.  Note that
        the  vertical  resolution is twice that of Turbo.   This  routine
        takes  the  place  of  Axis.   Either  use  SetPlot  or  Axis  to
        initialize the plotter.



        Axis(X1,X2,X3,Y1,Y2,Y3:Real)-

             This initializes the CRT and plotter buffer,  draws the axis
        and  sets the required scale factors for later plotting.   For  a
        linear X-axis,  X1 is the start value,  X2 is the stop value, and
        X3  is  the incremental value to be added at  each  tic.   For  a
        Logarithmic X-axis,  X1 is the starting decade,  x2 is the number
        of decades and x3=0.  The same is true for the Y axis.   When the
        axis is drawn, if the values to be printed require an exponential
        format,  they  are  scaled with the multiplication factor  placed
        close by in a box near the axis.   Not included in the  parameter
        list  but used as a global variable is Alpha[n],  where n  ranges
        from 1 to 9.   These are the strings to be printed.   Alpha[1] is
        the x-axis label,  Alpha[2] is the Y-axis label and the remainder
        constitute the heading.



        ReOrg-

             This  resets  the origin flag so that the next point  to  be
        plotted will become the starting point for the next curve.   This
        allows  multiple curves to be plotted.   This is used only in the
        axis plotting mode.



        Interpolate(Var I1,I2: Integer;  I3,I4: Integer)-

             When  a program asks the plotter to plot out of  the  active
        window, the plotter will stop plotting at the boundarys.  HIPLOT2
        simply   stops  placing  pixels  but  acts  as  if  the  plot  is


                                        7



        continuing.   Because only integers are passed to HIPLOT2,  it is
        possible for overflow to place the point at the other side of the
        active   window.    Interpolate   helps   calculate   the   point
        corresponding  to  the edge of the window to allow  limiting  the
        line drawn to the boundary to avoid the problem.   The routine is
        intended for internal use only.

        Hplot(X,Y:real)-

             The  values  of  X,Y are plotted after  being  scaled.   The
        scaling  is based on the values selected by the user in the  call
        to Axis.   There is no separate windowing or whatever as in  more
        sophisticated  plotter packages.   This is used only in the  axis
        mode.  For non-axis mode, use Hdraw.



        Insert(X,Y:Real, I:Integer)-

             This places the single digit integer,  I,  at a location  on
        the plot specified by X and Y.   X and Y are real quantities.   I
        ranges from 1 through 9.



        FINAL COMMENTS:

             That's  it.   The plotter package is meant to be easy to use
        at the expense of some flexibility.  This is the first version to
        be  released although I have used various versions in my own work
        for several years in Turbo-Pascal,  FORTRAN and BASIC.   I  would
        like  to  revisit this software in detail in a few months  and  I
        would  appreciate  any comments and suggested  modifications.   I
        have not released the source for HIPLOT2 yet since I plan to make
        some significant changes.  One of these may be a search algorithm
        to  place the routine at an available interrupt in case  the  one
        currently used has already been taken.   Another will be to allow
        drawing a high resolution curve on the enhanced graphics adapter.
        Please send comments and  suggestions  to  me.   Please  describe
        your  machine.    I  would  like to know if there are clones that
        have  problems  with this software.

                          A Final Note:

Cursor speed constant:

       The demonstration program was modified to allow direct
entry of MinCount99 which sets the minimum count between any two
keypresses of the same cursor control arrow.  This discriminates
between two finger taps and holding the key down.  The latter
means to move the cursor in bigger steps.  Unfortunately, this
test makes the software processor speed sensitive.

       In retrospect, I should have calculated time using the
system clock rather than relying on processor speed because of
the wide variety of machines in the world.  Alas, its too late
now.   That will be left for the next version when I add mouse
software.

       DEMOPLOT was modified at the last moment to allow you to
select the value for the speed constant.  If my suggestions do
not work best for your machine, try doubling the constant by a
factor of 2 to move the cursor quickly when the key is held down.
Reduce the constant by a factor by 2 to allow the cursor to move
in small steps on individual key presses.  You can fine tune the
value if you want.  The number is typed as a constant.



NEW HIPLOT2:
    The current HIPLOT2 version is 10-08-86 8:40PM and it replaces
    the version 2-23-86  12:08PM.  The only difference is to modify
    hardcopy routine for faster output.  It now uses INT 17h rather
    than the much slower INT 21h.


OLD WARNING MESSAGE:
    The documentation has a stiff warning to make the user pay
    attention when he first tries it on his system.  After using
    the software on a number of clones, it appears that the worst
    thing that should happen is that HIPLOT2 will not load.  It looks
    to see if the interrupt is occupied before installing itself.
    If the vector is 0000:0000 then it assumes it to be available.
    If not, it says that 64h is occupied and returns you to the
    system.   The Pascal procedures have a function Vcheck which
    looks for the 16 bit sequence A55Ah and a valid version number.
    To keep the plotting routines as fast as possible, the check is
    done only once.  If something changes the vector during a plot
    than there could be a problem.  Just make sure to include
    Vcheck in your software and avoid changing int 64h during a plot.


COMPATIBILITIES:
    I have found the software to work on:
    o IBM PC
    o IBM XT
    o IBM AT
    o PC Limited 8 Mhz AT
    o Wells American 8 Mhz
    o Wells American 10 Mhz
    o Lanier C-2400 AT
    o Radio Shack 3000

    I have not kept a list of printers that it works on but I know
    it has worked on a good number.  The only printer that did not work
    well with it was a Star Radix-15 which does not work with 123
    graphs either for the same reason.  The bit mapped graphics are
    8 pixels high and a line feed should skip 8 pixels worth.  The
    Star skips more and leaves a gap.   Just my luck that the printer
    happens to belong to my fiance'.

INCOMPATIBILITIES:
    o Some network software use the same interrupt vector and Hiplot2
    will not allow loading.  If you network, try not installing the
    network software prior to plotting to your printer.

    o As I said, the Star Radix-15 skips lines.

        PLOTTER.DOC    Documentation for Plotter      4/19/86

            This  package  of programs contain  a  demonstration  program
        written  in  Turbo  Pascal  along with a set  of  procedures  for
        plotting  high resolution (640x400 pixel)  graphs.   The  plotter
        routines are intended for engineering and scientific applications
        where  X-Y  coordinate line plots are needed and  where  standard
        color graphic adaptor screen dumps are inadequate.   The routines
        are  simple  to use and provide a high resolution hard copy  from
        printers compatible with the Epson MX-80/FX-80 dot graphics.   It
        has  been tested on IBM PCs and ATs and a Radio Shack model 3000.
        I  have  not  tried it on any other  systems.   The  software  is
        composed of three files:

             o DEMOPLOT.PAS - A  pascal demonstration program which  uses
             the Pascal graphics procedures contained in HiResPlt.pas.

             o HiResPlt.PAS - A   file  of  Pascal  routines  which   are
             necessary to draw axis and perform plotting.  The procedures
             work in conjunction with another program,  HIPLOT2,  written
             in  assembly  code  which actually  performs  the  plotting.
             HiResPlt.pas  is used as an "include" file in programs  like
             DEMOPLOT which require graphics.

             o HIPLOT2.EXE - This  assembly code plotter attaches  itself
             to   the   system  as  a   run-and-remain-resident   program
             accessible via a single interrupt.  Access through interrupt
             was   chosen  to  simplify  interfacing  to   higher   level
             languages.  As a result, only the interface routines need to
             be customized to a particular compiler.

             o PLOTTER.DOC - This description of the plotter software.

        BACKGROUND:

             HIPLOT2   was  originally  written  to  provide   a   higher
        resolution  curve  than  was  available with  the  640x200  pixel
        resolution  of  an IBM Color  Graphics  Adapter  (CGA).   HIPLOT2
        "draws"  the plot into a large buffer to a resolution of  640x400
        pixels.   At  the  same  time,  it can optionally  draw  a  lower
        resolution  curve of 640x200 pixels on the CGA.   When a hardcopy
        is requested, the higher resolution curve is sent from the buffer
        to the printer in the Epson bit graphics format.   This is to  be
        contrasted  with a screen dump which has the same  resolution  as
        the display.

             Because   the  printed  resolution  is  different  from  the
        displayed  resolution,  the characters stored in the  buffer  and
        printed  on the hardcopy are selected from a different  character
        matrix  made  compatible with the higher  resolution.   The  CGA,
        however,  receives  the  lower resolution IBM ROM character  set.
        HIPLOT2 maps the character matrix to the CGA differently than  is
        done in other graphics packages like BASICA.   Mapping is done on


                                        1



        a  pixel boundary where the characters can be placed anywhere  on
        the CGA display.   In BASICA,  placement is restricted to column-
        row  boundarys.   Bit mapping provides flexibility when  labeling
        axis tics.

             Future  plans  include modifying HIPLOT2 to use  the  higher
        resolution  of  the IBM Enhanced Graphics Adapter (EGA) if  used,
        however  until  then,  the software uses the  highest  resolution
        available  on  the CGA.   It will work on the EGA  but  only  the
        reduced 640x200 resolution compatible with the CGA.  You may need
        to type "mode co80" before running the graphics software.  If you
        notice  loss  of  sync  when using a card other  than  the  color
        graphics  card,  you may need to reboot to avoid damage  to  your
        monitor.



             DEMOPLOT.PAS  is  a small demonstration program.   The  user
        should  try the demonstration program first to see how it  works.
        This  is done by first running HIPLOT2 to load the  machine  code
        plotter   into  memory  and  then  running  Turbo   Pascal   with
        DEMOPLOT.PAS as the work file.   Again, you may need to run "mode
        co80" before running Turbo if you use an EGA.

             The  demonstration  program first asks if a  color  graphics
        card is available.   If a no is given,  plotting to the screen is
        suppressed.   The  program then draws a diagonal line and a  box.
        It  then allows the user to position a crosshair using the cursor
        keys.   Absolute  coordinates  are displayed at the  top  of  the
        screen.  When the user presses <enter>, the program will ask if a
        hard  copy is desired.   A "y" followed by an <enter> will  cause
        the  program  to attempt to send the plot to  the  printer.   Any
        other character or simply an <enter> will cause the program to go
        to the next demonstration.

             The  next  demonstration  is a more realistic  plot  of  the
        absolute  value of a sine wave followed by a simple dotted  line.
        Again,  the  user  is  given  the opportunity  to  read  out  the
        coordinates of the curve with a crosshair and then to get a  hard
        copy of the curve.   To simply view the operation of the plotter,
        simply  keep hitting <enter> and the demonstration will  progress
        from beginning to end.

             If you have the same hardware configuration as I, you should
        have no problem running the program.  I do not have the resources
        to  try  the software on any more than a few systems so I  cannot
        say  what will or will not work.   The two systems which  I  have
        been able to use the software on are:

        Configuration:      1                        2
        Type:               IBM PC, 256k main board  IBM AT
        Graphics board:     IBM CGA                  IBM EGA
        Disc Drives:        2ea. Teac DSDD Floppies  20 Mbyte hard disc
        Total RAM:          640k                     512k
        IBM DOS version:    2.0                      3.10

             It also seems to run on a Radio Shack model 3000.


             The  only  difference  between the operation  on  the  above
        systems  involves  the  timing used to fast move  the  crosshair.
        Look in the source code and set the value of a constant  MinCount
        in  procedure Crosshair.   Correctly setting it is not  mandatory
        but  it  removes the jerkyness that might otherwise exist of  the
        value is not set for your system.

             There  are several reasons why the software may not work  on
        your  system.   First,  of course,  is that you may have  a  very
        different display board than I do.  The software will try to plot
        points  using interrupt 10h.   If your graphics adapter  modifies
        this  interrupt  routine,  the  results  will  be  unpredictable.
        Secondly,  HIPLOT2  will  try  to attach a pointer to  itself  at
        interrupt  64h.   If you already have something attached to  that
        interrupt, the software will give you an error message and abort.
        Some hard disk software configurations,  for instance, may attach
        their  software to the same pointer,  so  be  careful.

             Finally,  there  have been reports of damage to monitors  if
        they are driven by the wrong sync.   Since this software does not
        address  the  hardware  directly,  there should  be  no  problem.
        HiResPlt  uses  the Turbo graphics procedures and  HIPLOT2  plots
        points  via interrupt 10H,  therefore there should be no problem.
        If you use a different display adaptor,  you should verify that a
        sync error will not occur.

          Because  of the wide variety of configurations,  the  following
        disclaimer is necessary:


        DISCLAIMER:
             This  software is provided free for public domain on an  "as
        is"  basis for others to use on a non-profit basis.   The  Author

        advised of the possibility of such damages.

                      DESCRIPTION OF PROCEDURES IN HiResPlt

             The  plotter procedures and functions described next are all
        part of the plotter package.   The demonstration program does not
        have any procedures or functions unique to it alone.


        Hcmd(CMD,I1,I2:integer)

             This  and  Htext perform the actual interrupts  to  HIPLOT2.
        Hcmd has three arguments.   CMD is a command integer which  tells
        HIPLOT2 what you want it to do.   I1 and I2,  also integers,  are
        the parameters which may be required.  When coordinates are to be
        specified, I1 represents X and I2 represents Y.

        Command   Function
             0    Set origin (cursor) of next curve to point I1,I2
             1    Plot line from last point (origin) to I1,I2
             2    Not used from Hcmd.  See Htext
             3    Clear plotter buffer and, if selected, the CRT screen
             4    Make hardcopy on Epson MX-80 or equivalent printer
             5    Home cursor to x=0, y=0.
             6    Set mode bits to least significant byte of I1
             7    Set line pattern to pattern in I1
             8    Set pixel "color". I1=0 for white (Erase), I1=1 for
                  black (default).  Used to erase curve.
             9    Do not use
             10   Do not use
             11   Set x window to I1 and I2   (I2 > I1)  Prevents
                  plotting outside of window.
             12   Set y window to I1 and I2   (I2 > I1)  Prevents
                  plotting outside of window.
             13   Do not use



        Htext(CMD:Integer, S:String, I:Integer)-

             This  is  similar  to Hcmd except it is  intended  for  text
        command  2 where S is the string to be placed on the graph at the
        cursor location and I is the maximum length.   The string printed
        will be the lesser of the length of the string or I.


        Hdraw(IX1,IY1,IX2,IY2)-

             This draws a line from IX1,  IY1 to IX2, IY2 in the non-axis
        mode.  It is similar to Plot except it uses absolute co-ordinates
        and does not draw from the last point.


        Pattern(I:Integer)-



                                        4



             This sets the line pattern to reflect the bit pattern of the
        integer,  I.   If used,  it must be placed after Axis or SetPlot.
        Note   that   Pattern($FFFF)   will  make  a   solid   line   and
        Pattern($CCCC)  will  produce  a dotted line with  medium  length
        dots.


        ScreenOn  and ScreenOff-

             These  procedures  enable or disable plotting  to  the  CRT.
        Normally,  ScreenOn would be used unless the system does not have
        an  IBM  color  graphic adapter such as the CGA or  the  EGA,  or
        something equivalent.



        ToUpper(S:String)-   This simply converts string S to upper case.


        Beep-                This just makes a short beep near middle C.


        Alarm-               This produces a more noticeable tone



        SetOption(B:Byte)-

             HIPLOT2  has a set of 8 flags which select  options.   These
        are only useful to other procedures.  If interested, refer to the
        comments in the routine.



        Option(I:Integer, B:Boolean)-

             The  same comments as for SetOption.   This just allows  the
        individual setting of the bits.


        BW80-
             This resets the CRT back to text mode after a plot.


        Cls-
             This  clears  the screen.   It has no effect on the  plotter
        buffer.  Clearing the buffer is done with Hcmd using command 3.


        Box(IX1,IY1,IX2,IY2)-

             This will draw a box with the main diagonal from IX1, IY1 to
        IX2, IY2.




                                        5



        FindReal(IX,IY:Integer, Xval,Yval:Real)-

             This converts the integer absolute screen values to the real
        values computed by Axis.  It is not used in non-axis plotting.


        SetCross(IX,IY:Integer)-

             A utility routine for placing a crosshair on the plot.  User
        does not need to use this directly.  It is called by Crosshair.


        DaTime(I:Integer)-

             This  places  the date and the time at the  left  and  right
        sides  of the plot.   It is invoked in Axis so you do not need it
        unless you plan to use SetPlot instead.   I=0 places them at  the
        bottom, I=1 places them at the top.


        SetTypeComputer(I1,I2: Integer)-

             This  sets  the timing in the crosshair updating routine  to
        match  the type of computer used.   This routine allows low  rate
        keypresses  to  move  the  crosshair  in  small  steps  and  fast
        keypresses  to  move the crosshair in large  steps.   It  is  not
        required  to invoke this routine,  but it makes the operation  of
        the crosshair appear smoother.


        Crosshair(Ix,Iy:Integer)-

             This draws a crosshair on either an axis or a non-axis  plot
        and  allows the user to read out the values into the integers Ix,
        Iy.   In the axis mode,  Ix, Iy should be converted to real graph
        values by using FindReal.


        Hcopy(Str1,Str2:string)-

             If  Str1 is the string "PAUSE",  the routine will ask  if  a
        hardcopy  is desired.   Without it,  a hardcopy is  automatically
        made.  If Str2 is the string "EJECT", then a page will be ejected
        after plotting.

        Vcheck-

             This  is  a  function  which checks to see  if  the  HIPLOT2
        software is loaded.   If it is not,  Vcheck will be set to 0 else
        Vcheck  will be set equal the current HIPLOT2 version  number  if
        HIPLOT2 is loaded.



        FmtNum(Val:real)-


                                        6




             This is used by Axis to place a formatted number on the plot
        at the current cursor position.



        Xinit-     This is used by Axis to initialize the plotter.



        SetPlot-

             This  initializes  the plotter for subsequent  plotting  for
        cases where line drawings alone are desired (non-axis  plotting).
        The  global  scale factors are set to create a screen where  x=0,
        y=0  represents the upper left part of the screen as  in  Turbo's
        Plot.   The lower right co-ordinates are x=639, y=399.  Note that
        the  vertical  resolution is twice that of Turbo.   This  routine
        takes  the  place  of  Axis.   Either  use  SetPlot  or  Axis  to
        initialize the plotter.



        Axis(X1,X2,X3,Y1,Y2,Y3:Real)-

             This initializes the CRT and plotter buffer,  draws the axis
        and  sets the required scale factors for later plotting.   For  a
        linear X-axis,  X1 is the start value,  X2 is the stop value, and
        X3  is  the incremental value to be added at  each  tic.   For  a
        Logarithmic X-axis,  X1 is the starting decade,  x2 is the number
        of decades and x3=0.  The same is true for the Y axis.   When the
        axis is drawn, if the values to be printed require an exponential
        format,  they  are  scaled with the multiplication factor  placed
        close by in a box near the axis.   Not included in the  parameter
        list  but used as a global variable is Alpha[n],  where n  ranges
        from 1 to 9.   These are the strings to be printed.   Alpha[1] is
        the x-axis label,  Alpha[2] is the Y-axis label and the remainder
        constitute the heading.



        ReOrg-

             This  resets  the origin flag so that the next point  to  be
        plotted will become the starting point for the next curve.   This
        allows  multiple curves to be plotted.   This is used only in the
        axis plotting mode.



        Interpolate(Var I1,I2: Integer;  I3,I4: Integer)-

             When  a program asks the plotter to plot out of  the  active
        window, the plotter will stop plotting at the boundarys.  HIPLOT2
        simply   stops  placing  pixels  but  acts  as  if  the  plot  is


                                        7



        continuing.   Because only integers are passed to HIPLOT2,  it is
        possible for overflow to place the point at the other side of the
        active   window.    Interpolate   helps   calculate   the   point
        corresponding  to  the edge of the window to allow  limiting  the
        line drawn to the boundary to avoid the problem.   The routine is
        intended for internal use only.

        Hplot(X,Y:real)-

             The  values  of  X,Y are plotted after  being  scaled.   The
        scaling  is based on the values selected by the user in the  call
        to Axis.   There is no separate windowing or whatever as in  more
        sophisticated  plotter packages.   This is used only in the  axis
        mode.  For non-axis mode, use Hdraw.



        Insert(X,Y:Real, I:Integer)-

             This places the single digit integer,  I,  at a location  on
        the plot specified by X and Y.   X and Y are real quantities.   I
        ranges from 1 through 9.



        FINAL COMMENTS:

             That's  it.   The plotter package is meant to be easy to use
        at the expense of some flexibility.  This is the first version to
        be  released although I have used various versions in my own work
        for several years in Turbo-Pascal,  FORTRAN and BASIC.   I  would
        like  to  revisit this software in detail in a few months  and  I
        would  appreciate  any comments and suggested  modifications.   I
        have not released the source for HIPLOT2 yet since I plan to make
        some significant changes.  One of these may be a search algorithm
        to  place the routine at an available interrupt in case  the  one
        currently used has already been taken.   Another will be to allow
        drawing a high resolution curve on the enhanced graphics adapter.
        Please send comments and  suggestions  to  me.   Please  describe
        your  machine.    I  would  like to know if there are clones that
        have  problems  with this software.

                          A Final Note:

Cursor speed constant:

       The demonstration program was modified to allow direct
entry of MinCount99 which sets the minimum count between any two
keypresses of the same cursor control arrow.  This discriminates
between two finger taps and holding the key down.  The latter
means to move the cursor in bigger steps.  Unfortunately, this
test makes the software processor speed sensitive.

       In retrospect, I should have calculated time using the
system clock rather than relying on processor speed because of
the wide variety of machines in the world.  Alas, its too late
now.   That will be left for the next version when I add mouse
software.

       DEMOPLOT was modified at the last moment to allow you to
select the value for the speed constant.  If my suggestions do
not work best for your machine, try doubling the constant by a
factor of 2 to move the cursor quickly when the key is held down.
Reduce the constant by a factor by 2 to allow the cursor to move
in small steps on individual key presses.  You can fine tune the
value if you want.  The number is typed as a constant.



NEW HIPLOT2:
    The current HIPLOT2 version is 10-08-86 8:40PM and it replaces
    the version 2-23-86  12:08PM.  The only difference is to modify
    hardcopy routine for faster output.  It now uses INT 17h rather
    than the much slower INT 21h.


OLD WARNING MESSAGE:
    The documentation has a stiff warning to make the user pay
    attention when he first tries it on his system.  After using
    the software on a number of clones, it appears that the worst
    thing that should happen is that HIPLOT2 will not load.  It looks
    to see if the interrupt is occupied before installing itself.
    If the vector is 0000:0000 then it assumes it to be available.
    If not, it says that 64h is occupied and returns you to the
    system.   The Pascal procedures have a function Vcheck which
    looks for the 16 bit sequence A55Ah and a valid version number.
    To keep the plotting routines as fast as possible, the check is
    done only once.  If something changes the vector during a plot
    than there could be a problem.  Just make sure to include
    Vcheck in your software and avoid changing int 64h during a plot.


COMPATIBILITIES:
    I have found the software to work on:
    o IBM PC
    o IBM XT
    o IBM AT
    o PC Limited 8 Mhz AT
    o Wells American 8 Mhz
    o Wells American 10 Mhz
    o Lanier C-2400 AT
    o Radio Shack 3000

    I have not kept a list of printers that it works on but I know
    it has worked on a good number.  The only printer that did not work
    well with it was a Star Radix-15 which does not work with 123
    graphs either for the same reason.  The bit mapped graphics are
    8 pixels high and a line feed should skip 8 pixels worth.  The
    Star skips more and leaves a gap.   Just my luck that the printer
    happens to belong to my fiance'.

INCOMPATIBILITIES:
    o Some network software use the same interrupt vector and Hiplot2
    will not allow loading.  If you network, try not installing the
    network software prior to plotting to your printer.

    o As I said, the Star Radix-15 skips lines.

        PLOTTER.DOC    Documentation for Plotter      4/19/86

            This  package  of programs contain  a  demonstration  program
        written  in  Turbo  Pascal  along with a set  of  procedures  for
        plotting  high resolution (640x400 pixel)  graphs.   The  plotter
        routines are intended for engineering and scientific applications
        where  X-Y  coordinate line plots are needed and  where  standard
        color graphic adaptor screen dumps are inadequate.   The routines
        are  simple  to use and provide a high resolution hard copy  from
        printers compatible with the Epson MX-80/FX-80 dot graphics.   It
        has  been tested on IBM PCs and ATs and a Radio Shack model 3000.
        I  have  not  tried it on any other  systems.   The  software  is
        composed of three files:

             o DEMOPLOT.PAS - A  pascal demonstration program which  uses
             the Pascal graphics procedures contained in HiResPlt.pas.

             o HiResPlt.PAS - A   file  of  Pascal  routines  which   are
             necessary to draw axis and perform plotting.  The procedures
             work in conjunction with another program,  HIPLOT2,  written
             in  assembly  code  which actually  performs  the  plotting.
             HiResPlt.pas  is used as an "include" file in programs  like
             DEMOPLOT which require graphics.

             o HIPLOT2.EXE - This  assembly code plotter attaches  itself
             to   the   system  as  a   run-and-remain-resident   program
             accessible via a single interrupt.  Access through interrupt
             was   chosen  to  simplify  interfacing  to   higher   level
             languages.  As a result, only the interface routines need to
             be customized to a particular compiler.

             o PLOTTER.DOC - This description of the plotter software.

        BACKGROUND:

             HIPLOT2   was  originally  written  to  provide   a   higher
        resolution  curve  than  was  available with  the  640x200  pixel
        resolution  of  an IBM Color  Graphics  Adapter  (CGA).   HIPLOT2
        "draws"  the plot into a large buffer to a resolution of  640x400
        pixels.   At  the  same  time,  it can optionally  draw  a  lower
        resolution  curve of 640x200 pixels on the CGA.   When a hardcopy
        is requested, the higher resolution curve is sent from the buffer
        to the printer in the Epson bit graphics format.   This is to  be
        contrasted  with a screen dump which has the same  resolution  as
        the display.

             Because   the  printed  resolution  is  different  from  the
        displayed  resolution,  the characters stored in the  buffer  and
        printed  on the hardcopy are selected from a different  character
        matrix  made  compatible with the higher  resolution.   The  CGA,
        however,  receives  the  lower resolution IBM ROM character  set.
        HIPLOT2 maps the character matrix to the CGA differently than  is
        done in other graphics packages like BASICA.   Mapping is done on


                                        1



        a  pixel boundary where the characters can be placed anywhere  on
        the CGA display.   In BASICA,  placement is restricted to column-
        row  boundarys.   Bit mapping provides flexibility when  labeling
        axis tics.

             Future  plans  include modifying HIPLOT2 to use  the  higher
        resolution  of  the IBM Enhanced Graphics Adapter (EGA) if  used,
        however  until  then,  the software uses the  highest  resolution
        available  on  the CGA.   It will work on the EGA  but  only  the
        reduced 640x200 resolution compatible with the CGA.  You may need
        to type "mode co80" before running the graphics software.  If you
        notice  loss  of  sync  when using a card other  than  the  color
        graphics  card,  you may need to reboot to avoid damage  to  your
        monitor.



             DEMOPLOT.PAS  is  a small demonstration program.   The  user
        should  try the demonstration program first to see how it  works.
        This  is done by first running HIPLOT2 to load the  machine  code
        plotter   into  memory  and  then  running  Turbo   Pascal   with
        DEMOPLOT.PAS as the work file.   Again, you may need to run "mode
        co80" before running Turbo if you use an EGA.

             The  demonstration  program first asks if a  color  graphics
        card is available.   If a no is given,  plotting to the screen is
        suppressed.   The  program then draws a diagonal line and a  box.
        It  then allows the user to position a crosshair using the cursor
        keys.   Absolute  coordinates  are displayed at the  top  of  the
        screen.  When the user presses <enter>, the program will ask if a
        hard  copy is desired.   A "y" followed by an <enter> will  cause
        the  program  to attempt to send the plot to  the  printer.   Any
        other character or simply an <enter> will cause the program to go
        to the next demonstration.

             The  next  demonstration  is a more realistic  plot  of  the
        absolute  value of a sine wave followed by a simple dotted  line.
        Again,  the  user  is  given  the opportunity  to  read  out  the
        coordinates of the curve with a crosshair and then to get a  hard
        copy of the curve.   To simply view the operation of the plotter,
        simply  keep hitting <enter> and the demonstration will  progress
        from beginning to end.

             If you have the same hardware configuration as I, you should
        have no problem running the program.  I do not have the resources
        to  try  the software on any more than a few systems so I  cannot
        say  what will or will not work.   The two systems which  I  have
        been able to use the software on are:

        Configuration:      1                        2
        Type:               IBM PC, 256k main board  IBM AT
        Graphics board:     IBM CGA                  IBM EGA
        Disc Drives:        2ea. Teac DSDD Floppies  20 Mbyte hard disc
        Total RAM:          640k                     512k
        IBM DOS version:    2.0                      3.10

             It also seems to run on a Radio Shack model 3000.


             The  only  difference  between the operation  on  the  above
        systems  involves  the  timing used to fast move  the  crosshair.
        Look in the source code and set the value of a constant  MinCount
        in  procedure Crosshair.   Correctly setting it is not  mandatory
        but  it  removes the jerkyness that might otherwise exist of  the
        value is not set for your system.

             There  are several reasons why the software may not work  on
        your  system.   First,  of course,  is that you may have  a  very
        different display board than I do.  The software will try to plot
        points  using interrupt 10h.   If your graphics adapter  modifies
        this  interrupt  routine,  the  results  will  be  unpredictable.
        Secondly,  HIPLOT2  will  try  to attach a pointer to  itself  at
        interrupt  64h.   If you already have something attached to  that
        interrupt, the software will give you an error message and abort.
        Some hard disk software configurations,  for instance, may attach
        their  software to the same pointer,  so  be  careful.

             Finally,  there  have been reports of damage to monitors  if
        they are driven by the wrong sync.   Since this software does not
        address  the  hardware  directly,  there should  be  no  problem.
        HiResPlt  uses  the Turbo graphics procedures and  HIPLOT2  plots
        points  via interrupt 10H,  therefore there should be no problem.
        If you use a different display adaptor,  you should verify that a
        sync error will not occur.

          Because  of the wide variety of configurations,  the  following
        disclaimer is necessary:


        DISCLAIMER:
             This  software is provided free for public domain on an  "as

                      DESCRIPTION OF PROCEDURES IN HiResPlt

             The  plotter procedures and functions described next are all
        part of the plotter package.   The demonstration program does not
        have any procedures or functions unique to it alone.


        Hcmd(CMD,I1,I2:integer)

             This  and  Htext perform the actual interrupts  to  HIPLOT2.
        Hcmd has three arguments.   CMD is a command integer which  tells
        HIPLOT2 what you want it to do.   I1 and I2,  also integers,  are
        the parameters which may be required.  When coordinates are to be
        specified, I1 represents X and I2 represents Y.

        Command   Function
             0    Set origin (cursor) of next curve to point I1,I2
             1    Plot line from last point (origin) to I1,I2
             2    Not used from Hcmd.  See Htext
             3    Clear plotter buffer and, if selected, the CRT screen
             4    Make hardcopy on Epson MX-80 or equivalent printer
             5    Home cursor to x=0, y=0.
             6    Set mode bits to least significant byte of I1
             7    Set line pattern to pattern in I1
             8    Set pixel "color". I1=0 for white (Erase), I1=1 for
                  black (default).  Used to erase curve.
             9    Do not use
             10   Do not use
             11   Set x window to I1 and I2   (I2 > I1)  Prevents
                  plotting outside of window.
             12   Set y window to I1 and I2   (I2 > I1)  Prevents
                  plotting outside of window.
             13   Do not use



        Htext(CMD:Integer, S:String, I:Integer)-

             This  is  similar  to Hcmd except it is  intended  for  text
        command  2 where S is the string to be placed on the graph at the
        cursor location and I is the maximum length.   The string printed
        will be the lesser of the length of the string or I.


        Hdraw(IX1,IY1,IX2,IY2)-

             This draws a line from IX1,  IY1 to IX2, IY2 in the non-axis
        mode.  It is similar to Plot except it uses absolute co-ordinates
        and does not draw from the last point.


        Pattern(I:Integer)-



                                        4



             This sets the line pattern to reflect the bit pattern of the
        integer,  I.   If used,  it must be placed after Axis or SetPlot.
        Note   that   Pattern($FFFF)   will  make  a   solid   line   and
        Pattern($CCCC)  will  produce  a dotted line with  medium  length
        dots.


        ScreenOn  and ScreenOff-

             These  procedures  enable or disable plotting  to  the  CRT.
        Normally,  ScreenOn would be used unless the system does not have
        an  IBM  color  graphic adapter such as the CGA or  the  EGA,  or
        something equivalent.



        ToUpper(S:String)-   This simply converts string S to upper case.


        Beep-                This just makes a short beep near middle C.


        Alarm-               This produces a more noticeable tone



        SetOption(B:Byte)-

             HIPLOT2  has a set of 8 flags which select  options.   These
        are only useful to other procedures.  If interested, refer to the
        comments in the routine.



        Option(I:Integer, B:Boolean)-

             The  same comments as for SetOption.   This just allows  the
        individual setting of the bits.


        BW80-
             This resets the CRT back to text mode after a plot.


        Cls-
             This  clears  the screen.   It has no effect on the  plotter
        buffer.  Clearing the buffer is done with Hcmd using command 3.


        Box(IX1,IY1,IX2,IY2)-

             This will draw a box with the main diagonal from IX1, IY1 to
        IX2, IY2.




                                        5



        FindReal(IX,IY:Integer, Xval,Yval:Real)-

             This converts the integer absolute screen values to the real
        values computed by Axis.  It is not used in non-axis plotting.


        SetCross(IX,IY:Integer)-

             A utility routine for placing a crosshair on the plot.  User
        does not need to use this directly.  It is called by Crosshair.


        DaTime(I:Integer)-

             This  places  the date and the time at the  left  and  right
        sides  of the plot.   It is invoked in Axis so you do not need it
        unless you plan to use SetPlot instead.   I=0 places them at  the
        bottom, I=1 places them at the top.


        SetTypeComputer(I1,I2: Integer)-

             This  sets  the timing in the crosshair updating routine  to
        match  the type of computer used.   This routine allows low  rate
        keypresses  to  move  the  crosshair  in  small  steps  and  fast
        keypresses  to  move the crosshair in large  steps.   It  is  not
        required  to invoke this routine,  but it makes the operation  of
        the crosshair appear smoother.


        Crosshair(Ix,Iy:Integer)-

             This draws a crosshair on either an axis or a non-axis  plot
        and  allows the user to read out the values into the integers Ix,
        Iy.   In the axis mode,  Ix, Iy should be converted to real graph
        values by using FindReal.


        Hcopy(Str1,Str2:string)-

             If  Str1 is the string "PAUSE",  the routine will ask  if  a
        hardcopy  is desired.   Without it,  a hardcopy is  automatically
        made.  If Str2 is the string "EJECT", then a page will be ejected
        after plotting.

        Vcheck-

             This  is  a  function  which checks to see  if  the  HIPLOT2
        software is loaded.   If it is not,  Vcheck will be set to 0 else
        Vcheck  will be set equal the current HIPLOT2 version  number  if
        HIPLOT2 is loaded.



        FmtNum(Val:real)-


                                        6




             This is used by Axis to place a formatted number on the plot
        at the current cursor position.



        Xinit-     This is used by Axis to initialize the plotter.



        SetPlot-

             This  initializes  the plotter for subsequent  plotting  for
        cases where line drawings alone are desired (non-axis  plotting).
        The  global  scale factors are set to create a screen where  x=0,
        y=0  represents the upper left part of the screen as  in  Turbo's
        Plot.   The lower right co-ordinates are x=639, y=399.  Note that
        the  vertical  resolution is twice that of Turbo.   This  routine
        takes  the  place  of  Axis.   Either  use  SetPlot  or  Axis  to
        initialize the plotter.



        Axis(X1,X2,X3,Y1,Y2,Y3:Real)-

             This initializes the CRT and plotter buffer,  draws the axis
        and  sets the required scale factors for later plotting.   For  a
        linear X-axis,  X1 is the start value,  X2 is the stop value, and
        X3  is  the incremental value to be added at  each  tic.   For  a
        Logarithmic X-axis,  X1 is the starting decade,  x2 is the number
        of decades and x3=0.  The same is true for the Y axis.   When the
        axis is drawn, if the values to be printed require an exponential
        format,  they  are  scaled with the multiplication factor  placed
        close by in a box near the axis.   Not included in the  parameter
        list  but used as a global variable is Alpha[n],  where n  ranges
        from 1 to 9.   These are the strings to be printed.   Alpha[1] is
        the x-axis label,  Alpha[2] is the Y-axis label and the remainder
        constitute the heading.



        ReOrg-

             This  resets  the origin flag so that the next point  to  be
        plotted will become the starting point for the next curve.   This
        allows  multiple curves to be plotted.   This is used only in the
        axis plotting mode.



        Interpolate(Var I1,I2: Integer;  I3,I4: Integer)-

             When  a program asks the plotter to plot out of  the  active
        window, the plotter will stop plotting at the boundarys.  HIPLOT2
        simply   stops  placing  pixels  but  acts  as  if  the  plot  is


                                        7



        continuing.   Because only integers are passed to HIPLOT2,  it is
        possible for overflow to place the point at the other side of the
        active   window.    Interpolate   helps   calculate   the   point
        corresponding  to  the edge of the window to allow  limiting  the
        line drawn to the boundary to avoid the problem.   The routine is
        intended for internal use only.

        Hplot(X,Y:real)-

             The  values  of  X,Y are plotted after  being  scaled.   The
        scaling  is based on the values selected by the user in the  call
        to Axis.   There is no separate windowing or whatever as in  more
        sophisticated  plotter packages.   This is used only in the  axis
        mode.  For non-axis mode, use Hdraw.



        Insert(X,Y:Real, I:Integer)-

             This places the single digit integer,  I,  at a location  on
        the plot specified by X and Y.   X and Y are real quantities.   I
        ranges from 1 through 9.



        FINAL COMMENTS:

             That's  it.   The plotter package is meant to be easy to use
        at the expense of some flexibility.  This is the first version to
        be  released although I have used various versions in my own work
        for several years in Turbo-Pascal,  FORTRAN and BASIC.   I  would
        like  to  revisit this software in detail in a few months  and  I
        would  appreciate  any comments and suggested  modifications.   I
        have not released the source for HIPLOT2 yet since I plan to make
        some significant changes.  One of these may be a search algorithm
        to  place the routine at an available interrupt in case  the  one
        currently used has already been taken.   Another will be to allow
        drawing a high resolution curve on the enhanced graphics adapter.
        Please send comments and  suggestions  to  me.   Please  describe
        your  machine.    I  would  like to know if there are clones that
        have  problems  with this software.

                          A Final Note:

Cursor speed constant:

       The demonstration program was modified to allow direct
entry of MinCount99 which sets the minimum count between any two
keypresses of the same cursor control arrow.  This discriminates
between two finger taps and holding the key down.  The latter
means to move the cursor in bigger steps.  Unfortunately, this
test makes the software processor speed sensitive.

       In retrospect, I should have calculated time using the
system clock rather than relying on processor speed because of
the wide variety of machines in the world.  Alas, its too late
now.   That will be left for the next version when I add mouse
software.

       DEMOPLOT was modified at the last moment to allow you to
select the value for the speed constant.  If my suggestions do
not work best for your machine, try doubling the constant by a
factor of 2 to move the cursor quickly when the key is held down.
Reduce the constant by a factor by 2 to allow the cursor to move
in small steps on individual key presses.  You can fine tune the
value if you want.  The number is typed as a constant.



NEW HIPLOT2:
    The current HIPLOT2 version is 10-08-86 8:40PM and it replaces
    the version 2-23-86  12:08PM.  The only difference is to modify
    hardcopy routine for faster output.  It now uses INT 17h rather
    than the much slower INT 21h.


OLD WARNING MESSAGE:
    The documentation has a stiff warning to make the user pay
    attention when he first tries it on his system.  After using
    the software on a number of clones, it appears that the worst
    thing that should happen is that HIPLOT2 will not load.  It looks
    to see if the interrupt is occupied before installing itself.
    If the vector is 0000:0000 then it assumes it to be available.
    If not, it says that 64h is occupied and returns you to the
    system.   The Pascal procedures have a function Vcheck which
    looks for the 16 bit sequence A55Ah and a valid version number.
    To keep the plotting routines as fast as possible, the check is
    done only once.  If something changes the vector during a plot
    than there could be a problem.  Just make sure to include
    Vcheck in your software and avoid changing int 64h during a plot.


COMPATIBILITIES:
    I have found the software to work on:
    o IBM PC
    o IBM XT
    o IBM AT
    o PC Limited 8 Mhz AT
    o Wells American 8 Mhz
    o Wells American 10 Mhz
    o Lanier C-2400 AT
    o Radio Shack 3000

    I have not kept a list of printers that it works on but I know
    it has worked on a good number.  The only printer that did not work
    well with it was a Star Radix-15 which does not work with 123
    graphs either for the same reason.  The bit mapped graphics are
    8 pixels high and a line feed should skip 8 pixels worth.  The
    Star skips more and leaves a gap.   Just my luck that the printer
    happens to belong to my fiance'.

INCOMPATIBILITIES:
    o Some network software use the same interrupt vector and Hiplot2
    will not allow loading.  If you network, try not installing the
    network software prior to plotting to your printer.

    o As I said, the Star Radix-15 skips lines.

                   DOCUMENTATION FOR INDXCARD.BAS

                             (C) Copyright 1983 by Michael Csontos

                             INTRODUCTION

         In  spite  of  the  advantages  of computers for data bases, there are
still  uses  for the common 3" x 5" index cards. Small numbers of them are more
portable  and  accessable  than  a  computer file, and for large files (>10,000
records) the hardware is still too expensive for home use. 

         This  program  is intended to make it very easy to create and maintain
3x5  card files. By itself, it forms an electronic typewriter with full editing
facilities  for  the 3"x5" card format. It can be used with the program PC-FILE
as  a  data  entry format for small databases. PC-FILE can also be used to sort
the cards prior to printing, eliminating the tedious task of alphabetizing.

         The requirements for this program are:

                   1.) PC-DOS 1.1 with BASICA,
                   2.) two disk drives,
                   3.) 64k memory,
                   4.) Color/Graphics Adapter Card (color not used),
                   5.) Epson MX-80 (or comparable) printer.

         Optional but highly desirable items are:

                   1.)  3"  by  5"  continuous  form  index  cards, such as are
available  as  catalog  number DD8871 for $9.95/M ($8.75/M in 5M lots) (M=1000)
from:
                             Misco Inc.
                             404 Timber Lane
                             Marlboto, N. J. 07746.


                   2.)  PC-FILE,  a  database  program by Jim Button, P. O. Box
5786, Bellville WA 98006, available through many software exchanges or from:

                             Headlands Press, Inc.
                             Post Office Box 862
                             Tilburton, California 94920.

This program was tested with version 8.1 of PC-FILE.


                   3.)  A  RAM  disk  with  a printer buffer. Both INDXCARD and
PC-FILE  produce  long continuous run cycles for the disk drives. An electronic
disk drive will speed the sorting and printing operations considerably.


         There  are a number of files associated with INDXCARD. INDXCARD.BAS is
usable  by  itself  but it creates or uses the other files for some operations.
They are:

                   1.) INDXCARD.BAS - The BASIC program to create index cards,
                   2.) INDXCARD.DOC - This documentation file in ASCII form,
                   3.) INDXCARD.FRM - A card format created by INDXCARD.BAS,
                   4.) INDXCARD.KEY - Key definitions created by INDXCARD.BAS,
                   5.) INDXCARD.DTA - Card data entered through INDXCARD.BAS,
                   6.) INDXCARD.HDR - Field definitions used by PC-FILE,
                   7.) INDXCARD.RPT - Used by PC-FILE to clone sorted data,
                   8.) INDXCARD.CMP - A BASIC program to compress the data,
                   9.) INDXCARD.BAT - A DOS batch file to prepare a data disk,
                  10.) INDXCARD.INX - May be present if PC-FILE was used.



                             OPERATION

         IMPORTANT: This program creates disk records 865 bytes long. Therefore
the  BASIC  random  file  buffer  must be set to allow the reading of this size
record. Load BASICA from DOS with the command:

                   BASICA /S:1024

or load the program from DOS using the command:

                   BASICA B:INDXCARD.BAS/S:1024

or similar syntax. See page 2-4 of the IBM BASIC manual.


         INDXCARD.BAS ALONE

         If  INDXCARD.BAS  is  run  with  no other INDXCARD file on the default
drive disk, the following will occur. You will be presented with a screen image
of  an  index  card  with  eighteen lines, labeled as Field 1 to Field 18, each
having  room for 48 characters. You can use the cursor control keys to position
the  cursor  on  any line on the card and enter a short description of the data
that you will place on this line when you fill out the cards.

         You  may use the entire 48 characters for these labels. When you press
the  <Esc>  key  when filling out the cards, the entire line will be displayed,
erasing whatever was on the line on the screen. 

         The information in these labels is also used on the screen during data
entry as follows: starting at the fifth character (the default cursor position)
the next 14 characters are displayed on the left of the screen, and the next 14
characters  after that are displayed on the right. You may want to keep this in
mind in choosing field labels.

         Enter  lables  only  on the lines you want to use. If you accidentally
erase  the  field  label on a line you want to skip, press <Esc> to restore the
field number label.

         When  you  are  satisfied with the card layout, press <Alt>+<F8>. This
will  record the card layout in a file called INDXCARD.FRM on the default disk,
place  the  (possibly  truncated)  labels alongside the card form, and move the
program  to  the data entry mode. At this time the full set of function keys is
available (see FUNCTION KEYS below).

         You  may  now enter data, using the same editing keys and functions as
are  available when editing a BASIC program listing. The editing is confined to
the  boundaries  of  the  card. Editing functions behave as if only the labeled
fields  exist,  i.  e.  <enter> moves to the next field, not the next line. The
major  differences  are that the cursor does not wrap around to the next field,
and <Esc> restores the field label as well as erasing the line.

         The  initial  entry  of  any  character in a field (including <space>)
erases  the  field displayed. Pressing <Alt>+<F10> or an editing function (such
as  <Ins>)  will  prevent  this  allowing  the  displayed field to be edited or
reused.  Pressing  <enter>  will  skip  the field, but it will be erased if you
return to it and enter a character without pressing <Alt>+<F10>.

         When  the  displayed  card  looks  the way you want your index card to
look,  press <Alt>+<F8>. The card will be scanned and the data placed in a file
called  INDXCARD.DTA in the disk in the default drive. The card number and file
size  displayed below the bottom of the card will be incremented and the cursor
will  be  placed  in  column  five  on the first defined field of the card. The
contents  of the diaplayed card are not erased. If you were to press <Alt>+<F8>
twice,  a  second  identical card would be entered into the file. The next card
may  now  be  generated  by  changing  only  the  fields or characters that are
different. (Remember to press <Alt>+<F10> before entering a character change.)

         This  is the major advantage of using this program. For example if you
were  indexing  a  record  collection  and  had  a  set  of  the nine Beethoven
symphonies, you would only enter the composer, conductor, orchestra, and record
identification  information  once, then generate nine cards by editing the line
containing the name of the symphony.

         During  data entry, you may define any character key as a phrase of up
to  48  characters  to  be recalled by pressing <Alt>+<the-character-key> as in
editing a BASIC program. To do this, press <Alt>+<F4>. On line 25 of the screen
you   will   be   asked   to  identify  the  key  to  be  defined  by  pressing
<Alt>+<the-key>.  You will then be presented with a field on line 25 to fill in
with  any  phrase. After you press enter the cursor is returned to the card and
any  time thereafter the entire phrase (truncated at the edge of the card if it
is  too long) will be entered when you press <Alt>+<the-defined-key>. These key
definitions will be saved on the default disk as INDXCARD.KEY when you exit the
program.

         The  key definition feature can save considerable typing. For example,
for  a  address  card file, <Alt>+<R> could be <Rochester, New York>, <Alt>+<S>
could  be  <Scottsville, New York 14546>, etc. Thus entire lines can be entered
with  a  double keystroke. The <shift>+<F-key> and <Ctrl>+<F-key> functions may
also be defined in this way. You may also use the straight <F-key> functions by
defining  them  with the BASIC [KEY n, "ccc"] function before running INDXCARD.
This gives you a total of 68 user defined keys for this program.

         When you are finished entering data, press <Alt>+<F9>. This will place
a  end-of-file  field  in  INDXCARD.DTA  and  record INDXCARD.KEY. You may then
immediately print the cards you have just entered by setting up the printer and
pressing  any  key. If this is the first run for a print setup, it is advisable
to  press  <Alt>+<F7>  which  will  print  single  cards.  Thereafter  pressing
<Alt>+<F7> will start continuous printing. 

         To  stop  without  printing press <Esc> after pressing <Alt>+<F9>. You
may then sort the file using PC-FILE or resume data entry at a later time.

         NOTE:  It  is  important  to end the program through <Alt>+<F9>. If no
end-of-file field is present, PC-File will not be able to sort the file and the
printer will do strange things (and use up a lot of paper) when it runs off the
end of the file!



         RESUMING INDXCARD.BAS

         If  the  file  INDXCARD.DTA  is  present  on  the  default  drive when
INDXCARD.BAS  is  run,  you  will be presented with a menu giving the following
options:

                   1.) Quit and copy or rename the file,
                   2.) Print the data on index cards,
                   3.) Add new data to the file,
                   4.) Continue and erase the present file.

         Option  1  is  to  prevent  you  from  damaging data you wish to save.
Actually  no  harm  would be done by proceeding through options 2 or 3 and then
ending  the  program  in  a  normal way without changing data, however option 1
would save time. 

         Option  2  skips directly to the card printing routine. It is intended
mainly  for printing cards after they have been sorted with PC-FILE. It is also
useful if a print run has been aborted because of printer or paper problems. 

         Option  3  will  allow  you to resume entering data where you left off
from  a previous session. The end-of-file marker will be replaced with the next
card  entered  and  the  card  numbers  will continue from the last card in the
existing  file. If the data file has no end-of-file marker (because the program
was  ended  inproperly,  as  with  <Ctrl>+<Break>)  then  the new cards will be
entered directly after the last card in the file. This is a way to recover from
such  a  situation.  Simply  going  through  the data entry mode, then pressing
<Alt>+<F9> will properly terminate the file.

         Option  4  will  write  over the existing INDXCARD.DTA file. It is the
option that would normally be used, since this program in not intended to build
a  permanent  data  base, but remember that all data in the file is permanently
lost.

         In   either   option  3  or  option  4,  the  files  INDXCARD.FRM  and
INDXCARD.KEY  will  be read and the definitions in them will be used. The field
definitions  will  be  displayed and you will be given an opportunity to change
them.  This  is  an  opportunity  to  adjust  the  field names so that they are
properly  displayed  alongside  the card, or to refresh your memory of the card
layout. 

         The  file  format  used  by  this  program  allows  a  flexibility not
available  in  many data-base programes. All fields are stored on the disk even
if  they are not used. Therefore, fields may be activated and used even after a
large amount of data has been entered into the file. You may enter a label in a
blank  field  at  this  time  and enter data into that field for all subsequent
cards. You may also add that field to existing cards by using the <Ctrl>+<PgUp>
or  <Alt>+<F5> functions (see FUNCTION KEYS below). You may also delete a field
by  making  it blank at this stage. It will be skipped in subsequent data entry
and  it  will not be printed even where it exists on cards already entered. The
data  is  still  in the file, however, and may be recovered by reactivating the
field.

         The  card re-layout feature is handy if, for example, you realise that
you  need  a  company  name field in a address card file, or that you shouldn't
have  a  religion field in your employee file. The cost of this feature is that
the  files  are very large. A single-sided disk will hold only about 150 cards.
This  is  sufficient  for any single typing session, however, for data-base use
the data should be converted to another form. PC-FILE, version 8.1 provides for
cloning   files;   writing  selected  fields  to  a  new,  sortable  DTA  file.
INDXCARD.CMP  converts  the  DTA files to sequential files with blanks removed.
This  compresses the data considerably but it is left to you to write a program
to use the data.

         Once  you  have  reviewed or changed the card format, pressing any key
will  allow  you  to  proceed  to data entry. The INDXCARD.FRM and INDXCARD.KEY
files will be updated with any changes made while running the program.


         SORTING INDXCARD.DTA

         After  you have left the program by pressing <Alt>+<F9> and <Esc>, you
have  a  data  file  INDXCARD.DTA  which  is in a format that can be handled by
PC-FILE.  PC-FILE  also requires a field definition file with a .HDR extension.
INDXCARD.HDR should be provided with INDXCARD.BAS. If not, you can create it by
loading  PC-FILE  and  entering  18  field names, with each field 48 characters
long.  It might be worthwhile to make your own .HDR file this way anyway, since
the  fields  in  INDXCARD.HDR are just named FIELD 1, FIELD 2, ... etc. You can
also  copy  or  rename  your INDXCARD.DTA and INDXCARD.HDR files for protection
from  accidental erasure by option 4 of INDXCARD.BAS, however the DTA file must
be renamed INDXCARD.DTA to be printed by INBXCARD.BAS after sorting.

         See  the  documentation  provided  with  PC-FILE  for  instructions on
sorting  the  data.  In selecting the sort fields, you must identify the fields
you  have  used.  Notes made when formatting the card could be useful since you
can't  list the cards with PC-FILE until an index in created. If the first line
on the card is the one you want sorted (as it usually would be) just note which
one it is and specify it to PC-FILE.

         After  the cards are sorted, use the PC-FILE "<F6> LISt or clone" mode
to  make  a  new file from the sorted index. The format for this should also be
included  with INDXCARD.BAS as INDXCARD.RPT, but may be created with PC-FILE by
just  listing  the  18 fields in order when asked for the output format. Follow
the PC-FILE instructions for version 8.1 or later for cloning the file. The new
file  must  be  named or later renamed INDXCARD.DTA and will consist of all the
original  data  in  the  sorted order. It is not necessary to sort this file as
requested  by  PC-FILE  unless  you  are  going  to  do further work on it with
PC-FILE.


         PRINTING SORTED CARDS

         To print the file sorted by PC-FILE, load INDXCARD.BAS, place the disk
containing  the  sorted INDXCARD.DTA in the default drive, and run INDXCARD.BAS
using  option  2  above. The cards will be printed in the sorted order ready to
use or to be collated with an existing card catalog. 

         The print commands in the program are for an EPSON MX-80 printer. They
assume  six lines per inch with emphasized type. Every line is available so you
must  lay out the card to allow for top and bottom margins, i.e., the first and
last fields should not be used. The printer should be aligned so that the first
line (first field) is right at the top of the card. 

         The  cursor  is positioned at column 5 of the card form for data entry
to  allow for a left margin on the printed cards. The first five columns may be
used  on  any field by moving the cursor left before entering data, or by using
<Del>  to  remove the leading blanks from a field which has run into the end of
the line. It might be a good idea to run the program once with one or two cards
as test patterns (characters in all corners) so that you can decide on the best
positioning for your printer.

         The  printer  is  completely  reset by the program so the cards may be
aligned  by  turning  the printer off even just before printing. The printer is
left in the compressed print mode after the program ends. 

         You  may  use  the features of PC-FILE to print other types of reports
from  the  data  (after  resorting  it).  Address labels and lists may be made,
however the 48 character fields make reports difficult to print. 


         DATA COMPRESSION WITH INDXCARD.CMP

         The program INDXCARD.CMP which should be supplied with INDXCARD.BAS is
a  simple  BASIC program which reads the data in INDXCARD.DTA (preferably after
sorting)  and converts it to a sequential file. In this new file (which you are
asked  to  name)  all  leading and trailing blanks are removed from each active
field.  Blank  fields  are reduced to single <space> characters to preserve the
field  locations.  A  paragraph  symbol  (^T  or ASCII 20) followed by the card
number  (the record number from the sorted file) is inserted between each card.
This  information  should  be sufficient to reconstruct the data except for any
indentations (tabs). 

         INDXCARD.CMP  is  not  intended to be particulatly user-friendly since
you  need  to  know  how to write a BASIC file handling program to use the data
after  it is compressed. If you understand the commands necessary, it should be
easy  to convert the data in these files for use by other databases, to combine
or collate files, and to print specialized reports. At least these files can be
edited and searched by EDLIN from PC-DOS.

         An  attempt  was  made  to  write  a  program  that  would  remove the
end-of-file marker from DTA files to allow them to be combined using the PC-DOS
1.1  [COPY]  concatenation  feature.  The  attempt  was unsuccessful, however a
custom  BASIC  program that combines and colates DTA files using selected parts
of  selected  fields  could  be  easily written to compress any particular card
layout.


         FUNCTION KEYS

         Extensive  use  is  made of the function keys by this program. The key
combinations  <Alt>+<F1>  through  <Alt>+<F10> are used to control the program.
The  rest  of  the  keys  that  can  be  used  with  <Alt>,  <shift>, or <Ctrl>
combinations  may  be  programed  with  character  strings  by  the  user. This
considerably reduces the number of keystrokes needed to enter data.

         <Alt>+<F1> - QUIT

         This key combination is recognised during most parts of the program to
allow  you  to  return  directly  to  BASIC  without  going through the printer
instruction screen display. If you are in the data entry mode it will NOT place
the end-of-field marker on the file. You can continue data entry where you left
off  by  rerunning  the program, but you cannot use PC-FILE on the data and you
should not try to print cards from the file. 

         <Alt>+<F2> - LIST FUNCTION KEYS

         This  will  cause  the printer to print a short list of the <Alt>+<Fn>
key assignments to be placed next to the keyboard for reference while using the
program.

         <Alt>+<F3> - LIST <Alt>+<character> KEY ASSIGNMENTS

         This  will  produce  on  the printer a full page listing of all of the
user  and programed key assignments. All of the character keys (A-Z, 1-0, - and
=)  may  be  assigned  using  <Alt>+<F4>.  If  assignments have been made or if
assignments  were  read  from  the  disk  file  INDXCARD.KEY, then they will be
listed,  along with any <shift>+<Fn> and <Ctrl>+<Fn> assignments. The programed
<Alt>+<Fn>  key  assignments  will  be listed on the bottom of the page as with
<Alt>+<F2> above.

         <Alt>+<F4> - PROGRAM A USER KEY ASSIGNMENT

         When this key combination is pressed during data entry, line 25 of the
screen  is  used  first to identify the key combination to be assigned, then to
enter the string to be assigned to that key combination. 

         When  asked  to  enter  <Alt>+<the-key-you-want-to-use>  press the key
combination that you want to program. In spite of the instruction, you may also
press   <Ctrl>+<Fn>   and   <shift>+<Fn>   to   program   them  the  same  way.
<Ctrl>+<character> and obviously <shift>+<character> don't work.

         A  48  character  string may be entered, only backspace may be used or
editing.  When the string is entered press <enter>. You will be returned to the
previous  cursor position and may immediately use the character string you have
just entered by pressing the key combination.

         Character   strings   entered   in  card  lines  behave  just  as  the
<Alt>+<character>  keys  do  in  BASIC,  where  <Alt>+<P> produces PRINT on the
screen.  Strings  may  be  inserted with the <Ins> key. The major difference is
that  the end of the line will always be the edge of the card. There is no line
wrap  since  for  this  application  it  would  usually  go into a field with a
different data definition.

         You  lose  a  previous  key  definition  as  soon as you enter the key
definition  mode. If you press <Alt>+<F4> by mistake, just reenter the shortest
key definition (or an undefined key) on your list. 

         All  current key definitions are automatically saved when you exit the
program  through  <Alt>+<F9>.  They will be lost (and any previous INDXCARD.KEY
file  preserved) if you exit through <Alt>+<F1> or other means. Key definitions
are  automatically restored when you run the program if INDXCARD.KEY is present
on the default drive.

         <Alt>+<F5> and <Alt>+<F6> PAGE THROUGH CARDS

         During  data entry you may move backward and foreward through the card
file  with these keys. <Alt>+<F5> moves toward lower numbered cards; <Alt>+<F6>
moves  toward  the  end  of  the  file.  Similar  functins are also provided by
<Ctrl>+<PgUp>  (toward  the  beginning  of  the file) and <Ctrl>+<PgDn> (toward
higher card numbers).

         Each  keystroke  moves  one  card number in the appropriate direction.
Since  during  normal data entry, the next card's display contains the previous
card's  contents  on the screen until changed, the first press of <Alt>+<F5> or
<Ctrl>+<PgUp>  will  appear  to  change  only  the card number. However if this
action is followed by <Alt>+<F6> or <Ctrl>+<PgDn>, you will be presented with a
blank  card, which is the actual content of the last card in the file before an
entry is made. 

         You  may  edit  any  card  displayed after a paging operation and then
enter  the changes in that card by pressing <Alt>+<F8>. That card will now have
the  updated  information and you will be returned to the last (unentered) card
in the file with the screen showing the content of the changed card. 

         If  you just press <Alt>+<F8> at a card reached by paging, the data on
that  card  will be reentered unchanged and you will also transfer that data to
the  last  card position. This can be useful if, for example, you remember that
five cards back you entered an almost identical address to the one you must now
enter.  Simply  press <Alt>+<F5> five times, check to see that you have reached
the  right  card,  then  press <Alt>+<F8>. You need now make only the necessary
changes and enter the new card. 

         The IBM keyboard's typamatic feature works for the function keys. With
<Alt>+<F5>  and  <Alt>+<F6> the program will skip rapidly through the number of
pages held in the keyboard buffer. This does not work for the <Ctrl>+<PgUp> and
<Ctrl>+<PgDn>  keys. Thus you can skip through the file by rapidly pressing the
<Alt>+<F5>  or  <Alt>+<F6> combinations or display it page by page using the Pg
keys.  No  not  hold  down  the  keys when you hear the buffer-full alarm tone.
Somewhere  (DOS,  BASIC,  or  INDXCARD) there is something that doesn't like to
process an [INKEY$] command while scanning the screen memory while sounding the
buffer alarm! 

         <Alt>+<F7> - UNASSIGNED

         This  key  is used to provide alternate continuation modes for several
parts of the program but to avoid confusion is unassigned during data entry.

         <Alt>+<F8> - RECORD DATA; FINISHED WITH CARD

         The  card  is  scanned  and the data is recorded in the disk file. All
fields  that  are defined in the card format set-up at the start of the program
are  scanned, other fields are skipped. If you have changed the card format and
paged  back  to  a card entered before the change, some lines on the screen may
not  be  scanned and the data will be erased from the disk file. This is useful
to clear old data, or a problem if you wish to preserve it. This program is not
meant to be a data base.

         Data  on  the  screen  will not be saved unless <Alt>+<F8> is pressed.
Therefore  be  sure  to  use  it  before  ending the program with <Alt>+<F1> or
<Alt>+<F9>. 

         The  scanning process is somewhat slow, however the keyboard buffer is
not  cleared  so  in  continuous data entry you can enter the first line of the
next  card  while  the  last card is being scanned. Since the user-defined keys
count  as single keys in the buffer, you can enter a considerable amount during
the scan.

         <Alt>+<F9> - END DATA ENTRY; FINISHED WITH CARDS

         The  end of file record for PC-FILE and printing is placed on the disk
and  the program is made ready to end or print cards. The end of file record is
just  the  last entered card data with backslashes (\) at the beginning and end
of the record. 

         After  pressing  <Alt>+<F9>  you  are  given  the choice of ending the
progrqm  with  <Esc>, printing the first card with <Alt>+<F7> or printing cards
continuously  after pressing any key. This selection was based on making it the
easiest to use the program as an electronic typewriter for printing a few cards
at time. 

         <Alt>+<F10> - USE CURRENT LINE AS DISPLAYED

         For  rapid  continuous  entry  of new data, the line from the previous
card  is erased as soon as new data is started. If you use a key such as <Ins>,
<Del>  or  <End> the program assumes that you want to edit the line and doesn't
erase it. However to distinguish between new data and a change when a character
is the first entry on a line, you must press <Alt>+<F10> first.



         OPERATING PROCEDURES

         INDXCARD.BAS  is  simple enough to operate if all you want to do is to
print  a few index cards at a time without sorting. However doing large batches
with  single  sided  disks is more complicated because of the large size of the
files.  If  all  of  the PC-FILE and INDXCARD files are on one disk there is no
room  for  data. Therefore two procedures are provided; one for two disk drives
and  another  for two drives plus a RAM drive electronic disk. Both assume that
all  of  the  required  program files are on one operating disk (called Program
Disk).  The Program disk contains all of the files associated with INDXCARD.BAS
and all of the files associated with PC-FILE.


         PROCEDURE WITH TWO DRIVES

         1.) Start the PC in DOS with default drive A:.
         2.) Place the Program Disk in drive A: and a formatted but blank data
                   disk in drive B:
         3.) Type INDXCARD <enter>. This will run the file INDXCARD.BAT which
                   copies the files INDXCARD.FRM, .KEY, .HDR AND .RPT to the
                   data disk. 
         4.) Place your DOS disk in drive A, make drive B: the default drive
                   (type B:<enter>) and load BASICA with the /S:1024 option
                   (type A:BASICA/S:1024).
         5.) Place the Program Disk in drive A: and run INDXCARD.BAS (type
                   LOAD"A:INDXCARD",R<enter>).
         6.) Run through the program. entering data and ending with <Alt>+<F9>
                   then <Esc>.
         7.) Place your DOS disk in drive A: and type SYSTEM<enter> to return
                   to DOS. Type A:<enter> to make drive A: the default drive.
         8.) Place the Program Disk in drive A: and type PC-FILE<enter>. This
                   will load PC-FILE.  FolIow PC-FILE instructions to tell it
                   that the data is in drive B: and to sort the data. 
         9.) Place another formatted data disk in drive A:. Tell PC-FILE to
                   clone the data to A:INDXCARD.DTA and run the list routine.
        10.) Place your DOS disk in drive A: and exit PC-FILE
        11.) Replace the second data disk into drive a: and type COPY B:*.FRM
                   A:<ENTER>.  You now have a sorted data file and its format
                   on the second data disk in drive A: and your intact
                   original data and its PC-FILE index on the first data disk
                   in drive B:.
        12.) Place the second data disk in drive B:, and your DOS disk in
                   drive A:. Make drive B: the default drive (type B:<enter>)
                   and load BASICA (type A:BASICA /S:1048<enter>).
        13.) Place the Program Disk in drive a and type RUN"A:INDXCARD".
                   Select option 2 on the menu and follow the instructions to
                   print the sorted cards.

         The  above  procedure is quite formidable. It is actually a worst-case
procedure.  For  someone used to working with disk files most of the steps come
automatically.  Considerable  disk switching can be saved by making the Program
Disk  into a DOS disk. However it also illustrates that two single-sided drives
are barely adaquate for serious data-base work.


         PROCEDURE FOR TWO DRIVES PLUS AN ELECTRONIC (RAM) DRIVE

         This  assumes  that  the  RAM drive is set up to be the same size as a
disk  drive  and  the  Program  Disk  is also a DOS disk (is a system disk with
BASICA on it as well as all PC-FILE and INDXCARD files.

         1.) Start the PC with the Program Disk in drive A: and make B: the
                   default drive (type B:<enter>).
         2.)  Place a formatted data disk in drive B: and type A: INDXCARD to
                   transfer the control files. 
         3.) Run INDXCARD by typing A:BASICA A:INDXCARD/S:1024<ENTER>, then
                   RUN<enter>.
         4.) Enter data and end the program with <Alt>+<F9> then <Esc>. Type
                   SYSTEM to return to DOS.
         5.) Type A:PC-FILE<enter> and sort the file in drive B:.
         6.) Use the list option of PC-FILE to clone the sorted data to the
                   RAM drive. Exit PC-FILE.
         7:) Copy INDXCARD.FRM to the RAM drive. Make the RAM drive the
                   default drive.
         8:) Reload BASICA and INDXCARD as before and run option 2 to print
                   the cards. 


         If  you  want  to  process the sorted data further it can be copied to
another  data  disk  or  copied  over the original data file. Most of the above
steps  could  be  placed into an AUTOEXEC.BAT file for futher automation of the
process.


         MISCELLANEOUS OBSERVATIONS

         The <Ins> mode in data entry allows any character code above 031 to be
inserted.  If  your  printer  will  print foreign characters or you want to use
printer  graphics  on your cards, press <Ins> then hold down <Alt> while keying
in  the  ASCII  code  on the numeric keypad. The character will appear when you
release  <Alt>.  These codes can be found in Appendix G of the IBM Basic manual
(for  the screen and IBM printers) or Appendix F of the EPSON manual (for EPSON
printers). 

         A  single-sided  double-density  8-segment format disk will hold about
160  cards  plus the required control files transfered by INDXCARD.BAT. and the
PC-FILE  generated .INX file. If you fail to watch the card numbers shown under
the  card  form on the screen and run out of disk space, you may not be able to
recover  even by erasing all but the .DTA and .HDR files. Therefore it might be
useful  to include a dummy file of about 7K bytes on the data disk which can be
erased  to  make  room for the .INX file if necessary. Alternativly, if you are
using a RAM disk, you can define it to be 10k bytes larger than your mechanical
drives and use it to sort the file. 

         In  no  event  will  the  author  be  liable  to  you for any damages,
including  any  lost profits, lost savings or other incidental or consequential
damages  arising out of the use or of the inability to use these programs, even
if  the  author has been advised of the possibility of such damages, or for any
claim by any other party.

     MAILING LIST PROGRAM  v1.0  by Joe Long

     This is a straightforward mailing list program written as an exercise.
It is fairly powerful, allowing sorting by four fields and keying printing of
labels by any field.  It will print one across or two across labels.  It was
repeatedly modified and expanded in scope as it grew, so it is not as elegantly
structured as it should be.  It has had little testing, so probably has bugs --
please report any bugs to me at the address listed in the program heading.

     The program has five files open at once, and uses the function keys,  so
BASICA must be called with five file buffers specified.  Call as
"BASICA/F:5/S:512".

     The program is nearly self-explanatory.  Use the "tab" key or cursor
control keys to move about the form.  "Tab" only moves forward.  "Esc" deletes
the current record from the file.  You are always given a chance to change your
ind before the disc is modified, except when inputting a new record.

     Sorting is done by maintaining a separate index file for the four sort
fields.  Only these files are sorted, the main file is never shuffled.
Searches are done by a binary search, so the index files must be sorted before
a search if even one record has been changed.  An insertion sort is used, which
is fast when the list is almost in order (as will be the case when only a few
records have been changed since the last sort).  If you enter a large number of
new records, the sort can get very slow.  I have a compiled version available,
which I have not uploaded because of its large size (42K).  You can get it by
sending me a blank, formatted disc in a self-addressed return mailer WITH
POSTAGE.

     The program does a LOT of disc I/O.  It will run much faster if you have a
"ramdisc" (a virtual disc drive in high RAM).  Just change the drive
specification on lines 160, 180, 200, 220, and 240 to the ramdrive.

     Feel free to modify or expand this program as you wish.  It is fairly
well self-documented, so modification should not be difficult.

     If you have a color monitor, change the values of FG, BG, BD, and HI to
whatever colors suit you.  They are now set for B/W monitors.

     My only reason for the 1,000 record limit is the feeling that by that time
the program will have gotten intolerably slow anyway, at least until the
compiled version is done.  If you have the disc space, and a compiler, you may
wnat to increase this.  Notice that I maintain dynamic file allocation;
eleted records are re-used to keep the file from growing unnecessarily.  Up to
50 deleted record numbers are saved at one time.

     If you have any questions, write me or leave a message on the Capitol BBS.
eted record numbers are saved at on

            This  package  of programs contain  a  demonstration  program
        written  in  Turbo  Pascal  along with a set  of  procedures  for
        plotting  high resolution (640x400 pixel)  graphs.   The  plotter
        routines are intended for engineering and scientific applications
        where  X-Y  coordinate line plots are needed and  where  standard
        color graphic adaptor screen dumps are inadequate.   The routines
        are  simple  to use and provide a high resolution hard copy  from
        printers compatible with the Epson MX-80/FX-80 dot graphics.   It
        has  been tested on IBM PCs and ATs and a Radio Shack model 3000.
        I  have  not  tried it on any other  systems.   The  software  is
        composed of three files:

             o DEMOPLOT.PAS - A  pascal demonstration program which  uses
             the Pascal graphics procedures contained in HiResPlt.pas.

             o HiResPlt.PAS - A   file  of  Pascal  routines  which   are
             necessary to draw axis and perform plotting.  The procedures
             work in conjunction with another program,  HIPLOT2,  written
             in  assembly  code  which actually  performs  the  plotting.
             HiResPlt.pas  is used as an "include" file in programs  like
             DEMOPLOT which require graphics.

             o HIPLOT2.EXE - This  assembly code plotter attaches  itself
             to   the   system  as  a   run-and-remain-resident   program
             accessible via a single interrupt.  Access through interrupt
             was   chosen  to  simplify  interfacing  to   higher   level
             languages.  As a result, only the interface routines need to
             be customized to a particular compiler.

             o PLOTTER.DOC - This description of the plotter software.

        BACKGROUND:

             HIPLOT2   was  originally  written  to  provide   a   higher
        resolution  curve  than  was  available with  the  640x200  pixel
        resolution  of  an IBM Color  Graphics  Adapter  (CGA).   HIPLOT2
        "draws"  the plot into a large buffer to a resolution of  640x400
        pixels.   At  the  same  time,  it can optionally  draw  a  lower
        resolution  curve of 640x200 pixels on the CGA.   When a hardcopy
        is requested, the higher resolution curve is sent from the buffer
        to the printer in the Epson bit graphics format.   This is to  be
        contrasted  with a screen dump which has the same  resolution  as
        the display.

             Because   the  printed  resolution  is  different  from  the
        displayed  resolution,  the characters stored in the  buffer  and
        printed  on the hardcopy are selected from a different  character
        matrix  made  compatible with the higher  resolution.   The  CGA,
        however,  receives  the  lower resolution IBM ROM character  set.
        HIPLOT2 maps the character matrix to the CGA differently than  is
        done in other graphics packages like BASICA.   Mapping is done on


                                        1



        a  pixel boundary where the characters can be placed anywhere  on
        the CGA display.   In BASICA,  placement is restricted to column-
        row  boundarys.   Bit mapping provides flexibility when  labeling
        axis tics.

             Future  plans  include modifying HIPLOT2 to use  the  higher
        resolution  of  the IBM Enhanced Graphics Adapter (EGA) if  used,
        however  until  then,  the software uses the  highest  resolution
        available  on  the CGA.   It will work on the EGA  but  only  the
        reduced 640x200 resolution compatible with the CGA.  You may need
        to type "mode co80" before running the graphics software.  If you
        notice  loss  of  sync  when using a card other  than  the  color
        graphics  card,  you may need to reboot to avoid damage  to  your
        monitor.



             DEMOPLOT.PAS  is  a small demonstration program.   The  user
        should  try the demonstration program first to see how it  works.
        This  is done by first running HIPLOT2 to load the  machine  code
        plotter   into  memory  and  then  running  Turbo   Pascal   with
        DEMOPLOT.PAS as the work file.   Again, you may need to run "mode
        co80" before running Turbo if you use an EGA.

             The  demonstration  program first asks if a  color  graphics
        card is available.   If a no is given,  plotting to the screen is
        suppressed.   The  program then draws a diagonal line and a  box.
        It  then allows the user to position a crosshair using the cursor
        keys.   Absolute  coordinates  are displayed at the  top  of  the
        screen.  When the user presses <enter>, the program will ask if a
        hard  copy is desired.   A "y" followed by an <enter> will  cause
        the  program  to attempt to send the plot to  the  printer.   Any
        other character or simply an <enter> will cause the program to go
        to the next demonstration.

             The  next  demonstration  is a more realistic  plot  of  the
        absolute  value of a sine wave followed by a simple dotted  line.
        Again,  the  user  is  given  the opportunity  to  read  out  the
        coordinates of the curve with a crosshair and then to get a  hard
        copy of the curve.   To simply view the operation of the plotter,
        simply  keep hitting <enter> and the demonstration will  progress
        from beginning to end.

             If you have the same hardware configuration as I, you should
        have no problem running the program.  I do not have the resources
        to  try  the software on any more than a few systems so I  cannot
        say  what will or will not work.   The two systems which  I  have
        been able to use the software on are:

        Configuration:      1                        2
        Type:               IBM PC, 256k main board  IBM AT
        Graphics board:     IBM CGA                  IBM EGA
        Disc Drives:        2ea. Teac DSDD Floppies  20 Mbyte hard disc
        Total RAM:          640k                     512k
        IBM DOS version:    2.0                      3.10

             It also seems to run on a Radio Shack model 3000.


             The  only  difference  between the operation  on  the  above
        systems  involves  the  timing used to fast move  the  crosshair.
        Look in the source code and set the value of a constant  MinCount
        in  procedure Crosshair.   Correctly setting it is not  mandatory
        but  it  removes the jerkyness that might otherwise exist of  the
        value is not set for your system.

             There  are several reasons why the software may not work  on
        your  system.   First,  of course,  is that you may have  a  very
        different display board than I do.  The software will try to plot
        points  using interrupt 10h.   If your graphics adapter  modifies
        this  interrupt  routine,  the  results  will  be  unpredictable.
        Secondly,  HIPLOT2  will  try  to attach a pointer to  itself  at
        interrupt  64h.   If you already have something attached to  that
        interrupt, the software will give you an error message and abort.
        Some hard disk software configurations,  for instance, may attach
        their  software to the same pointer,  so  be  careful.

             Finally,  there  have been reports of damage to monitors  if
        they are driven by the wrong sync.   Since this software does not
        address  the  hardware  directly,  there should  be  no  problem.
        HiResPlt  uses  the Turbo graphics procedures and  HIPLOT2  plots
        points  via interrupt 10H,  therefore there should be no problem.
        If you use a different display adaptor,  you should verify that a
        sync error will not occur.

          Because  of the wide variety of configurations,  the  following
        disclaimer is necessary:

                      DESCRIPTION OF PROCEDURES IN HiResPlt

             The  plotter procedures and functions described next are all
        part of the plotter package.   The demonstration program does not
        have any procedures or functions unique to it alone.


        Hcmd(CMD,I1,I2:integer)

             This  and  Htext perform the actual interrupts  to  HIPLOT2.
        Hcmd has three arguments.   CMD is a command integer which  tells
        HIPLOT2 what you want it to do.   I1 and I2,  also integers,  are
        the parameters which may be required.  When coordinates are to be
        specified, I1 represents X and I2 represents Y.

        Command   Function
             0    Set origin (cursor) of next curve to point I1,I2
             1    Plot line from last point (origin) to I1,I2
             2    Not used from Hcmd.  See Htext
             3    Clear plotter buffer and, if selected, the CRT screen
             4    Make hardcopy on Epson MX-80 or equivalent printer
             5    Home cursor to x=0, y=0.
             6    Set mode bits to least significant byte of I1
             7    Set line pattern to pattern in I1
             8    Set pixel "color". I1=0 for white (Erase), I1=1 for
                  black (default).  Used to erase curve.
             9    Do not use
             10   Do not use
             11   Set x window to I1 and I2   (I2 > I1)  Prevents
                  plotting outside of window.
             12   Set y window to I1 and I2   (I2 > I1)  Prevents
                  plotting outside of window.
             13   Do not use



        Htext(CMD:Integer, S:String, I:Integer)-

             This  is  similar  to Hcmd except it is  intended  for  text
        command  2 where S is the string to be placed on the graph at the
        cursor location and I is the maximum length.   The string printed
        will be the lesser of the length of the string or I.


        Hdraw(IX1,IY1,IX2,IY2)-

             This draws a line from IX1,  IY1 to IX2, IY2 in the non-axis
        mode.  It is similar to Plot except it uses absolute co-ordinates
        and does not draw from the last point.


        Pattern(I:Integer)-



                                        4



             This sets the line pattern to reflect the bit pattern of the
        integer,  I.   If used,  it must be placed after Axis or SetPlot.
        Note   that   Pattern($FFFF)   will  make  a   solid   line   and
        Pattern($CCCC)  will  produce  a dotted line with  medium  length
        dots.


        ScreenOn  and ScreenOff-

             These  procedures  enable or disable plotting  to  the  CRT.
        Normally,  ScreenOn would be used unless the system does not have
        an  IBM  color  graphic adapter such as the CGA or  the  EGA,  or
        something equivalent.



        ToUpper(S:String)-   This simply converts string S to upper case.


        Beep-                This just makes a short beep near middle C.


        Alarm-               This produces a more noticeable tone



        SetOption(B:Byte)-

             HIPLOT2  has a set of 8 flags which select  options.   These
        are only useful to other procedures.  If interested, refer to the
        comments in the routine.



        Option(I:Integer, B:Boolean)-

             The  same comments as for SetOption.   This just allows  the
        individual setting of the bits.


        BW80-
             This resets the CRT back to text mode after a plot.


        Cls-
             This  clears  the screen.   It has no effect on the  plotter
        buffer.  Clearing the buffer is done with Hcmd using command 3.


        Box(IX1,IY1,IX2,IY2)-

             This will draw a box with the main diagonal from IX1, IY1 to
        IX2, IY2.




                                        5



        FindReal(IX,IY:Integer, Xval,Yval:Real)-

             This converts the integer absolute screen values to the real
        values computed by Axis.  It is not used in non-axis plotting.


        SetCross(IX,IY:Integer)-

             A utility routine for placing a crosshair on the plot.  User
        does not need to use this directly.  It is called by Crosshair.


        DaTime(I:Integer)-

             This  places  the date and the time at the  left  and  right
        sides  of the plot.   It is invoked in Axis so you do not need it
        unless you plan to use SetPlot instead.   I=0 places them at  the
        bottom, I=1 places them at the top.


        SetTypeComputer(I1,I2: Integer)-

             This  sets  the timing in the crosshair updating routine  to
        match  the type of computer used.   This routine allows low  rate
        keypresses  to  move  the  crosshair  in  small  steps  and  fast
        keypresses  to  move the crosshair in large  steps.   It  is  not
        required  to invoke this routine,  but it makes the operation  of
        the crosshair appear smoother.


        Crosshair(Ix,Iy:Integer)-

             This draws a crosshair on either an axis or a non-axis  plot
        and  allows the user to read out the values into the integers Ix,
        Iy.   In the axis mode,  Ix, Iy should be converted to real graph
        values by using FindReal.


        Hcopy(Str1,Str2:string)-

             If  Str1 is the string "PAUSE",  the routine will ask  if  a
        hardcopy  is desired.   Without it,  a hardcopy is  automatically
        made.  If Str2 is the string "EJECT", then a page will be ejected
        after plotting.

        Vcheck-

             This  is  a  function  which checks to see  if  the  HIPLOT2
        software is loaded.   If it is not,  Vcheck will be set to 0 else
        Vcheck  will be set equal the current HIPLOT2 version  number  if
        HIPLOT2 is loaded.



        FmtNum(Val:real)-


                                        6




             This is used by Axis to place a formatted number on the plot
        at the current cursor position.



        Xinit-     This is used by Axis to initialize the plotter.



        SetPlot-

             This  initializes  the plotter for subsequent  plotting  for
        cases where line drawings alone are desired (non-axis  plotting).
        The  global  scale factors are set to create a screen where  x=0,
        y=0  represents the upper left part of the screen as  in  Turbo's
        Plot.   The lower right co-ordinates are x=639, y=399.  Note that
        the  vertical  resolution is twice that of Turbo.   This  routine
        takes  the  place  of  Axis.   Either  use  SetPlot  or  Axis  to
        initialize the plotter.



        Axis(X1,X2,X3,Y1,Y2,Y3:Real)-

             This initializes the CRT and plotter buffer,  draws the axis
        and  sets the required scale factors for later plotting.   For  a
        linear X-axis,  X1 is the start value,  X2 is the stop value, and
        X3  is  the incremental value to be added at  each  tic.   For  a
        Logarithmic X-axis,  X1 is the starting decade,  x2 is the number
        of decades and x3=0.  The same is true for the Y axis.   When the
        axis is drawn, if the values to be printed require an exponential
        format,  they  are  scaled with the multiplication factor  placed
        close by in a box near the axis.   Not included in the  parameter
        list  but used as a global variable is Alpha[n],  where n  ranges
        from 1 to 9.   These are the strings to be printed.   Alpha[1] is
        the x-axis label,  Alpha[2] is the Y-axis label and the remainder
        constitute the heading.



        ReOrg-

             This  resets  the origin flag so that the next point  to  be
        plotted will become the starting point for the next curve.   This
        allows  multiple curves to be plotted.   This is used only in the
        axis plotting mode.



        Interpolate(Var I1,I2: Integer;  I3,I4: Integer)-

             When  a program asks the plotter to plot out of  the  active
        window, the plotter will stop plotting at the boundarys.  HIPLOT2
        simply   stops  placing  pixels  but  acts  as  if  the  plot  is


                                        7



        continuing.   Because only integers are passed to HIPLOT2,  it is
        possible for overflow to place the point at the other side of the
        active   window.    Interpolate   helps   calculate   the   point
        corresponding  to  the edge of the window to allow  limiting  the
        line drawn to the boundary to avoid the problem.   The routine is
        intended for internal use only.

        Hplot(X,Y:real)-

             The  values  of  X,Y are plotted after  being  scaled.   The
        scaling  is based on the values selected by the user in the  call
        to Axis.   There is no separate windowing or whatever as in  more
        sophisticated  plotter packages.   This is used only in the  axis
        mode.  For non-axis mode, use Hdraw.



        Insert(X,Y:Real, I:Integer)-

             This places the single digit integer,  I,  at a location  on
        the plot specified by X and Y.   X and Y are real quantities.   I
        ranges from 1 through 9.



        FINAL COMMENTS:

             That's  it.   The plotter package is meant to be easy to use
        at the expense of some flexibility.  This is the first version to
        be  released although I have used various versions in my own work
        for several years in Turbo-Pascal,  FORTRAN and BASIC.   I  would
        like  to  revisit this software in detail in a few months  and  I
        would  appreciate  any comments and suggested  modifications.   I
        have not released the source for HIPLOT2 yet since I plan to make
        some significant changes.  One of these may be a search algorithm
        to  place the routine at an available interrupt in case  the  one
        currently used has already been taken.   Another will be to allow
        drawing a high resolution curve on the enhanced graphics adapter.
        Please send comments and  suggestions  to  me.   Please  describe
        your  machine.    I  would  like to know if there are clones that
        have  problems  with this software.

     PMB - Preventive Maintanence, Bill, and Message Program
     -------------------------------------------------------


     This program provides a way of keeping track of events which
occur  periodically such as bills,  preventive maintanence items,
dentist  appointments,	yearly vet checks for the family  animal,
and  once-only	items such as important meetings planned  far  in
advance.  The program is designed to be operated weekly and, when
requested,  will  print  out the items due in the  following  two
weeks.	 To operate,  you must create two files with an editor or
with  BASICA.	The  file structure is ASCII in  a  format  which
almosts resembles a program to BASICA.	This format lets you edit
the  file,  should you ever need to,  using BASICA rather than an
editor.   Therefore, the disk containing your files need not have
both an editor and BASICA.

     First, enter BASICA and type the following:

1 '
2 ,"CARNAME1","CARNAME2","CARNAME3","CARNAME4",NCAR


     The  first line is a comment line and will be filled by  PMB
each time you save an updated file.

     The  second  line contains a set of 1-4 string names of  the
vehicles  that you want to place on a  mileage-based  maintanence
schedule.   NCAR  is  a  single  digit number of  the  number  of
significant  names desired (1,2,3 or 4).   Use two double  qoutes
for empty entries.

     Then type SAVE "ITEMDATA.DAT",A  to save the file.  REMEMBER
TO  APPEND THE 'A' OPTION TO SAVE AN ASCII FILE.   Also create  a
backup file:  SAVE "ITEMDATA.BAK",A

     For example, use:

1 '
2 ,"FORD","CHEVY","HONDA","",3

SAVE "ITEMDATA.DAT",A
SAVE "ITEMDATA.BAK",A
LOAD "PMB
RUN

     At  this  point,	you  can  run  the  program.   It  should
automatically load the data file and list the commands available.

     Test the program by inserting, with the I command, the items
below:
Enter Command: ? I


     The program then prints out the instructions for the command
and:

Enter type: ? 1

Enter message: v...........................................v
	       Time for income tax

Enter Month: ? 2
Enter Day: ? 1
Enter last two digits of year: ? 87

     The program should then print:

Num Type TrigNo Para-1	.........Comment........
=== ==== ====== ======	========================
  1    1   1492      0	2/1/84	 = Time for income tax


     Then save the file with the "S" command.   When you load and
run the program,  it should only display the once-only message if
the date is within one week of the date given, or later.  It will
then  continue	to  display the message each  time  you  run  the
program until you kill (K) the message.

     When  you	save the datafile,  (S),  the program will add	a
comment  line in line 1 with the creation date and the items  you
have inserted,	(I).  If you then exit, (E) and load itemdata.dat
and list it, you should get:


1 'ITEMDATA.DAT - Data file for PMB as of <what ever the date is>
2 ,"FORD","CHEVY","HONDA","",3
3 , 1 , 1492 ,"2/1/84   = Time for income tax", 0 , 0 , 0

     The line number is to allow you to use the BASICA editor  if
you want to modify the file.   In line 3,  the next number is the
item type, 1 means one-shot message, no renewal.  The 1492 is the
number	of days after 1 Jan 1980 (Its NOT Julian,  but	then,  so
what?)	The last 3 numbers are parameters, only one is used.  The
remainder are there for growth.

     You can try some other examples and change the date with the
D command to test the results.

                          A Final Note:

Cursor speed constant:

       The demonstration program was modified to allow direct
entry of MinCount99 which sets the minimum count between any two
keypresses of the same cursor control arrow.  This discriminates
between two finger taps and holding the key down.  The latter
means to move the cursor in bigger steps.  Unfortunately, this
test makes the software processor speed sensitive.

       In retrospect, I should have calculated time using the
system clock rather than relying on processor speed because of
the wide variety of machines in the world.  Alas, its too late
now.   That will be left for the next version when I add mouse
software.

       DEMOPLOT was modified at the last moment to allow you to
select the value for the speed constant.  If my suggestions do
not work best for your machine, try doubling the constant by a
factor of 2 to move the cursor quickly when the key is held down.
Reduce the constant by a factor by 2 to allow the cursor to move
in small steps on individual key presses.  You can fine tune the
value if you want.  The number is typed as a constant.



NEW HIPLOT2:
    The current HIPLOT2 version is 10-08-86 8:40PM and it replaces
    the version 2-23-86  12:08PM.  The only difference is to modify
    hardcopy routine for faster output.  It now uses INT 17h rather
    than the much slower INT 21h.


OLD WARNING MESSAGE:
    The documentation has a stiff warning to make the user pay
    attention when he first tries it on his system.  After using
    the software on a number of clones, it appears that the worst
    thing that should happen is that HIPLOT2 will not load.  It looks
    to see if the interrupt is occupied before installing itself.
    If the vector is 0000:0000 then it assumes it to be available.
    If not, it says that 64h is occupied and returns you to the
    system.   The Pascal procedures have a function Vcheck which
    looks for the 16 bit sequence A55Ah and a valid version number.
    To keep the plotting routines as fast as possible, the check is
    done only once.  If something changes the vector during a plot
    than there could be a problem.  Just make sure to include
    Vcheck in your software and avoid changing int 64h during a plot.


COMPATIBILITIES:
    I have found the software to work on:
    o IBM PC
    o IBM XT
    o IBM AT
    o PC Limited 8 Mhz AT
    o Wells American 8 Mhz
    o Wells American 10 Mhz
    o Lanier C-2400 AT
    o Radio Shack 3000

    I have not kept a list of printers that it works on but I know
    it has worked on a good number.  The only printer that did not work
    well with it was a Star Radix-15 which does not work with 123
    graphs either for the same reason.  The bit mapped graphics are
    8 pixels high and a line feed should skip 8 pixels worth.  The
    Star skips more and leaves a gap.   Just my luck that the printer
    happens to belong to my fiance'.

INCOMPATIBILITIES:
    o Some network software use the same interrupt vector and Hiplot2
    will not allow loading.  If you network, try not installing the
    network software prior to plotting to your printer.

    o As I said, the Star Radix-15 skips lines.

                                  Rolodex


         The  Rolodex  program is very limited. It was created simply
     to  be  a  computerized  Rolodex.  It only keeps track of names,
     addresses, zip codes, and phone numbers.

         The  first  time  the program is run, it will give a message
     about  the program's data file. The data file is very large, and
     doesn't change size as more addresses are added. For this reason
     it  is suggested that you have only DOS, BASIC, ROLODEX, and its
     data file on the disk.

         The  program  seperates  the data file into 26 sections much
     the same as a rolodex would, with one section for each letter of
     the alphabet. The maximum number of addresses is around 800. The
     program  doesn't  check  to  see  how  many  addresses there are
     because this would slow it down alot.

         Inputting  names  and  addresses is fairly straight forward.
     After  the  lights and music have died (you can delete it if you
     want,  I  just  get a kick out of seeing my own name) you choose
     the  A  option  and  enter  the data with an enter at the end of
     each.  The  only thing the program has to have, is a letter (A -
     Z)  as  the  first  character of each last name. Everything else
     doesn't  really matter. You don't even have to put number in for
     the phone number.

         The  rolodex  also has a built in Sub Code, which means that
     you  can  store several mailing lists in the same data file. For
     instance, you could store a list of clients with a sub code of C
     and  a  list  of  relatives  with a sub code of R. Then when you
     wanted  to  address  for  clients,  just  use the option to list
     according to sub code and choose either C or R.

         The  zip  code is large enough to hold the new zip codes, or
     even  a Euoropean Post Code. The phone number is large enough to
     hold  two seven digit numbers, or 1 long distance number. It can
     even hold a full European number.

         The page-up and page-down keys have function in a few areas.
     It  is  best  to just experiment with these and see exactly what
     they do. It is always harmless to press them.

         Any  time that the program needs to search for a record, you
     will be asked for the last name. You may either enter the entire
     last  name,  or  a part of it. But if you enter a part of it you
     must  put a question mark at the end. Thus to search for someone
     with the last name of Jones, you could search for Jones, Jones?,
     Jone?, Jon?, Jo?, or J?. As you must expect, the first character
     must  be  a letter. Also note that if you type J? you will get a
     list  of  every  person  whose  last  name  starts  with J. Also
     searching  for  Jo?  could  get  Jones,  Johnson,  or  any other
     starting with Jo.

         If  more  than one person qualifies in your search, you will
     be  shown  a numbered list of the people and asked which one you
     were  after.  If  you want none of them, a blank return will get
     you  out.  Also, if you are editing a record, hitting the return
     without  typing  anything over the previous data will leave that
     data unaltered.

         As for printing out the names and addresses, the program has
     been  set up to print standard mailing labels. It would print an
     address  every  6  lines. You always have the option of printing
     the phone number or not.

         You  can  easily  add to the program in any way you care to.
     You  could  easily  put  in  routines  to be sure that names are
     printed  in alphabetical order. It would be a little more tricky
     to put them in zip code order, but it is possible.

             Schedule.bas   allows you to set  and  organize your  appoi-
        ntments   or activities that you want to do.  You can write  your
        appointments  or  activities for the whole year.  There  is  room
        provided for each day of the year.  Each day can hold your  acti-
        vities from 6 o'clock in the morning till 10 o'clock at night for
        each half hour.

        REQUIREMENTS:

                      Double sided disk.  color graphics card (see  below
                      for monochrome card modification)

        RECOMMENDDED HARDWARE:

                      2 double sided drives, or a drive and a harddisk

        HOW TO BEGIN USING THIS PROGRAM:

                      Because  of  the  large file needed  to  hold  this
                      immense amount of  data, you need an empty diskette
                      to hold the 289k file created.  The  program  works
                      best on a 2 disk drive system.

              If You Have 2 Disk Drives:

                      -Save the program on a diskette at drive A (usually
                      along with your other Basic Programs.)

                      -Put an empty formatted disk on drive B.

                      -Load BASICA. (BASICA is supposedly on drive a)

                      -Load SCHEDU.BAS and run it.

              The program assumes that the data file SCD is on drive B

              If You Have One Disk Drive

                      -Modify line 100 into: 100 DRIVE$="A:"

                      -Load BASICA

                      -Load SCHEDU.BAS

                      -Remove  your diskette and put an  empty  formatted
                      disk on the drive.
                      -Run the program SCHEDU.BAS

              Needles  to  say,  you only format the diskkette the  first
              time you use the program,  or you will erase your data each
              time you format it.






                                        2








        HOW TO USE THIS PROGRAM:

                      Upon  running the program,  you will see the  first
                      screen of the program.  You can select any of the 8
                      options  you have.  But before doing anything,  you
                      must initalize your data file. This  can  be easily
                      accomplished by choosing option #3.  Remember  that
                      you only have to do this the first time you use the
                      program. If there are any data in the data file, it
                      will  all  be erased.  After initalizing  the  data
                      file,  you  can choose any of the options from 1 to
                      8.  initalizing the file is a process that takes  a
                      long  time to complete,  but you only need to do it
                      once.

        EXPLANATIONS OF THE 8 OPTIONS:

        OPTION 1:
                      Allows you to see the activities that you scheduled
                      some time ago. When you strike 1, you will be asked
                      to enter the month name (not the month number)  and
                      the  day at which you want to  see  the activities.
                      Note that you do not have to type the whole name of
                      the month.

        Example:
                      If  you want to  see  the activities  scheduled  on
                      the 5th of april,  you enter the letter A,  then P.
                      The  program will assume that you wanted  to  enter
                      april,  so it will directly prints april,  and then
                      asks  you for the  day.   Now type 5,  then  strike
                      (ENTER.)   If   you  wanted   to   select   another
                      month,  say december,  enter 0 at  the  "Which day"
                      prombt. Now you press d and the program will assume
                      that  you  wanted to enter the month december.  The
                      Last  line at the bottom always displays  your  op-
                      tions along with some suggestions.

              After  the program displays the activities scheduled at  the
              specified date, you have the options to:


                      -See the activities of the next day by pressing the
                      Pg Dn key

                      -See  the activities of the day before by  pressing
                      the Pg Up key


                      -Write activities by pressing W (see option 2)

                      -Go to the main screen by striking any other key.





                                        3








        OPTION  2:
                      Allows you to write activities.  After entering the
                      month  and the day,you will see a  menu  displaying
                      the  activities scheduled for the specifyed date if
                      any.  You  will see the time 6:00  highlighted.  To
                      write an activity,  select any time of that day  by
                      pressing  the up or down arrow,  then press  ENTER.
                      Now  type your activity( up to 25 characters only).
                      When finished,  press ENTER. Now the next TIME will
                      be automatically highlighted.  if you want to write
                      activity at this time,  press ENTER and repeat  the
                      procedure, otherwise choose the appropriate time.

              These  are  the options that you have during  this  writing
              mode:

                      -Up and Down arrow:  Allows you to select the  time
                      at which you want to write your activity.

                      -End:  Saves  your  activites and takes you to  the
                      main screen.

                      -R  :  Switches you to the Reading  mode.  This  is
                      helpful  when you want to see or write at the  next
                      or the preceeded day.


        Note:

                      1-Those above options can not be selected while you
                      are typing an activity.

                      2-You  can  not write directly to the next  or  the
                      preceeded day. You must first switch to the Reading
                      Mode  by pressing R,  and then use the Pg Up or  Pg
                      Dn, then switch to the Writing Mode by pressing W.

                      3-Pressing  ENTER  after writing at the  time  1:30
                      will  not automatically takes you up to 2:00  time.
                      Press the Down key to go there.

                      4-When  you  are  writing an  activity,  the  input
                      control is handed to the BASICA  interpreter.  You,
                      therfore  have  to be careful in using the  editing
                      keys,  since you may accidentally disturb the  data
                      displayed   on   the  screen.   It  is   therefore,
                      recommended  that  you only use the  left  and  the
                      right arrow when writing an activity.

                      5-The WRITING mode can be accessed by either  stri-
                      king  2 at the main screen,  or striking W when  at
                      the READING mode.





                                        4








        OPTION 3:
                      Allows you to innitlize the data file:  This should
                      be done the first time you use the program.  inita-
                      lizing the 9000 records contained in the data  file
                      takes   a   long  time  to complete.  A  beep  will
                      indicate that the initialization is  complete.

        OPTION  4:
                      Changes  the default drive at which the  data  file
                      resides.

        OPTION 5:
                      Clears part of data. Suppose that you want to erase
                      all  the activities during a certain   period.  You
                      select the date this period begins, and the date it
                      ends.  A  beep  will indicate that the  erasing  is
                      finished.

        OPTION 6:
                      Add  a  constant  occuring activity for  a  certain
                      period of time.   This is helpful if there are some
                      activities that you do every day.  For  example you
                      may want to assign to time 6:00 the activity  (WAKE
                      UP.) or assign at time 12:00 the activity (LUNCH.),
                      and so on.

        OPTION  7:
                      Print A Certain Day Schedule.  This option prints a
                      certain day schedule,  supporting the I.B.M/Epson's
                      dot matrix printers.

        OPTION 8:
                      Ends  the  program.  Pressing Esc will do the  same
                      thing.

        UNDOCUMENTED FEATURE:

                      Pressing   PgUp  at the Main Screen will  show  the
                      last screen you  have  just exited.  PgDn will  re-
                      turn  you  back  to the Main screen.  This  may  be
                      helpful if you have just got out of a  screen,  and
                      decided  to glance on it after you got to the  main
                      screen


        IF YOU HAVE THE MONOCHROME CARD:

                      Modify the program by erasing the SCREEN functions,
                      and  modify line 140 so that check=0.  This can  be
                      easily achieved on your word processor,  using  the
                      search  and replace functions.All the graphics done
                      on the screen is done using the 255 characters that
                      are  supported by the the monochrome and the  color
                      card.

        IF YOU HAVE THE COLOR GRAPHICS CARD:

                      If you have a color monitor,  play around with  the
                      COLOR  function  to set the colors you  prefer.  Be
                      aware that there is a lot of highlighting and video
                      reversing.  The Search and Replace function in your
                      word proceesor will be of a great help. If you have
                      a  white and black monitor like me,  well,  you are
                      lucky  'cause you do not need to modify or set  any
                      color.

        GENERAL NOTES:

                      -The  diskette that contains the data  file  should
                      not contain any other files.  There is just no room
                      for any other file unless you are running DOS2.?

                      -The  program   does not check to see if  your  day
                      falls  on  the month you specify or  not.  If,  for
                      example you specified april, 31 to write your acti-
                      vities,  your  data will be saved  under  may,  1st
                      because april is 30 days long.

                      -Each  year,  line 896 should be changed to reflect
                      the  current year.  The default value is  the  year
                      1984.

                      -Running the Program under BASICA is required.

                      -Any  one  is welcomed to compile  the  program  or
                      improve it,  then upload it again to the Compuserve
                      software library.
                      -Send your comments,  bug findings,  or suggestions
                      via EMAIL.
