PCjs Machines

Here are three programs for system enhancement: 1) the Datamorphics
Screen package for greater display control, 2) PC-COMPARE for comparing
data files and; 3) DEFKEY, a keyboard reassignment program simular to
Prokey.  All of these programs can be quite helpful in streamlining and
simplifying your daily operations.

System Requirements:  Some programs require a version of BASIC

How to Start: Consult the .DOC and README files for directions and
documentation.  To run the BASIC programs, consult the directions in
GETTING STARTED for your configuration.  To run any of the programs
with the suffix .COM or .EXE, just type its name, i.e., for
COMPARE.COM, type COMPARE and press <ENTER>.

System
Requirements: IBM PC with PC-DOS, or a compatible system;
              MONOCHROME or COLOR/GRAPHICS board and 80 column display;
              128k of RAM memory minimum to run the program;
              a single- or double-sided disk drive and/or hard disk.
              IBM/Epson or compatible printer for a printout.

 Recommended: A printer Spooler/Buffer program installed in RAM if your
              system has more than 128K of main memory. Otherwise, the speed
              of the comparison will be slowed by the printer buffer alone.

        NOTE: A tradeoff exists in overallocating RAM for a printer buffer
              and therefore decreasing the amount of free RAM available for
              the comparison, since both files to be compared are read in
              completely at the beginning of the comparison.

                                for the IBM PC                   screen 3.


    If you send the output directly to your line printer, you are asked if
the printer is in the condensed mode. (i.e., 132 characters per line). Type
"N" if you're not sure, But if so, type "Y" and compare lines longer than 132
characters will be truncated. Otherwise the truncation will be for any line
longer than 80 character. The default for line truncation to an output disk
file, or to the screen - if you are displaying the search line - is also 80
characters. The default printer port is LPT1. Use MODE to change it.


    A NOTE ON PROGRAM PHILOSOPHY: when a mismatch occurs between two compared
lines, the first file read in becomes `fixed' at the first mismatch line and
the second file is incremented and compared to the first file, line by line,
to the LookAhead value, until a match occurs or to the end of the file, if
this is less than the LookAhead value. If no match occurs, the first file is
incremented one line, the second file is set to its last starting point plus
one line and, again, the second file is incremented line by line to the Look-
Ahead value or until a match is found. This repeats until there is a match or
until an end-of-file for one or both of the files is reached.


                          P C - C O M P A R E  ver 1.30
                                for the IBM PC                   screen 4.


    The LookAhead parameter refers to the number of lines the second file is
scanned ahead while holding the first file at a mismatched line. Hit ENTER
to use the default LookAhead value of 40 lines. The maximum allowed is 255.
Displaying the file line being searched for is also an option.


    A WORD OF CAUTION: If the first file line number gets ahead of the second
file, a match is often unlikely. This means the LookAhead parameter wasn't
set to a high enough value. Use the ESCape key to end the compare and restart
with a larger LookAhead value, any value up to 255.


    Since the first file is held and the second incremented, the file which has
fewer and/or deleted lines should be read in first, or the file with added
lines second, to decrease the compare time. Otherwise, the `fixed' file will
increment past these additional lines only once per LookAhead value. In other
words, the file with additions should be second.

                                for the IBM PC                   screen 5.



    A CAVEAT: Do not change the initial screen when the program is invoked,
nor the title line and copyright notice on the menu screen. These are
protected; any change(s) will render the program unuseable.


    WHAT IS A MATCH?  When a line of each file is read from memory, leading
and trailing ASCII characters below chr(33) (i.e., a SPACE and below) are
stripped. This means lines with different indenting only will still match.
However, imbedded tabs, spaces, etc., are significant and any differences
between them will cause a mismatch of those two lines. When a line being
searched for is displayed, therefore, it will always be shown left-justified.

    However, this process of `cleaning' leading and trailing spaces, etc, is
ONLY done to the lines in memory, and not to your original on disk. The two
input files remain in their original condition on disk.

                                for the IBM PC                   screen 5.


    This version of the program allows files with lines of up to 255
characters to be read in. This is also true of BASIC program files which have
been saved in BASIC with the ,A option. See your BASIC manual - the `SAVE'
command - for more information on saving your progra as an ASCII file.

NOTE:  There is a 100 line maximum limit for each file. Otherwise it is a
       full-featured version of AUTOCOMP, marketed by:

1) PURPOSE

   The purpose of this program is to allow the user to customize almost
all of the keys ofthe PC's keyboard, provided that PC-DOS Version 2.0 is
being used .  Using this utility, it is possible to assign almost any
string to almost any key or combination of keys (such as ALT-A, etc),
thus significantly decreasing the amount of typing that the user will
have to do.  For example, it is possible to assign the dos command `DIR'
to the ALT-D sequence so that whenever these keys were pressed, `DIR'
would be printed out.

2) STRUCTURE

   The DEFKEY utility is comprised of two seperate files, DEFKEY.BAS and
DEFKEY.BAT.  The batch file allows you to invoke the utility by simply
entering `DEFKEY' to the dos prompt.  This file then goes into BASIC and
executes the DEFKEY.BAS program. After execution of the program is
complete, DEFKEY returns to dos and copies the output file that contains
the new keyboard definitions to the computer's memory by executing the
dos command : COPY DEFKEY.ANS CON: . From this point on, all the new key
definitions will be in effect.

        NOTE : This procedure will not work unless the system file
ANSI.SYS has been placed in the CONFIG.SYS file before the current boot
up.  This can be done by typing the following instructions to the dos
prompt:


                         COPY CON: CONFIG.SYS
                         DEVICE=ANSI.SYS

and then entering CTRL-Z.  Dos should respond with `1 file copied'.
Then re-boot by entering CTRL-ALT-DEL and the ANSI.SYS driver will be
installed in the system thus allowing you to re-define the keyboard.

   It should be noted, however, that this will only allow you to use 128
characters in your definitions.  In order to be able to use more than
this limit, the ANSI driver must be altered. This alteration procedure
is outlined in the November, 1983 issue of PC MAGAZINE (Vol. 2, Number
6) on pages 564 and 565, and is not included here due to its complex and
technical nature.  This notwithstanding, I had no trouble in making this
relatively simple modification.


3) THE PROGRAM ITSELF

   Once the main program has started to execute, you will be asked to
enter the key that you wish to define. At this point a carriage return
or the entering of the word `HELP' will print out detailed instructions.
   The keys that may be defined by this program have been divided
into three catagories.

   First there are the standard keyboard characters: the letters,
numbers, etc. These are signified simply by typing the character that
you wish to define.

   Second are these same characters when part of an ALT sequence as in
ALT-A or some combination like it. This type of sequence is signified by
typing a capital A before the key to be defined. Thus `AB' would signify
the `ALT-B' sequence.

   Last are the special keys or key sequences. The function keys and
such other keys as `HOME', `INS', `DEL' ,etc fall into this catagory. To
define these keys,you must enter the entire key name. You can get a full
list of these special keys by entering a carriage return or `HELP' at
this time.


          NOTE: The function keys are denoted by `FK1' - `FK10'.
                The ALT-FUNCTION KEY sequences are denoted by `aF1'
                - `aF10'.  The `a' MUST be lower-case.
                `CF1' - `CF10' denote the CTRL-FUNCTION KEY sequences, and
                `SF1' - `SF10' denote the SHIFT-FUNCTION KEY ONES.


   After you have entered the key to be defined, you will be asked to
enter a definition.You can get help at this point by entering a carriage
return. A definition may be of two forms. It may be either a simple
string expression such as `have a nice day' or it may be an ASCII code
number. representing a character or other expression.

   To enter a simple string just type in that string.
   To enter an ASCII expression, enter the letters `ASC' followed by the
ASCII code number. For example, you might enter `ASC068' to assign an
upercase `D' to a key, since 068 is the ASCII code for `D'.

   The program will then ask you to define another key. You may define
as many keys as you like, but you should keep in mind that the maximum
number of chatacters that all of your definitions combined may have is
128 unless you have modified the ANSI driver.

   To end, type in `END',`EXIT',`BYE',`DONE' or `STOP' when the
program askes what key you want to define.

4) IMPLEMENTING DEFKEY


   After you exit from the program, you will be returned to dos and the
keyboard definitions which will then be contained in the file
`DEFKEY.ANS' will be copied to the system as described above.  If a
previous `DEFKEY.ANS' file existed at the time the `DEFKEY.BAT' file was
called on, it was renamed to `DEFKEY.BAK'. If `DEFKEY.BAK' also existed,
it was deleted.

   In any case, `DEFKEY.ANS' will now contain the most recent set of key
definitions.  This file must be re copied to the system each time you
boot up for its definitions to be effective.  You might want to include
it in the AUTOEXEC.BAT file so that it will be automatically entered at
boot up.  This may be done by typing the following sequence to dos:


                        COPY CON: AUTOEXEC.BAT
                        COPY DEFKEY.ANS CON:

and then entering CTRL-Z.


                         HAPPY COMPUTING!!!!!



PROGRAM:  TRS Model 100 to IBM PC Text File Transfer



AUTHOR:  Ken Cooper, Ph.D.



PURPOSE:  This simple BASIC program allows the transfer of text

files from the Radio Shack TRS-80 Model 100 Portable Computer to

an IBM PC.  Data is communicated over a direct cable (and null

modem) connection between the standard RS-232 port of the Model

100 and the optional COM1 port of the PC.



BACKGROUND:  As a writer, I use the Model 100 to create text

files while traveling.  I do all my text processing on the PC and

needed a simple program to upload the text for input to VisiWord.

I have no need for a downloading function since VisiWord can

quickly and easily be configured to "print" standard DOS files to

the COM port (with TELCOM running on the Model 100.)  Any program

which can print to a COM port can download in similar fashion.



Rather than purchase an expensive communications program for this

simple application, I used the example in the back of the BASIC

manual to build MOD100IN.bas.  The program transfers data (albeit

slowly) to the PC, building up a text array in storage.  The

available storage in a 64K system is more than adequate for the

program and largest text file possible in a 32K Model 100.  In

addition, the storage array is dimensioned for approximately 30K

of text at a Model 100 transmission blocksize of 120 characters.



USE:  It is necessary to create text on the Model 100 using two

carriage returns between paragraphs.  This allows MOD100IN.bas to

identify the carriage return automatically inserted at the end of

transmission blocks by TELCOM on the Model 100.  Any single

carriage return is edited out of the transmitted text by

MOD100IN.bas, and end-of-paragraph double carriage returns are

reduced to a single carriage return.



Also, due to the programming method used to edit the carriage

returns, the maximum size of a single paragraph of text which can

be transferred is about 220 words.  This corresponds to a typical

full double-spaced typed page.  (If your paragraphs are much

longer than that, no one will want to read what you write

anyway.)



STEP 1:  Connect the RS-232 ports together using an appropriate

cable and null modem.  These are available from most computer

stores and from any Radio Shack computer center.



STEP 2:  Line 100 of MOD100IN.bas described the transmission

protocol to be used by TELCOM on the Model 100:  300 baud, even

parity, 7 data bits, and 1 stop bit.  Set up TELCOM with these

features as described in the Model 100 manual.



STEP 3:  Get into BASICA from the system and LOAD (not RUN)

MOD100IN.bas.



STEP 4:  Follow the procedure for UPloading files in TELCOM as

described in the Model 100 manual.  When you reach the prompt:



         LENGTH = _



type in the value 120 and DO NOT hit return.



STEP 5:  Type RUN on the IBM PC to start MOD100IN.bas running.

You will be given a prompt to hit the return on the Model 100.



STEP 6:  Hit <return> on the Model 100.  The system will appear

to go dead, possibly for some minutes if the file is large.

Using 300 baud is very slow, but BASIC isn't fast enough to keep

up with a higher baud rate.



STEP 7:  When transfer is complete, you will see a status message

on the PC, and will next be asked to input a filename for

storage.  GET THIS RIGHT, including the drive designation where

necessary.  No quotes are needed.  If you make some kind of error

which does not allow the storage operation to complete, such as

trying to store onto a protected diskette, etc., the program will

abort and the entire transfer operation will have to be repeated

from the beginning.



NOTE:  There is no drastic hurry to move from Step 5 to Step 6,

yet there should be little time delay.  BASICA times out after a

few seconds when there is no data input to the COM port and halts

the execution of MOD100IN.bas with an error message.







KNOWN PROBLEMS:



1.  There is a small bug which randomly surfaces when the text

file end falls on an end of transmission character.  (This should

only happen statistically once in every 120 times, based on a

block length of 120.)  When this occurs, merely resend the file

using a different block length such as 119 or whatever to assure

ending on some other position.



2.  There is another small bug which evidently misses removing

occasional transmission carriage returns from the middle of a

paragraph.  I have as of yet found no pattern from which to

develop a fix.  Besides, it is a simple operation to delete the

character from VisiWord (or whatever text processor you use.)



SUMMARY:



This is not a particularly sophisticated program, written by a

programmer of similar skill.  Yet it gets the text file uploaded

adequately for most needs.  The Model 100 makes a great remote

device for text entry, and the PC is perfect for final editing.

I hope you find this program of use.



           =================================================

                              PC-BW V1.0

           =================================================




     Purpose:

     PC-BW is designed for those who use a black and white display
     with the  IBM colour  graphics adaptor  (or equivalent).  The
     program  intercepts  requests  to  `set operational mode' and
     substitutes  the  equivalent  black  and  white mode for each
     colour mode  request. This  will improve  the clarity  of the
     display for many programs which use the colour capability.


     PC-BW works with DOS 1.1 and DOS 2.0, and with the IBM PC and
     the PC-XT.

     PC-BW works with all programs in  your system. It can be used
     in conjunction with any  of the other programs on  this disk,
     and should work with any other program.

     In case of problems with other DOS resident programs, execute
     PC-BW last.   If operation is still  incorrect, please report
     problems to Datamorphics Ltd. at the address given below.


     Installation:

     The distribution disk contains three PC-BW related files:

           -   PC-BW.COM       This   file    instals  the  colour
     modification program in your system.  The program executes as
     an extension to DOS. It is  permanently resident and occupies
     128 bytes of memory. This program works  with DOS 1.1 and DOS
     2.0.

           -   PC-BW.D11        This  file    instals  the  colour
     modification program  in your DOS 1.1 system. It is identical
     to PC-BW.COM except  that it is  further optimised to  reduce
     space required  in your DOS 1.1 system. We assume that if you
     are running  DOS 1.1  then your  memory space  is valuable to
     you. This version occupies only 48 bytes of memory. NOTE THAT
     IT DOES NOT WORK  WITH DOS 2.0. To use this  version, copy it
     to your operational disk and rename it to PC-BW.COM.


           -  PC-BW.DOC      This  file  contains  documentation
     for PC-BW.


     To  use  PC-BW,  we  suggest  that  you  copy  PC-BW.COM  (or
     PC-BW.D11) to your DOS disk.

     PC-BW should be executed only once per session, usually  just
     after the system is booted.


     Operation:

     PC-BW.COM  should only  be executed  once, usually just after
     the  system  is  booted.  It  can  be  incorporated  in  your
     AUTOEXEC.BAT file, if desired. On execution, the program will
     be made resident above DOS:

                       A>pc-bw



     Payment:

     This subsystem is one  of three on the distribution diskette.
     If you  find this, or  any of the  others, to be  valuable on
     your  personal computer,  please submit  a payment  of $20.00
     together with your name and address to -


                          Datamorphics Ltd.,
                             P.O. Box 820,
                             Stittsville,
                               Ontario,
                            Canada K0A 3G0.


     Registered  users will  be kept  informed of  updates and new
     software available from Datamorphics Ltd.

     Regardless of whether you decide to pay for this program, you
     are encouraged  to copy the distribution diskette and pass it
     on  to  friends  and  associates,  provided  only  that   you
     distribute the complete contents  of the diskette, and do not
     modify the  programs or  charge for  distribution (except for
     diskette costs).


     User Supported Software:

     This  program  is   part  of  the  User   Supported  Software
     experiment. Its objectives are:

       1.   To  permit  users  to  evaluate  a software package at
     leisure on their own  systems before deciding whether  or not
     to purchase it.

       2.   To  offer  an  alternate  means of  distribution which
     benefits both user and publisher: The publisher benefits from
     low distribution and advertising costs. This saving is passed
     on  to  the  user  in  two  ways  -  a  lower  price; and the
     availability of small  packages which could not  be published
     cost effectively through traditional channels.

       3.   To  provide a means  of  software  distribution  which
     encourages  rather  than  restricts  the  copying  and casual
     distribution of programs. This distribution system we believe
     to   be  more  suited  to  the  electronic  medium  than  the
     traditional systems which seek to restrict access to software
     packages.


     To Obtain a Copy of PC-BW:

           =================================================

                             PC-Page  V1.0

           =================================================




     Purpose:

     PC-Page prevents  the annoying  habit many  programs have  of
     scrolling information up and off the screen before you have a
     chance to read it.

     PC-Page breaks  long streams of output  into readable `pages'
     and waits for a keystroke between pages, thus allowing you to
     view information at your own pace. A `page' can be any number
     of lines between 2 and 100, and is set by the `Page' program.
     In practise, most people will find page lengths  of around 20
     to  25  most  convenient.  PC-Page  can  also  be placed in a
     dormant mode in which it will not affect the output stream.

     PC-Page  will  not  interfere  with  short  bursts  of output
     interspersed with input from the keyboard. PC-Page works with
     all programs, including BASICA and BASIC programs.

     Paging does not  have to be specified with  every command you
     enter.   Once installed, you  only need to  enter commands to
     change  the  page  size  you  are  working  with - `paging is
     automatic for every program executed.

     PC-Page works  with DOS 1.1 and DOS 2.0,  and with the IBM PC
     and the PC-XT.

     PC-Page  works with all programs in your system. If it should
     interfere with  the natural  operation of  your program, just
     place  it in the  dormant mode (see  below). For example, you
     will  find  PC-Page  to  be  useful in conjunction with TYPE,
     BASICA, and DEBUG.

     PC-Page  should  be   compatible  with  other   DOS  resident
     programs, and can be used in conjunction with either  or both
     of the  other subsystems  on this  disk. In  case of problems
     with  other   vendor's  programs,  instal  PC-Page  last.  If
     operation is  still incorrect,  please report  the problem to
     Datamorphics Ltd. at the address below.


     Installation:

     The distribution disk contains four PC-Page related files:

           -  PC-PAGE.COM      This  file  instals PC-Page in your
     system. The program  executes as an  extension to DOS.  It is
     permanently resident and occupies  320 bytes of memory.  This
     program works with DOS 1.1 and DOS 2.0.

           -  PC-PAGE.D11       This file  instals PC-Page in your
     DOS 1.1 system. It is identical to PC-PAGE.COM except that it
     is further optimised to reduce space required in your DOS 1.1
     system. We assume that  if you are running DOS  1.1 then your
     memory space is  valuable to you. This  version occupies only
     272 bytes of memory. NOTE THAT IT DOES NOT WORK WITH DOS 2.0.
             To use this version, copy it to your operational disk
     and rename it to PC-PAGE.COM.

           -  PAGE.COM         This  program  is  used  to set the
     `page' size. Any page  size from 2 lines to 100  lines can be
     used. Also,  specifying page size  0 will place  PC-Page in a
     dormant mode in which it will not affect the output stream.

           -  PC-PAGE.DOC      This  file  contains  documentation
     for PC-Page.


     To  use  PC-Page,  we  suggest  that you copy PC-PAGE.COM (or
     PC-PAGE.D11) and PAGE.COM to your DOS disk.

     PC-PAGE should  be executed  only once  per session,  usually
     just after the system is booted. The PAGE program is executed
     each time you want to change `page' size.



     Operation:

     PC-PAGE.COM should only be executed once, usually  just after
     the  system  is  booted.  It  can  be  incorporated  in  your
     AUTOEXEC.BAT file, if desired. On execution, the program will
     be made resident above DOS. Initially, the paging function is
     dormant:

                       A>pc-page

     To set or change the `page' size, use the PAGE command with a
     page length specification:

                       A>page 24

     will set the  `page' size to 24 lines. Setting `page' size to
     0 will make PC-Page dormant again:

                       A>page 0
     or
                       A>page

     When operational, the paging software will break long streams
     of output after the number of lines you specify, and output a
     prompt `Hit any key to continue . . .' Output will then pause
     until you  enter a character  at the keyboard.  Note that the
     character will not be passed to the program executing.
     Entering the `Control-Break'  sequence will end the pause and
     will pass `Control-Break' to the program executing.


     Payment:

     This subsystem is one  of three on the distribution diskette.
     If you  find this, or  any of the  others, to be  valuable on
     your  personal computer,  please submit  a payment  of $20.00
     together with your name and address to -


                          Datamorphics Ltd.,
                             P.O. Box 820,

                            Canada K0A 3G0.


     Registered  users will  be kept  informed of  updates and new
     software available from Datamorphics Ltd.

     Regardless of whether you decide to pay for this program, you
     are encouraged  to copy the distribution diskette and pass it
     on  to  friends  and  associates,  provided  only  that   you
     distribute the complete contents  of the diskette, and do not
     modify the  programs or  charge for  distribution (except for
     diskette costs).


     User Supported Software:

     This  program  is   part  of  the  User   Supported  Software
     experiment. Its objectives are:

       1.   To  permit  users  to  evaluate  a software package at
     leisure on their own  systems before deciding whether  or not
     to purchase it.

       2.   To  offer  an  alternate  means of  distribution which
     benefits both user and publisher: The publisher benefits from
     low distribution and advertising costs. This saving is passed
     on  to  the  user  in  two  ways  -  a  lower  price; and the
     availability of small  packages which could not  be published
     cost effectively through traditional channels.

       3.   To  provide a means  of  software  distribution  which
     encourages  rather  than  restricts  the  copying  and casual
     distribution of programs. This distribution system we believe
     to   be  more  suited  to  the  electronic  medium  than  the
     traditional systems which seek to restrict access to software
     packages.


     To Obtain a Copy of PC-Page:

     If  you would like a copy of  PC-Page, but do not have access
     to  it  via  a  friend  or  acquaintance,  the   program  and
     documentation  can be  obtained from  the above  address upon

           =================================================

                              PC-TTY V1.0

           =================================================




     Purpose:

     PC-TTY  modifies  the TTY emulation mode  provided by the DOS
     BIOS  routines. It implements two changes in the operation of
     TTY emulation:

           1.     The  program enables  you to  edit lines  longer
     than 80  characters  using  the  standard  DOS  line  editing
     functions. The change also corrects a problem in the ROM BIOS
     which causes an  additional blank line to be  inserted in the
     output stream following a line of exactly 80 characters.

           2.     The program provides the option to `wrap' or not
     to `wrap' lines which are greater than the screen width. BIOS
     provides  `wrap' as standard  - i.e. a  line greater than the
     screen width is displayed by continuing it on the  line below
     (it is `wrapped' around onto the next line). The alternative,
     which  is  sometimes  more  useful,  is  not  to  display any
     characters of the line which  extend beyond the screen width.
     This mode ensures  that the screen  will always display  (the
     first 40 or 80 characters of) 25 lines of the source file.

     PC-TTY   will  not  interfere  with  any other aspect of  the
     screen display.

     Once installed, the wrap mode is changed by using  the `WRAP'
     command.

     PC-TTY  works  with DOS 1.1 and DOS 2.0,  and with the IBM PC
     and the PC-XT.

     PC-TTY   works with all programs in your system. With  `wrap'
     set  ON  (the  default),  the  system will operate exactly as
     before, except  that the problem with 80 character lines will
     not occur, and line editting will be improved.

     PC-TTY can be used in conjunction  with either or both of the
     other  two  subsystems  on  this  diskette. It should also be
     compatible  with  other  DOS  resident  programs.  In case of
     problems,   instal  PC-TTY   last.  If   operation  is  still
     incorrect, please report the problem to  Datamorphics Ltd. at
     the address given below.


     Installation:

     The distribution disk contains four PC-TTY related files:

           -   PC-TTY.COM       This  file  instals PC-TTY in your
     system. The  program executes as  an extension to  DOS. It is
     permanently resident  and occupies 384 bytes  of memory. This
     program works with DOS 1.1 and DOS 2.0.

           -  PC-TTY.D11      This file instals PC-TTY in your DOS
     1.1 system. It is identical  to PC-TTY.COM except that it  is
     further optimised  to reduce space  required in your  DOS 1.1
     system. We  assume that if you are  running DOS 1.1 then your
     memory  space is valuable to  you. This version occupies only
     304 bytes of memory. NOTE THAT IT DOES NOT WORK WITH DOS 2.0.
     To  use this  version, copy  it to  your operational disk and
     rename it to PC-TTY.COM.

           -   WRAP.COM         This  program  is  used to set the
     `wrap'  mode. `WRAP  ON' is  the default  and implements only
     feature  (1)  above.  `WRAP  OFF'  inhibits line wrapping and
     ensures that the  display will show  25 lines of  your source
     file.

           -  PC-TTY.DOC      This file contains documentation for
     PC-TTY.


     To  use  PC-TTY,   we  suggest  that you copy PC-TTY.COM (or
     PC-TTY.D11) and WRAP.COM to your DOS disk.

     PC-TTY should  be executed  only once  per session,  usually
     just after the system is booted. The WRAP program is executed
     each time you want to change `wrap' mode.



     Operation:

     PC-TTY.COM should only  be executed once, usually  just after
     the  system  is  booted.  It  can  be  incorporated  in  your
     AUTOEXEC.BAT file, if desired. On execution, the program will
     be made  resident above DOS. Initially,  the wrap function is
     enabled (as in standard DOS):

                       A>pc-tty

     To set or change the `wrap' mode, use the WRAP command with a
     mode specification:

                       A>wrap on
     or
                       A>wrap

     will  set the  `wrap' function  on (default).  Setting `wrap'
     mode off will prevent long lines from wrapping around onto  a
     second  line of  your screen.  Instead, extra characters will
     not be displayed:

                       A>wrap off

                      PROGRAM DESCRIPTIONS


DEFKEY.BAS       - A BASIC  program that allows the user to
                   totally re-define the dos keyboard.

DEFKEY.BAT -     - A batch file that allows you to run DEFKEY.BAS
                   by simply typing `DEFKEY' to dos.  This file
                   also copies the output file which DEFKEY.BAS
                   creates to the system, thus activating the
                   re-defined keys.

KEYS.BAS         - A BASIC program that re-defines the BASIC
                   function keys and allows you to load to specify
                   a program to be run.

BASICAK.BAT      - Loads BASIC and runs KEYS.BAS from dos.



         These programs were created by Charlie Tomberg

	   *** THIS WILL BE A SAMPLE TEXT FILE TO COMPARE ***

    This program allows you to compare two ASCII/text files - though not
files in binary code; use COMP.COM on your DOS disk for this - and list their

differences to the printer or to a disk file. The file saved on disk can later
be copied to the printer with the `COPY filename PRN' command. The default
output filename is COMPARE.DTA, and is sent to the default drive. If it
already exists, a prompt to overwrite it or for another name, will be requested.
This can be prefixed with a drive letter.

    You can type in the names of the files to be compared on the command
line when the program is called, as; COMPARE filename.one, filename.two, and
hit ENTER key. Use a space or comma to separate the two filenames. Otherwise,
you will be prompted from with the menu screen for the filenames if you

     The LookAhead parameter refers to the number of lines the second file is
key to use the default LookAhead value. The maximum value allowed is 255.

     Printing out the file line being searched for in the second file is also
an option. The `fixed line' option is explained in the next paragraph.

    Again, this program is placed in the user-supported software market on an
"AS-IS" basis, and NO guarantees or warranties accompany it as to its use or
suitability for any application. The "FreeWare" market seems to be missing
a source compare program. This program is released to the public domain
in that spirit. Any financial support is appreciated, of course. But pass
the program along, use it, and comment on it if you wish. Those supporting it
will be informed of any updates or modifications.
