                                      OVERVIEW

         SurveySoft Version 3.0 is the latest version of a  tested  package
         of  surveying  software  adapted  for  the  IBM-PC  and compatible
         systems.  It incorporates  nearly  all  of  the  improvements  and
         modifications  suggested  by  users of Version 2.0,  together with
         several other improvements made  possible  by  a  new  programming
         environment.  Experienced  users  will find the speed of access to
         and execution of nearly all functions to  be  radically  improved;
         beginners  will  find the on-screen prompts to be clearer and more
         useful.

         A more particular  list  of  modifications  incorporated  in  this
         version may be found at the end of this manual.

         Following  is  a list of available SurveySoft functions,  which is
         furnished for quick reference.  (Note that function keys shown  in
         the  form  <ALT><F1>  are  accessed by pressing <F1> while holding
         down the <ALT> key, just as if you were using <ALT> like the shift
         key on  a  standard  typewriter.  Keys  shown  as  <CTRL><F1>  are
         accessed using the <CTRL> key similarly.)

                                INSTALLING DOS SYSTEM

         Experienced  Version  2.0 users -- or any other impatient types --
         may feel free to skip this section for the  time  being.  Just  be
         sure  that you have safely backed up the distribution copy of your
         disk before proceeding to "FOR ALL  USERS"  at  the  end  of  this
         section.

         The  object  of  this  section is to create a disk with all of the
         SurveySoft  files  and  with  the  DOS  operating  system  on  it,
         providing  you  with  a  working  copy which may be used while the
         original is kept safely stored away,  and which  may  be  used  to
         start up your system without the need for your DOS diskette.

         SurveySoft  is  not copy-protected.  Keep the write-protect tab on
         the distribution diskette, don't physically abuse it,  and you may
         make  as many copies as you like (for your own use,  of course) as
         long as the software will be in use on  one  system  only  at  any
         given  time  --  see  the  licensing  agreement  elsewhere in this
         manual.

         SYSTEMS WITH TWO DISKETTE DRIVES.  Insert  your  DOS  diskette  in
         drive A: and a blank diskette in drive B:. (It isn't necessary for
         the disk in drive B: to be blank, of course, but what we are about
         to  do will wipe it clean,  so choose it with care.) If necessary,
         start your system,  enter the date and  time,  and  do  any  other
         necessary housekeeping.  Then,  in response to the A> prompt, type
         FORMAT B:/S and press <ENTER>.  You will be prompted to insert the
         disk to be formatted in drive B:  and press any  key  when  ready.
         Verify that you have done so, then press any key.  The drives will
         operate  briefly  as  the  diskette is formatted and the operating
         system is transferred.  When the process is complete, DOS will ask
         "Format another?  Y/N".  Respond by pressing N.

         When you have the A> prompt once more, remove the DOS diskette and
         replace it with the SurveySoft distribution  diskette.  Type  COPY
         *.*   B:   and   press  <ENTER>.   Each  file  on  the  SurveySoft
         distribution diskette will be transferred to the disk in drive B:,
         which has now become your  working  copy.  Label  it,  remove  the
         distribution copy from drive A: and put it in a safe place, insert
         the  working  copy in drive A:,  and proceed to "FOR ALL USERS" at
         the end of this section.

         SYSTEMS WITH HARD  DISKS.  The  following  installation  procedure
         assumes  that the DOS operating system is already resident on your
         hard disk,  and that your hard disk is drive C:.  A  list  of  the
         files  on  the SurveySoft diskette that will be copied to the hard
         disk follows.  If any files by these names currently exist on your
         hard disk, they will be overwritten and lost,  so you will want to
         consider  renaming  them  before  proceeding.  (See your operating
         system manual for instructions on how to do so.)  Also  note  that
         SurveySoft does add an extension of ".DAT" to all data files,  and
         that DOS 2.0+ pathnames are not supported at this time.


                          SURVEY.COM              SETDRIVE.COM
                          SURVEY.000              DRIVFILE.PAS
                          SURVEY.001              TESTTEST.TST

                          SURVEY.004
        


         Ready?  Insert the SurveySoft distribution diskette in a  diskette
         drive,  make  that drive the default drive,  and type COPY *.* C:.
         (Remember that we're assuming your hard disk to be drive  C:,  and
         substitute the actual name of your hard disk if necessary.)

         When  you  have  the DOS prompt once more,  make the hard disk the
         default drive again, store the SurveySoft distribution diskette in
         a safe place,  and proceed to "FOR ALL USERS" at the end  of  this
         section.

         SYSTEMS  WITH ONE DISKETTE DRIVE ONLY. Insert your DOS diskette in
         drive A:.  If necessary,  start your system,  enter the  date  and
         time,  and do any other necessary housekeeping.  Then, in response
         to the A> prompt,  type FORMAT /S and press <ENTER>.  you will  be
         prompted to put the disk to be formatted in drive A: and press any
         key  when  ready.  Remove  the  DOS  diskette  from  the drive and
         replace it with a blank one,  then press any key.  The drive  will
         operate  briefly  as  the  diskette is formatted and the operating
         system is transferred.  When the process is complete, DOS will ask
         "Format another?  Y/N".  Respond by pressing N.

         When you have the A> prompt once more,  remove the blank  diskette
         and  replace  it  with the SurveySoft distribution diskette.  Type
         COPY *.* B: and  press  <ENTER>,  then  follow  the  disk-swapping
         instructions  provided  by  the  operating  system.  When you have
         finished,  each file on the SurveySoft distribution diskette  will
         have been transferred to the blank diskette,  which has now become
         your working copy.  Label it,  replace it in the  diskette  drive,
         and store the distribution copy of SurveySoft in a safe place.

         FOR  ALL  USERS.  You  should  now  have  your new working copy of
         SurveySoft stored on the default drive and have the DOS prompt for
         that drive on your screen.  To access the  surveying  programs  on
         the  disk,  type  SURVEY  in  response to the DOS prompt and press
         <ENTER>.


                                   GETTING STARTED

         THE OPTIONS MENU. If you have not already done so,  bring  up  the
         DOS prompt and,  with SurveySoft in the default drive, type SURVEY
         and press <ENTER>.  After a few moments,  the  Options  menu  will
         appear  on  the screen.  From this menu you will make a few simple
         choices that will adapt SurveySoft to  your  personal  preferences
         and  to  your  system.  You  may return to this menu from the main
         program and revise your choices any time that you like.

         Your screen should now look something like Figure A.  Whenever you
         load SurveySoft,  the Printer Status and Zenith Input will default
         to "OFF" and Keyboard Audio will default to "ON".  If you elect to
         change  these  values,  you  must  do  so  whenever you reload the
         software.   The  selection  for  the  data  drive,   however,   is
         permanently  recorded  and becomes the new default value until you
         elect to change it again.

         PRINTER STATUS. Set Printer Status to "ON" only if a line  printer
         is  connected  to your system and ready to operate.  If you do set
         the Printer Status to "ON",  SurveySoft will verify that a printer
         is  present  and on line.  If it does not encounter a printer,  it
         will automatically reset printer status to "OFF" and return you to
         the Options Menu.  While in many cases a printed  record  of  your
         activity is desirable, you should be aware that with most printers
         SurveySoft  will  run  very  considerably  slower with the printer
         option selected.

         ZENITH ANGLE INPUT. Your selection of a Zenith Input setting is  a
         matter  of  personal preference,  the type of input with which you
         will be dealing, and the quality of your field notes.  With Zenith
         Input "ON",  every time that SurveySoft prompts  you  to  input  a
         distance,  it will prompt you to input a zenith angle.  As you can
         see,  if you are entering data from a deed  or  plat,  this  could
         become  quite  an  inconvenience.  It  is for this reason that the
         default setting for Zenith Input is "OFF".  (Note also  that  even
         with Zenith Input "ON", you may enter a zenith angle of 90 degrees
         by simply pressing <ENTER> when prompted for the angle.)

         KEYBOARD  AUDIO.  Once  again,  your  choice  of  a Keyboard Audio
         setting is a matter of preference and the environment in which you
         will be using your software.  While the Keyboard Audio setting  is
         "ON",  SurveySoft will chirp (discretely, of course) upon positive
         data entry and input  errors.  If  you  or  others  in  your  work
         environment find this objectionable, you will want to set Keyboard
         Audio to "OFF".

         ACTIVE  DATA DRIVE. As noted earlier,  your choice of a data drive
         is permanently recorded and will  become  the  new  default  value
         whenever  the system is loaded -- although it may,  of course,  be
         changed at any time.

         If yours is a single-drive system, you will want to leave the data
         drive set to A:.  This will mean that all of  your  data  will  be
         stored  upon  your  SurveySoft  working  diskette,  but  since the
         software is not copy-protected,  this should present no particular
         problem.

         If yours is a two-drive system, you will probably want to keep the
         SurveySoft diskette in drive A:  and let drive B:  be the drive in
         which you place your data diskette.  To do so,  press the '+'  key
         once; your display should now show that the data will be stored in
         drive B:.

         If you have a hard-disk system,  you will probably want your data,
         as well as the SurveySoft applications programs to reside on  your
         hard disk.  Simply press the '+' and '-' keys until your hard disk
         drive appears on the display.

         When you are satisfied with your selections from this menu,  press
         <ENTER>.

         Note that if you have changed the data drive, SurveySoft will test
         the status of that drive before proceeding.  If it is unavailable,
         an error message will be displayed and the data file will be reset
         to its previous value.  Note also that if for any reason (such  as
         moving to a new system) the data drive of record is not available,
         the  utility  program SETDRIVE is provided to reset the data drive
         without entering SurveySoft.


         THE MAIN MENU. After you have left the Options  Menu  by  pressing
         <ENTER>,  your  screen  will  display  the  SurveySoft  Main Menu,
         through which all of the software's other features  are  accessed.
         Your display should now resemble Figure B.


                             COORDINATE GEOMETRY PROCEDURES

                                    AN INTRODUCTION.

         All  of  SurveySoft's  various  functions  are  inter-related and,
         unlike many other surveying software packages,  all share a common
         system  of coordinate points.  In the off-the-shelf version of the
         software,  these points may be assigned numbers from  1  to  1000.
         For  most  applications,  this  provides a good working compromise
         between capacity, execution time, and memory demands.


         (If your application demands more storage, and your system is able
         to support it, custom versions of SurveySoft with greater capacity
         are available to current users at a nominal charge.)


         In such a thoroughly integrated program,  many functions make  use
         of data which has already been input by means of others.  Although
         the adventurous user may want to strike out on his own, relying on
         on÷screen  prompts  and  the  list  of functions already provided,
         there follows a tutorial which will take you through  all  of  the
         coordinate  geometry functions provided,  using a simulated survey
         to provide the data.  Functions are  presented  in  the  order  in
         which  they  might  typically  be  used,  beginning with the Field
         Traverse routine.

                                    FIELD  TRAVERSE.

         The Field Traverse routine will be the data entry method of choice
         when you have a substantial amount of data  to  enter,  when  that
         data  may  be entered as a series of consecutive points,  and when
         your situation will allow you to number each point  consecutively.
         It  differs from the Traverse routine in that the Traverse routine
         will allow you to enter your choice of a  point  number  for  each
         point, and in that the Traverse routine allows neither closure and
         adjustment  of  a  traverse  nor correction of data which has been
         mis-entered.

         Access the Field Traverse routine by pressing <ALT><F1>  from  the
         Main  Menu.  The  system  prompts you to enter the number that you
         wish to assign to the initial point (the first occupied point)  of
         the  traverse.  Please respond by typing 1 then pressing <ENTER>.
         Note that numbers outside of the allowable range of point  numbers
         (1 to 1000 for stock versions) will not be accepted.


         (SurveySoft has automatically set the cursor / numeric keypad  for
         numeric entry.  While you may reset it for cursor control any time
         that you like,  SurveySoft will not respond to the characters that
         the cursor keys will generate,  and will reset the keypad  at  its
         earliest opportunity.)


         The  system  now prompts you to enter the northing coordinate that
         you wish to assign to point number 1.  Assign it a northing of 1
         + 00 by typing 100 and pressing <ENTER>.  When you are prompted to
         enter the easting coordinate for point  number  1,  assign  it  an
         easting of 1 + 00 in a similar way.


         (If  you  do  not  assign a northing at this time,  but proceed by
         pressing <ENTER>,  the system will assign by default any  northing
         which  had  previously  been  assigned  to  point number 1;  if no
         northing was previously  assigned  to  that  point,  its  northing
         coordinate is 0 + 00.)


         You  are now prompted press a key on the numeric pad.  The display
         in the bottom window shows you which numeric keys (NOT the  number
         keys  in  the  top  row  of the typewriter keyboard) correspond to
         which quadrants and field angles.  Keys 2, 4, 6, and 8 are used to
         generate field angles from the last entered traverse leg; since we
         have no previous leg, they are of course meaningless now.  Keys 1,
         3, 7, and 9 are used to enter azimuths and bearings. Key 0 is used
         to  recall the bearing between two previously entered points;  its
         use is further documented on pages 15 - 16 of this manual.  Key  5
         is not implemented at all.


         (Enter  bearings  of due north and south by entering bearings of 0
         in either adjacent quadrant.  Similarly,  enter  bearings  of  due
         east  and  west  by  entering  bearings  of  90 in either adjacent
         quadrant.  Enter a north azimuth by entering the  azimuth  in  the
         northeast  quadrant  and  a  south  azimuth  by entering it in the
         southwest quadrant.)

         If the bearing of the first leg of your traverse is known,  it  is
         of course entered at this time; otherwise, an arbitrary bearing is
         entered  which  may  later  be  rotated to conform to any required
         bearing.  For now, press number 9 on the numeric keypad to set the
         bearing  of  the  first  leg  of  your  traverse  in the northeast
         quadrant.

         The  system  prompts  you to enter the bearing of the first leg of
         your traverse.  Bearings are entered using  the  format  DDD.MMSS.
         Assign  a  bearing of N 45 45'45" E by typing 45.4545 and pressing
         <ENTER>.

         You are now prompted to enter the length  of  your  traverse  leg.
         Input  a  distance  of 100.00 feet and press <ENTER>.  If you have
         set Zenith Input to "ON" -- this tutorial  will  assume  that  you
         have  not  --  you will now be prompted to enter the zenith angle
         turned to the new point.  This angle is entered in the same way as
         is a horizontal angle,  in response to the prompt.  A zenith angle
         of  90  may be entered by simply pressing <ENTER> with no numeric
         input.


         (The zenith angle is the angle turned from the vertical to the new
         point.  Thus points at a higher elevation than the instrument will
         have turned zenith angles between 0 and 90 or between 270 and 360,
         while points below the instrument will have zenith angles  between
         90 and 270.)


         SurveySoft computes and displays the coordinates of the new  point
         and  assigns  it  the next consecutive point number (in this case,
         2), then asks that you press a key on the numeric pad for the next
         leg of your traverse.  Enter a field angle right of 90 degrees by
         pressing 6  on  the  numeric  pad,typing  90  when  prompted,  and
         pressing  <ENTER>.  When  asked  to enter the distance to the next
         point, please enter a distance of 99.5 feet.

         Now close into the initial point of your traverse  by  entering  a
         deflection  angle  to the left of 135 00'15".  Press numeric key 2
         for deflection  left,  type  135.0015,  and  press  <ENTER>.  When
         prompted, <ENTER> a distance of 100.15 feet.

         SurveySoft computes and displays the coordinates of traverse point
         number  4.  If  all  has  gone well,  point number 4 should have a
         northing of 140.91 feet and an easting of  100.91  feet.  You  may
         note  that  a 40÷foot closure is not particularly close work for a
         traverse of this size;  in fact,  it seems that  we  have  made  a
         typographical  error  in  entering  the  last leg of our traverse.
         Instead of a closing distance  of  100.15  feet,  we  should  have
         entered  a  distance  of 140.15 feet.  We are about to remedy this
         situation.

         Press <ESC> to leave the data entry portion of the Field  Traverse
         routine.  You  are  prompted  to  press the space bar to close and
         adjust the traverse, or to correct a leg.  (You may also return to
         the Main Menu by pressing <ESC> again at this point.) Please press
         the <SPACE BAR> to go to the Close and Adjust Menu.

                                  CLOSE AND ADJUST

         Before proceeding to the Close and Adjust menu,  you are presented
         with tentative northing and  easting  coordinates  for  the  point
         closed  upon.  These  are  simply  the  coordinates of the initial
         point of the traverse.  If you are closing upon the initial point,
         as we are here, press Y.  Otherwise,  if you are closing upon some
         other point of known coordinates,  press "N";  you will be offered
         the opportunity to enter those known coordinates.

         SEARCH FOR ERROR. Let us first verify the location of the error by
         pressing function key <F1>,  Search for Error.  The data that  you
         have  entered  is  highlighted  and displayed in the center of the
         screen. Verify that the data  entry  error  did  occur  at  point
         number  3  and  that  the other data were entered correctly,  then
         press function key <F2>, Correct Error.


         (If you have entered more data than can be displayed in this area,
         only the first portion will be displayed;  scroll through the data
         by pressing the <ENTER> key.  When you have  reached  the  end  of
         your  input data,  the display will scroll back to the first point
         if you continue.)


         CORRECT ERROR. We have now located the input  error  and  verified
         that  it  did  occurr at point number 3.  When you are prompted to
         enter the point at which the error  occurred,  type  3  and  press
         <ENTER>.  You  will  be  prompted  to  press a quadrant key on the
         numeric pad.  Since the correct angle is still a deflection  left,
         press  2.  You  will  be prompted to enter the new bearing.  Since
         the bearing also  remains  unchanged,  type  135.00015  and  press
         <ENTER>.  Finally, you are prompted to enter the correct distance.
         Type 140.15 and press <ENTER>.  The traverse is  recalculated  and
         the  results  displayed  in  the highlighted area of your display,
         which should now resemble Figure C.  You will return to the Search
         for Error mode.

         Note that the closing coordinates for point number 4 are now  1  +
         00.91 North and 1 + 00.38 East.  We will consider these figures to
         be within reasonable limits of accuracy for this survey.

         BALANCE  ANGLES.  Now  note  the  line above the highlighted area.
         Since you did not  enter  a  closing  angle  at  point  number  4,
         SurveySoft  has calculated the angular error based upon a computed
         line  from  the  last  occupied  point  to   the   ideal   closing
         coordinates,  and  reminded  you  that  a  closing  angle  was not
         entered.  If you like,  you may return to Correct Error  mode  and
         enter  a  closing  angle  at this time;  the angular error will be
         recalculated.  Either with or without a  closing  angle,  you  may
         select Balance angles to have the angular error balanced among all
         field  angles  --  not  angles  entered as azimuths or bearings --
         before  proceeding.   Corrected  figures  will   appear   in   the
         highlighted area.

         However,  since  your  instrument  operator has been very good (or
         very lucky),  and since your party chief has neglected the closing
         angle  (Have  you  considered  rotating your personnel?),  we will
         proceed to adjust the traverse without balancing angles.

         ADJUST TRAVERSE. Since the angular closure of this traverse is  so
         good,  you should probably consider using Transit Rule adjustment,
         which assumes that angles have been measured more accurately  than
         distances.  In  most cases,  however,  Compass Rule (which assumes
         that  angles  and  distances  were  measured  with  roughly  equal
         asccuracy) will be the method of choice.  Since the procedures for
         both  methods  are identical -- and quite simple -- let us proceed
         with a Compass Rule adjustment  by  pressing  function  key  <F4>.
         Because  adjustment  of  the traverse must be the last step in the
         Close and Adjust procedure,  you are notified when the  adjustment
         is  complete  and  are  instructed to press <ESC> to return to the
         main menu; you have no further access to the Close and Adjust menu
         at this time.

                                      INVERSE.

         To see what changes the adjustment has made  in  our  field  data,
         press function key <F3>,  Inverse.  When SurveySoft prompts you to
         enter the first point number,  please type 1  and  press  <ENTER>.
         When you are prompted to enter the next point number, enter number
         2.  Note  that  the  bearing  of  the  first traverse leg has been
         adjusted to N 45 49'44" E and that the length of the  leg  is  now
         99.73  feet.  Enter  point  number 3 and note that the field angle
         right of 90 which we entered at point  number  2  has  become  an
         angle  right of 89 46'50".  Enter point number 4 and note that the
         northing and easting of this point have now been adjusted to match
         the northing and easting of the initial traverse point.

         Your  display  should  now  resemble  Figure  D.   When  you  have
         satisfied  yourself  of  this,  press  <ESC>  to  exit the Inverse
         procedure.  SurveySoft will compute and display the acreage that
         you have inversed,  then prompt you to press <ESC> again to return
         to the main menu.  Please do so when you are ready to proceed.


         (Of course,  points need not be entered in consecutive order,  but
         our  example does happen to work out that way.  In fact,  whenever
         SurveySoft prompts you to enter a point number, you may default to
         the point immediately following  the  current  point  by  pressing
         <ENTER>.  However,  this  default must be used with caution;  if a
         value has already been assigned to that default point,  it will be
         lost.)


         (Computed  acreage  to  the nearest hundredth should be sufficient
         for most purposes;  if not,  note that area is also  displayed  in
         square  feet,  and  can  therefore  be  computed  to  any  desired
         accuracy.)

                                 ROTATE COORDINATES.

         We have entered a traverse from field data, corrected a data entry
         error,  adjusted the corrected  traverse,  inversed  the  adjusted
         traverse  and  displayed  the enclosed area.  We now would like to
         rotate the traverse so that its west line conforms to a known  due
         north÷south  bearing.  We  will  do  so  by  selecting  the Rotate
         Coordinates routine from the Main Menu.  Please do so by  pressing
         function key <CTRL><F4>.

         SurveySoft prompts you to enter a point number for the hinge point
         -- that is,  the point about which all the others will be rotated.
         This point may be any point lying upon the line whose  bearing  we
         wish  to  define  (in  this case,  the west line of our traverse).
         Please enter point number 1 in response to the prompt.

         The system now asks that you enter the known bearing away from the
         hinge point, beginning with pressing a quadrant key on the numeric
         pad.  To assign a bearing of due north to the west line, press key
         9,  NE (or key 7,  NW,  if you prefer),  then input an angle of  0
         degrees.

         You  are now prompted to enter a base point number.  This point is
         another point on the line through the hinge point whose bearing we
         wish to define.  When the  Rotation  procedure  is  finished,  the
         bearing from the hinge point to the base point will be the bearing
         that  was entered in the preceeding step.  In this case,  the only
         suitable point is point number 3.  Please enter 3 in  response  to
         the prompt.

         At this time,  SurveySoft offers you the opportunity to change the
         northing and easting coordinates  of  the  hinge  point  (and,  of
         course,  to  similarly  shift  the coordinates of the other points
         that you choose to rotate).  To facilitate  plotting  the  survey,
         let  us assign to the hinge point northing and easting coordinates
         of 0 + 00.  Please type 0 and press <ENTER> when you are  prompted
         for these coordinates.

         The  system  now  prompts  you to enter a scale factor.  The scale
         factor permanently alters the coordinates of all rotated points in
         memory,  and should be used only on the rare occasions when it  is
         necessary  to  scale  to  match known data.  In nearly all other
         cases,  the correct response to this prompt is 1,  and  1  is  the
         default  value  assigned if no other value is entered.  Respond to
         the prompt by pressing <ENTER> with no numeric input.


         (To make all distances between rotated points 1% longer,  enter  a
         scale  factor  of  1.01;  to make then 10% shorter,  enter a scale
         factor of .9,  and so on.  Note that the input of the scale factor
         in  the  Rotate  routine  is  different from the input in the List
         Coordinates routine on page ##.)


         You are now asked to enter the first point to be rotated.  This is
         the lowest-numbered point that you wish to have  affected  by  the
         Rotation  procedure.  In this case,  that point also happens to be
         the hinge point;  you should enter point number 1 in  response  to
         the  prompt.  When you are asked for the last point to be rotated,
         enter the highest-numbered point that you wish to  have  affected;
         in this case, that point is point number 4.

         SurveySoft  informs  you  when  the  procedure  is complete.  Your
         screen should now resemble Figure E.  Please press <ESC> when  you
         are ready to proceed.

                                  LIST COORDINATES.

         At  this  point  it will be helpful to prepare a sketch of what we
         have accomplished.  One convenient way to prepare  a  sketch  from
         data  in  system  memory  is to List the coordinates of the points
         that you wish  to  plot.  Access  the  List  routine  by  pressing
         function key <F4> from the Main Menu.

         SurveySoft  prompts you to enter a scale factor.  Unlike the scale
         factor  in  the  Rotate  routine,   this  scale  factor  does  not
         permanently alter coordinates in memory but only displayed values.
         (For  example,  this  enables  you to plot data at a scale of 1" =
         400' by entering a value of 400 in response to this  prompt,  then
         plotting  the  displayed  values  directly  in  inches,  while the
         coordinates assigned to all points  remain  unchanged.)  For  now,
         however, please respond to this prompt by entering 1.

         The  system  prompts  you  to  enter  the first point number to be
         listed.  Again, this is the lowest-numbered point that you wish to
         display;  please enter 1 in response to the prompt.  When you  are
         asked  for  the  last  point  to  be  listed,  input  the highest-
         numbered point that you wish  to  display;  please  enter  4  in
         response to the prompt.


         (Don't be concerned if you need to display more points  than  will
         fit  on  the  screen  at  one time.  Go ahead and enter your point
         numbers as  usual,  and  SurveySoft  will  display  the  data  one
         screenful at a time.)


         If you wish,  you may now make a simple sketch using the displayed
         data.  The results should resemble Figure F.

                                    DATA STORAGE.

         At this point,  you may be ready for a bit of a break before  con-
         tinuing.  Let  us  save the data that we have developed up to this
         point on disk,  so that it will be available when you return.  (In
         practice,  you will want to save your data frequently,  perhaps as
         often as every 10-15 minutes  when  you  are  engaged  in  complex
         calculations,  and  to make back-up copies of your data at the end
         of every session.)

         If you have not already done  so,  return  to  the  Main  Menu  by
         pressing  <ESC>.   Then  select  the  Data  Storage  routine  by
         pressing function key <F9>.


         (It  is  not really necessary in Version 3.0 to return to the Main
         Menu before making your selection.  At almost  any  time  you  may
         move   directly   to   another  menu  selection  by  pressing  the
         appropriate function key.  As you become more  familiar  with  the
         system,  you  will  find  that this approach will greatly increase
         your computing efficiency.)


         The system asks you to input the name under which  you  intend  to
         store your data.  If you have already used data file names in this
         session,  you  are offered the most recent as a default selection,
         and need only press <Enter> to select it.  This time, however,  we
         need to enter an original name.

         A  filename  may be any combination of letters,  numbers,  and the
         underscore  ("_")  symbol,  up  to  eight  characters  in  length.
         SurveySoft will not permit you to use illegal symbols or to exceed
         the  legal  length.  An extension of ".DAT" is added to the end of
         all data files to prevent accidental overwrites  and  to  simplify
         block  file  handling.  (DOS  2.0+  pathnames  are  not  currently
         supported.)

         It is generally wise to select a name  for  your  file  that  will
         recall to your mind the type of data contained in that file; thus,
         while  JonesSub  would be an excellent file name,  choices such as
         Data1, Data2,  and so on are probably not so appropriate.  In this
         case,  let us save the data that we have compiled up to this point
         as "Example".  Do so by typing Example and pressing <ENTER>.  Note
         that no quotes are necessary around SurveySoft file names.

         Your selected data drive operates briefly as  points  one  through
         four  are  stored on your data disk;  you are then informed that
         the data storage procedure is complete.  Your system  may  now  be
         safely turned off, or you may experiment with the commands that we
         have covered up to this point.


         (SurveySoft stores data in a  text  file  in  the  form  of  ASCII
         characters.  This means that SurveySoft data files may be accessed
         through  the  DOS TYPE and PRINT commands,  as well as edited with
         the EDLIN editor and many word processors.  Only  non-zero  points
         are  stored,  together  with  the  point  numbers  that  have been
         assigned to them.  In all but the very largest  data  files,  this
         approach improves disk access time and conserves disk space.)


                                   DATA RETRIEVAL.

         Make  sure  that  your operating system and SurveySoft are in your
         system's default drive and that EXAMPLE.DAT is in the  drive  that
         you have chosen as your data drive.  If your system is on, restart
         it  by pressing <DEL> while holding down both the <CTRL> and <ALT>
         keys.  If it is off,  turn it on.  Enter the date and time and  do
         any other necessary housekeeping;  then type SURVEY in response to
         the DOS prompt and press <ENTER>.  This will bring up the  Options
         Menu.  Make  your selections here -- remember that you do not have
         to re-enter the data drive unless you would like to change  it  --
         and press <ENTER> when you are ready.

         We  will  now  load  the  data  from  EXAMPLE.DAT from the disk by
         pressing function key <ALT><F9>, Load data.  If there are any non-
         zero points in active memory,  you are warned that  unless  saved,
         they  will  be overwritten,  and you are offered an opportunity to
         back up and save them.  Since we have just started  with  a  clean
         slate,  this warning is bypassed and you are prompted to enter the
         name of the file to be loaded.

         Respond by typing the  name  of  a  file  that  you  know  is  not
         currently  in the data file,  perhaps TEST,  and pressing <ENTER>.
         The system informs you that is  unable  to  find  this  file,  and
         offers  you  the  option  of  pressing  <ENTER> to retry -- either
         another disk or another filename -- or of pressing <ESC>  to  back
         up  to  the  Main  Menu.  Please press <ENTER>.  Note that you are
         offered TEST.DAT as a default selection;  to search for that  file
         on  another  disk,  you  need only insert the new disk in the data
         drive and press <ENTER>.  For now,  please type EXAMPLE and  press
         <ENTER>.  With  luck,  you  will meet with more success this time,
         and will be returned to the main menu.

                                     SIDESHOTS.

         Refer to the sketch of our  three-point  traverse  that  you  made
         earlier, or to Figure F.  Let us assume that traverse point number
         2  was  a  temporary  point  that  you  established  to locate two
         additional points that lie roughly north and south of it, and that
         you have located these two points while occupying point number  2,
         turning  angles  and measuring distances to them while using point
         number 1 as a backsight.  Access the Sideshot routine by  pressing
         function key <F2>, Sideshot.

         When  the  system prompts you for a backsight point number,  input
         number 1. When you are prompted for the number of  the  occupied
         point,  enter 2.  Input an angle right of 132 15'15" by pressing 6
         on the numeric keypad,  typing  132.1515,  and  pressing  <ENTER>.
         When prompted, input a distance of 75.12 feet; if necessary, input
         a  zenith  angle  of  90.  Note  that,  unlike the Field Traverse
         routine,  you are now prompted to enter the  point  number  to  be
         assigned to the new point.  Since the current point number is 2,
         if  you respond to this prompt by pressing <ENTER> without numeric
         input, the new coordinates will be assigned to point number 3.  In
         this case,  the current  coordinates  of  point  number  3,  which
         remains useful to us, will be overwritten and lost.


         (If  you  will  be entering bearings rather than field angles,  it
         makes no difference what point you enter  here.  If  you  are  not
         comfortable  entering  a random point number,  you may bypass this
         selection entirely by pressing <ENTER> with no numeric input.)

         (For our purposes here, the current point number is defined as the
         last point number that was entered by the user.)


         Obviously,  then,  we must assign some new point number, say 5, to
         this point.  Do So by typing 5 and pressing <ENTER>.

         In the Sideshot routine,  as opposed to  the  Traverse  and  Field
         Traverse  routines,  SurveySoft  assumes  that subsequent data are
         input using the same backsight  and  occupied  point.  Locate  the
         second  new  point  at a field angle right of 270 17'17" (measured
         from point  number  1)  by  pressing  6  on  the  numeric  keypad,
         typing 270.1717,  and pressing <ENTER>.  Input the  distance  from
         point  number  2  by typing 68.13 and pressing <ENTER>.  Since the
         current point number is now 5, and since point number 6 is unused,
         we may assign the default value  of  6  as  the  point  number  by
         pressing <ENTER> with no numeric input.

         If you had other points that were located from the same setup, you
         would enter them at this time.  If you had other points  to  enter
         using  the Sideshot routine which were located using other setups,
         you would do so either by returning to the Main Menu and selecting
         Sideshot again or by pressing function key <F2> while still in the
         Sideshot routine.  In either of these cases, you would be prompted
         to enter a new backsight number,  and would proceed with  the  new
         setup data as above.

         You may wish to update the sketch of our data that you made previ-
         ously,  or refer to Figure G.  List the coordinates of points 1 to
         6, and plot those which have not yet been plotted, bearing in mind
         that the coordinates of point number 1 are 0 + 00 North,  0  +  00
         East.  Inverse the lines 1 - 6,  6 - 5,  5 - 3,  and 3 - 1.  Label
         the lines that you have Inversed with their bearings and  lengths.
         When  you  have  finished,  your  sketch should resemble Figure G.
         When you are satisfied, please return to the Main Menu.

                                  ENTER COORDINATES


         Now let us assume that line 1 - 3 is not in fact the west line  of
         the parcel that we are surveying,  but is rather the centerline of
         a road which has an 80-foot right-of-way.  To establish the right-
         of-way line which is the actual boundary of our  survey,  it  will
         first be necessary to establish a point which is 40.0 feet east of
         line  1 - 3.  Certainly one option is to enter this point by means
         of the Sideshot routine;  however,  this also provides us with the
         opportunity  to  introduce  the Enter Coordinates routine.  Please
         enter this routine by pressing <ALT><F4>.

         SurveySoft now prompts you to enter the point to which you wish to
         assign new coordinates.  Please type number 7 and  press  <ENTER>.
         You  are prompted to enter the northing that you wish to assign to
         this  point.  Let us arbitrarily assign a northing coordinate of 0
         + 00 by typing 0 and pressing <ENTER>.  When you are  prompted  to
         enter  an  easting  for this point,  please enter 40.  We have now
         established point number 7 due east of point  number  1  and  40.0
         feet east of the center of the road.

         The  system prompts you to enter another point number to which you
         would like to assign  coordinates.  You  may  enter  a  new  point
         number  at  this  time;  or as always,  the next consecutive point
         number may be assigned by default by simply pressing  <ENTER>.  To
         exit from this routine, simply press <ESC>.

                           BEARING / BEARING INTERSECTION

         Let us now compute the intersection of the north line of our tract
         with  the east right-of-way line of the road centering on line 1 -
         3.  We have already established point number 7 on that east right-
         of-way  line.  Now  select  the  Bearing  /  Bearing  Intersection
         routine by pressing <F5>.

         SurveySoft  prompts you to enter the first point number.  This may
         be either point through which a line of known  bearing  is  to  be
         run;  in this case, please enter point number 7.  Since the right-
         of-way of the road is to center upon the west line of  out  tract,
         it  must  have  a  bearing  of  N  0 00' E.  Enter this bearing by
         pressing 9 on the numeric keypad,  then entering an  angle  of  0.
         (Note  that  it is important that the bearing entered be a bearing
         toward the intersection point.  In this case, entering an angle of
         S 0 W might yield an incorrect result.)

         The system prompts you to enter the number  of  the  second  point
         through  which a line of known bearing is to be run.  Please enter
         point number 3.

         At this point the usual course would be to enter  the  bearing  of
         the  north  line  of  our  tract by referring to our sketch,  then
         inputting the proper quadrant  and  bearing.  However,  SurveySoft
         also  provides  a shortcut in the Bearing Recall function.  Please
         press 0 on the numeric keypad.

         Selecting '0' as the quadrant key  informs  the  system  that  the
         number about to be input is not,  in fact,  a bearing, but instead
         specifies two point numbers,  and that the bearing  between  these
         two  points  is  to  be  computed  and  entered  into  the ongoing
         calculation.

         The  format  for  entering the point numbers is #.00##.  Any legal
         point number may be typed to the  left  of  the  decimal.  To  the
         right  of the decimal,  any legal point number may be entered with
         leading zeroes to make a total of four decimal  places.  Thus,  to
         recall  the  bearing  from  point 1 to point 4,  enter 1.0004;  to
         recall the bearing from point 1 to  400,  enter  1.0400.  At  this
         time,  to recall the bearing from point 3 to point 5,  type 3.0005
         and press <ENTER>.

         SurveySoft  computes  the  coordinates  of the intersection of the
         north property line and the right-of-way line, then prompts you to
         input a new point number for the intersection point.  Please enter
         point number 8.

         Now return to the Main Menu.  Inverse from point 7 to point  8  to
         verify  that  the  bearing of the right-of-way line is due north -
         south.  Check the coordinates of point number 8 to verify that  it
         is at 0 + 40 East.  Inverse from point 8 to point 5 to verify that
         the bearing of the new north line is as it should be,  then from 5
         to 3 to verify that the interior angle 8-5-3 is in fact 0 degrees.
         Return to the Main Menu and save your file as EXAMPLE.  Note  that
         since  the  file  EXAMPLE  already  resides on this disk,  you are
         notified that it  is  about  to  be  overwritten  and  offered  an
         opportunity  to  back up and try again with another file name.  In
         this case, since you do wish to update the existing file,  respond
         by pressing <ENTER>.
                          BEARING / DISTANCE INTERSECTION

         Now let us assume that the road that runs along the west  line  of
         our  tract terminates in a cul-de-sac 120.0 feet in diameter,  and
         that the cul-de-sac is centered upon point number  1.  Our  sketch
         will now look something like Figure H.

         First we will establish the point at which the 80-foot road right-
         of-way intersects the radius of the cul-de-sac.  This is the point
         labeled in Figure H as point number 9.  Please return to the  Main
         Menu if you have not already done so,  then press <F6>,  Bearing /
         Distance Intersection.

         SurveySoft prompts you to enter the point through which  the  line
         of known bearing runs.  Please enter point number 8 in response to
         this prompt.

         The  system then prompts you for a bearing from the point that was
         just entered.  Input a due south bearing  by  pressing  1  on  the
         numeric  pad,  then  entering an angle of 0 degrees in response to
         the next prompt.

         You are now prompted to enter the number of the point  from  which
         the  distance  to the intersection point is known.  Enter number 1
         in response to the prompt;  when the system requests the  distance
         to the intersection point, enter a distance of 60 feet, the radius
         of the cul-de-sac.

         SurveySoft  displays  the  distance from the first point number to
         the first of two solutions to the intersection.  In this  case,  a
         distance  of  98.80  feet is about the distance that we would have
         anticipated from point number 8 to point number 9, so enter 9 when
         the system requests a point number to  assign  to  this  solution.
         The  system  now  displays the distance from point 8 to the second
         possible solution.  It is apparent that 188.25 is the distance  to
         the  point  at  which  the  easterly  road right-of-way line would
         intersect the south edge of the  cul-de-sac.  Since  there  is  no
         immediate reason for us to assign a point number to this solution,
         press <ENTER> without inputting a number.

         (Note  that had these solutions been displayed in reverse order --
         had the solution we needed been the second one  to  appear  --  we
         would  have  pressed  <ENTER> with no numeric input in response to
         the first prompt.  Note also that  here  and  in  the  Distance  /
         Distance Intersection routines,  SurveySoft's automatic assignment
         of consecutive point numbers is disabled.



                          DISTANCE / DISTANCE INTERSECTION


         Now we will establish the other point at the throut of the cul-de-
         sac,  the point labeled number 10 on the sketch.  You have already
         become  familiar  with  several  means  of   accomplishing   this,
         including  another  Bearing  / Distance Intersection or a Sideshot
         (occupying point number 9 and turning 90 degrees left  from  point
         number  8  for a distance of 80 feet).  However,  we will now make
         use of the Distance / Distance  Intersection  routine.  To  access
         this routine, please press function key <F7>.

         We  know  that  point number 10 is 80 feet west of point number 9,
         because that is the width of the right-of-way.  We know that it is
         60 feet northwest of point number 1, because that is the radius of
         the cul-de-sac.  In response to SurveySoft's request for  a  point
         number,  either 1 or 9 might be input.  In this case,  enter point
         number 9 in response to the request for the first point number and
         enter a distance of 80 feet.

         Respond to the request for a second  point  number  by  enter  our
         other  possible  selection,  point number 1,  and a distance of 60
         feet.  SurveySoft displays the coordinates of the  first  possible
         solution to the intersection problem,  then prompts you to input a
         point number.  Since we know that the solution that we are looking
         for is northwest of  point  number  1,  and  since  the  displayed
         coordinates are south and east of that point,  respond by pressing
         <ENTER> without inputting a point number.

         (Note  that in this situation,  and the corresponding situation in
         the Bearing / Distance Routine,  SurveySoft's automatic assignment
         of  the next consecutive point number is overridden.  Make sure to
         assign a number to the solutions that you wish to retain in  these
         situations.)

         The system now displays the coordinates  of  the  second  possible
         solution.  Since this solution looks reasonable,  assign number 10
         in response to the prompt.

                            INVERSE WITH CURVES AND AREAS

         Review the sketch of our tract and note that  all  points  on  its
         perimeter have been established except point number 11, the inter-
         section  of  the south line of the tract with the east line of the
         cul-de-sac.  Please establish point number  11  at  this  time  by
         pressing  function key <F2>,  Sideshot.  Backsight point number 6,
         occupy point number 1,  and use numeric key 6 to  input  an  angle
         right  of  0  degrees.  Enter a distance of 60 feet and assign new
         point number 11.  When you have finished, press function key <F3>,
         Inverse.

         Enter point number 9 in response to the system's request  for  the
         initial  point  number.  Respond to subsequent prompts by entering
         point numbers 8, 5, 6, and 11 in turn.

         We have now arrived at the first point on the radius of  the  cul-
         de-sac.  The  next point number to be input is the radius point of
         the curve. Press <ALT><C> to enter the curve; when prompted, enter
         1, the number of the radius point.  Finally,  enter 9,  the number
         for  the  end  point  of  the  curve,  when  prompted  to  do  so.
         SurveySoft computes and displays curve data  and  compensates  for
         the curve in its area calculations.

         (Of course,  the curve need not be the last course to be inversed;
         one  or  more  curves  may  occur at any point in the figure being
         inversed.)

         Update your sketch if you wish,  showing right-of-way  information
         and  the  new  lengths  of the north and south lines of the tract.
         When you have finished, it should resemble Figure I.

         Verify that the information on your sketch is  in  agreement  with
         that shown here.  When you are satisfied,  return to the Main Menu
         and save your data as EXAMPLE.

                         FIXED AREAS (ANGLE / SIDE / ANGLE)

         We will now assume that you intend to lay off a  tract  containing
         0.5  acres,  bounded on the west by the road right-of-way,  and on
         the north and south by the easterly extension  of  the  north  and
         south  lines  of  our  tract.  This  may be easily accomplished by
         using the Fixed Areas  (A/S/A)  routine.  Access  it  by  pressing
         function key <F8>.

         SurveySoft  prompts  you  to  enter  the  first base point number.
         Enter point number 5 in response to the prompt.  The  system  will
         prompt  you to press a numeric key and enter a bearing.  Enter the
         bearing of the north line by pressing numeric 0,  Recall  Bearing,
         and  entering  3.0005.  When  the  system prompts you to enter the
         second base  point  number,  input  point  number  6.  Recall  the
         bearing  of  the  south  line  by  pressing numeric 0 and entering
         1.0006.

         The system prompts you to enter the bearing (in  square  feet)  of
         the  tract  that  you  wish to lay out.  We know that the boundary
         which we have previously inversed contains 6166 square  feet.  One
         half  acre contains 21780 square feet,  so the difference of 15164
         square feet is the additional area we need to arrive at a total of
         0.5 acres.  Enter 15164 in response to the prompt.

         You are prompted to press a numeric key to set the bearing of  the
         new  side.  For  the sake of neatness,  set the bearing of the new
         side to South 0 degrees East by pressing numeric 3 and entering  a
         bearing of 0 in response to the prompt.

         When you are requested to enter the first new point number, please
         enter  12.  This  is  the point which lies on the same line as the
         first base point.  When you are requested to enter the second  new
         point number you may enter 13 or let the system assign the default
         value of 13 by pressing <ENTER> with no numeric input.

         SurveySoft  computes and displays the coordinates of points 12 and
         13.  If you like,  you may now update your working  sketch,  which
         should now resemble Figure J.

                          FIXED AREA (SIDE / ANGLE / SIDE)

         Your  client  has now informed you that instead of 0.5 acres,  the
         tract  should  in fact have contained 0.6 acres.  He wishes to add
         the additional acreage to the north side of the tract,  but  would
         like  the  amount of road frontage on the west to remain constant,
         as well as the bearing of the east line.  To no  one's  particular
         surprise, it is time to press <ALT><F8>, Fixed Area (S/A/S).

         The  system  prompts  you to enter the base point number.  This is
         the number of the point which is to be adjusted  in  arrriving  at
         the  new  area,  corresponding  to  point  number  12 in Figure K.
         Please enter 12 in response to the prompt.  You are  now  prompted
         to  press  a  key on the numeric pad.  This key -- and the bearing
         which follows it -- will determine the bearing of the  line  along
         which  point  number  12 is to be adjusted.  Let us retain the due
         north bearing of the east line by pressing numeric 9 and  entering
         a bearing of 0.

         Wneh  you are prompted to enter the hinge point number,  enter the
         number of the point which is to remain fixed -- upon which the new
         line will hinge.  Please enter point 8 at this time.

         You  are  asked to enter an area in square feet.  Since we wish to
         add one tenth of an acre or 4356 square feet, please enter 4356 in
         response to the prompt.  SurveySoft calculates the coordinates  of
         the  new  northeast  property  corner and prompts you to enter the
         point number to be assigned to the new point.  Please enter number
         14;  the coordinates of point  number  14  are  displayed  on  the
         screen.

                                TRAVERSE WITH CURVES

         If you like,  you may update your screen at this time;  it  should
         resemble Figure K.

         It  is now time to verify that the information shown on our sketch
         is correct as shown.  Please save your data,  then return  to  the
         Main  Menu.  Press  F1  to  select  the Traverse routine.  We will
         begin entering data with the  point  presently  labeled  as  point
         number 1;  however,  we will assign it a new point number to avoid
         overwriting our current data.  Enter an ititial  point  number  of
         100  and any convenient starting coordinates.  (Good choices might
         be (0,0) or the current coordinates of point number 9.)

         From this initial point, enter traverse data as follows:

                N  0 degrees 00'00" E          98.80 feet
                N 70 degrees 23'25" E         186.80 feet
                S  0 degrees 00'00" E         165.95 feet
                S 79 degrees 26'19" W         159.69 feet

         This brings us to point number 11 ( now point number  104  ),  the
         intersection  of  the  south line of the survey with the radius of
         the cul de sac.  Press <ALT><C> to enter the radius point  of  the
         curve  that  we  will  be traversing.  You are prompted to enter a
         bearing for the initial tangent of the curve.  In  this  case,  we
         know that the south line of our survey is radial to the curve,  so
         we may enter the bearing of the tangent as a deflection  right  of
         90  degrees  from  our  current  bearing.  Press  8 on the numeric
         keypad to enter a deflection right, then enter 90 degrees.

         The  system  asks  if  the curve to be traversed is a curve to the
         left or to the right.  In this case,  the curve is concave to  the
         left,  so enter L (or l).  SurveySoft requires at least two values
         to compute the curve,  one of which must be either the  radius  or
         the  central  (  deflection ) angle.  You will be prompted in turn
         for the radius, delta,  tangent,  and arc of the curve,  until two
         values  have  been entered or it has been determined that the data
         entered is not sufficient.  In our example,  the radius is  known,
         so respond to the prompt for a radius by entering 60.

         You  will  be  prompted  for  the  delta and then for the tangent,
         neither one of which may be very conveniently determined from  our
         sketch.  Respond  to  each  of  these prompts by pressing <ENTER>.
         Then,  when you are prompted for the arc,  enter 39.40  from  your
         sketch or from figure K.  The curve is computed and displayed, and
         you  are  prompted  to  enter a point number for the radius point,
         then  the  point  of  tangency.  These points may be entered indi-
         vidually or by using the system default  values,  which  will,  as
         usual,  assign the next consecutive point number after the current
         ( point of curvature ) number.

         Note that it is not necessary for the curve to be the last  course
         traversed;  our  example  just happens to work out that way.  Note
         also that compound and reverse curves may be entered  by  pressing
         <ALT><C>  again  at this point.  Exit from the Traverse routine by
         pressing <ESC>.  The traversed area  is  computed  and  displayed,
         with the curve accounted for.  Return to the Main Menu by pressing
         <ESC> again.

                                RADIAL INVERSE

         Finally,  having arrived at the correct dimensions for our  sample
         tract,  it  is  time  to  consider the actual field staking of the
         tract.  This could be accomplished by using the  Inverse  routine,
         and  there may be cases in which it is easiest to do so;  however,
         SurveySoft also provides  you  with  a  Radial  Stakeout  routine.
         Radial  Stakeout  bears the same relation to Inverse that Sideshot
         bears to Traverse;  that  is,  it  will  retain  a  backsight  and
         occupied point rather than moving from point to point as you enter
         data.  Please access this routine by pressing <ALT><F3>.

         Assume  that  you wish to establish all of the perimeter points of
         the tract while occupying point number 2  and  sighting  on  point
         number  1.  In  response  to  the  system prompts,  enter 1 as the
         backsight point number and 2 as the occupied point number.

         In response to the prompt for the next point number,  please enter
         point numbers 9,  8,  4,  13, and 11 in turn.  Your display should
         now resemble figure L.

         When you are ready, press <ESC> to return to the Main Menu, and
         again to reutrn to the Options Menu.  Press it once more, and you
         will be warned that you are leaving the SurveySoft program.  One
         more time, and you are returned to DOS.


                                     CONCLUSION


         Although this concludes the instruction manual for the  Coordinate
         Geometry section of SurveySoft,  please realize that,  as with any
         other tool,  as you grow in profficiency,  you will discover  uses
         that  you  (  and  perhaps  the  author  )  are  not yet aware of.
         Experiment.  Make a few errors to see how the system  will  handle
         them.  If  you  are unsure as to how a particular procedure may be
         used to accomplish a given task,  by all means,  try it -- then be
         sure to verify your results by some other means.

         Remember  that  SurveySoft  is  distributed  on a shareware basis.
         This means that  it  exists  only  through  your  good  faith  and
         honesty.  If you are satisfied that SurveySoft will make a contri-
         bution  to your operation,  please be sure to mail the recommended
