DemoCoGo3.0
Important stuff first!:
This program is a demo of the complete program. It may be included
it in Software Libraries such as Fred Fish, but please include this
ReadMe file, the command.list and the data files so that other users may
know where to obtain a manual, the fully implemented program and any
future updates, or just the CoGo User's Newsletter.
The program is compiled from AC/FORTRAN which is owned by absoft
Software, Inc. It requires 1/2 Meg of memory and one disk drive. The
coordinate saving feature and print-out capability are disabled in this
version.
There was not room on disk to put more than a command description
with out explanation on this disk. The fully implemented version of the
program with manual is available by mail from D. R. Benson. The address
is 1402 Olive Street, Sanger, CA 93657-3439 U.S.A. For a donation of
$25.00 you will receive a copy of the manual and will be put on the
mailing list for update notices.
Since I am not independently wealthy, I can only provide the
manuals by donation. Future updates will be accelerated by donations,
enabling me to spend those resources needed to make updates. One thing
that I would like to do is be available through one of the on-line
networks for assistance in problem solving. Until then I am available
by mail at the address given above.

INTRODUCTION
CoGo is a function name of problem-oriented computer systems that
enable the user to solve geometric problems related to surveying and
civil engineering. This coordinate geometry, or CoGo, can be used to
solve problems related to highway design, surveying, subdivision layouts
and construction. CoGo may be applied to other problems, similar in
nature to those described above.
CoGo is based on a rectilinear coordinate system where points are
located as being so many feet North and East of a fixed point with the
coordinates of 0.0' N, 0.0' E. Those points may be used to define
locations of control points of rights-of-way, highway alignment, or
other points of known reference. A supplementary system for vertical
profiles is also available. Output is to the monitor, printer, or
plotter, while input is from keyboard or file.
PROGRAM DESCRIPTION
This implementation of CoGo (version 3.0) is tailored to run on
personal computers. Presently, on the Amiga, it only runs under CLI. The
fully functional version of the program allows storage of up to 9,999
points, 1995 of which are stored by a alphanumeric name, and 50 curves.
By use of approximately 80 commands, invoked in either long form or
short (mnemonic) form, solutions are generated by the computer.
Numerical significance of 16 significant places is available for
distances and seconds of angles (although the later is only practical to
1 significant decimal place.) Unknown distances, azimuths and angles my
be indicated by operators on points defining those unknowns.
Input may be from keyboard or from stored file. Corresponding
output is on monitor only on this demo version of the program. The fully
functional version of the program also outputs to printer. In the fully
implemented version points may be stored on disk upon completion of each
'job' and may be restored from disk on subsequent 'jobs.' A 'job' is a
complete set of CoGo commands and related information to solve a
definite problem. Multiple 'jobs' may be executed on one 'run'.
Points are referred to by numbers, noted without decimal point, in
the range from 1 to 7999, or by name, up to 12 alphanumeric characters,
in the range from 8000 to 9995. Curves are referred to by numbers,
divisible by 10, without decimals, in the range from 10 to 500 (i.e. 50
curves.) Angles and azimuths are measured in a clockwise direction and
are entered as degree-minute-seconds, separated by spaces.
Counterclockwise directions for angles and azimuths may be indicated
with a negative degree, except when the degree is zero.
INPUT FORMAT
Each line of input is started by a command. First on the line is the
command, either in long or short form. Next on the line is the data for
that command. Optionally, a comment can finish the line. The comment is
preceded by a slash (/) which must be separated from the data by at
least one blank.
OUTPUT
SCREEN: All output of calculations and point coordinates is displayed
on the screen for user verification and, with input from a file, user
confidence.
PRINTER: (Only on fully implemented version of the program) Optional
printer output is available at the beginning of a job or after an
END/OF/JOB command during a run. Printed results are in a similar format
to screen output. Printed output is designed for 8 1/2 inch wide paper.
Headings with date, time, program version number and point file name are
printed on each page.
PLOTTER: Plotting commands are NOT implemented in this release (3.0).
Accuracy of output is three decimal places for coordinates and distances
and one decimal place for seconds of angles.
Program Set-Up
In CLI type: cogodemo3.0 (case is not important). If you are not
in the directory cogodemo3.0 is in, include the path before the name.
(If you have problems with any of these requirements, consult the Amiga
Manual, a Amiga-User friend, a computer club or me for help.)
In the fully functional version of the program, the program will
default file storage and retrieval to the directory the program is
started from unless you include the path name with the file name when
the program asks for the file name. If you are totally unable to get the
program running, write to me describing your computer setup and what you
have tried to do.
