GAMMON IV (VT100 ANSI EDITION)
|
|
|
|
|
|

This is a patched version of "Gammon IV, Version 2.0, April 1, 1986", a
|
|
full-screen backgammon for CP/M.
|
|
|
|
I patched the game to use VT100 compatible escape sequences (including
|
|
ANSI color).
|
|
|
|
Therefore, I removed most of the "user patch area" and hardcoded the
|
|
VT100 sequences in the C code, replaced the asm code of gotoxy() with C
|
|
code and removed the Kaypro graphics routines (and the "G(raphics"
|
|
command) as it is not needed for my VT100 version.
|
|
|
|
BACKGMMN.COM is the compiled and ready-to-run game.
|
|
|
|
Have fun playing!

Compiling the game
|
|
|
|
See Compiler/Compiling.md for information on compiling the game on CP/M.
|
|
|
|
|
|
From the original Version 2.0 READ.ME:
|
|
|
|
Improvements for Version 2.0 include:
|
|
|
|
a) Several bugs and poltergeists, especially in the Arrange command,
|
|
have been completely exorcised. No bugs have been found in the Play
|
|
command for months; but, as before, Gammon IV will not invariably
|
|
recognize a forced move, either in your play or in its own. Gammon
|
|
IV knows and obeys all other official rules of backgammon.
|
|
|
|
b) There are no "hidden" commands anymore. All commands are now shown
|
|
in the command lines, including X(pert.
|
|
|
|
c) Input error handling now documents the BAR, HOME and HELP commands,
|
|
so first-time players do not need to read anything else in order to
|
|
play the game successfully. The X(pert mode dispenses with these
|
|
messages, so X(pert actually does mean expert, now!
|
|
|
|
d) The "break" command is Control-C again, instead of ESCAPE. It was
|
|
all too easy to hit ESC instead of 1 on the Kaypro keyboard, leading
|
|
to an inadvertently paused game.
|
|
|
|
e) The sanction against cheating (your opponent became Torve) has been
|
|
removed.
|
|
|
|
f) If the cube is doubled during the opening rolloff to see who goes
|
|
first, and the cube value reaches 8, additional pairs on the dice
|
|
have no further effect. The cube's opening value will not go
|
|
above 8.
|
|
|
|
The computer's three styles of play have not been changed. Judging from
|
|
the feedback I've received, Gammon IV plays acceptably well at the
|
|
current levels. All information needed to re-compile the program is
|
|
included in the BACKGMMN.C file, including the details of C/80 3.1
|
|
configuration. The compile and link steps are governed by BACKGMMN.SUB.
|
|
|
|
This program is in the public domain, so distribute it freely.
|
|
|
|
Enjoy!
