# Compiling Gammon IV
|
||||
|
||||
## Requirements
|
||||
|
||||
To compile this program, you need the following:
|
||||
|
||||
* The Software Toolworks' C/80 v3.1 compiler for CP/M
|
||||
* Microsoft MACRO-80 assembler (M80.com)
|
||||
* Microsoft LINK-80 linker (L80.COM)
|
||||
|
||||
All of these tools can also be found here:
|
||||
http://www.retroarchive.org/cpm/lang/lang.htm
|
||||
|
||||
## Configuration
|
||||
|
||||
The C compiler needs to be configured in order to be able to compile Gammon IV.
|
||||
|
||||
Just use CCONFIG.COM to make the following settings:
|
||||
|
||||
Symbol table size: 512
|
||||
String constant table: 3200
|
||||
Dump constants after each routine: YES
|
||||
Macro table size: 500
|
||||
Switch table size: 128
|
||||
Structure table size: 200
|
||||
Merge duplicate string constants: YES
|
||||
Assembler: C/80's AS
|
||||
Initialize arrays to zero: < 256 BYES ONLY
|
||||
Generate ROMable code in Macro-80: YES
|
||||
Screen size: 24 (doesn't matter)
|
||||
Generate slightly larger, faster code: NO
|
||||
Sign extension on char to int conversion: YES
|
||||
Device for library files: A: (your choice)
|
||||
|
||||
## Compilation
|
||||
|
||||
I assume that all of the following files are placed on a hard disk or "big" floppy disk.
|
||||
If you are compiling this game on a old system with limited disk space, please look into backgmmn.c, where you can find tips on how to distribute the files onto several disks.
|
||||
|
||||
The following files are needed:
|
||||
BACKGMMN.C, GAMEPLAN.C, GAMEPLAN.HDR, MYLIB2.C,
|
||||
|
||||
From the C compiler:
|
||||
PRINTF.C, STDLIB.REL, CLIBRARY.REL, C.COM
|
||||
|
||||
Assembler/Linker:
|
||||
L80.COM, M80.COM
|
||||
|
||||
To use the submit scripts, you also need ``SUBMIT.COM`` from your CP/M installation.
|
||||
|
||||
Using ``SUBMIT BGMAKE``, all steps of compiling, assembling and linking will run.
|
||||
|
||||
Using ``SUBMIT BGCLEAN``, all compiled files and intermediary files will be deleted.
|
||||
|
||||
If you don't want to use the script or just want to compile some parts, these steps are taken in the script:
|
||||
|
||||
c -m backgmmn
|
||||
m80 =backgmmn
|
||||
c -m gameplan
|
||||
m80 =gameplan

MYLIB2.C
|
||||
|
||||
These routines are CONDITIONALLY compiled; i.e., only as needed.
|
||||
|
||||
----------------------------------------------------------------------
|
||||
Incorporates special mods used by my Backgammon game, BACKGMMN.C etc.
|
||||
----------------------------------------------------------------------
|
||||
|
||||
A set of common I/O functions that seem to turn up a lot in my programs,
|
||||
including terminal functions for Kaypro 10, 4'84, 2X etc.
|
||||
|
||||
Uses Software Toolworks' C/80 3.1 compiler. Place #include "mylib2.c" at the
|
||||
end of your source file for correct CONDITIONAL COMPILATION.

|
||||
** WARNING ** These routines use direct console IO, bdos function 6!
|
||||
|
||||
YOU MUST CALL INIT_LIB() BEFORE USING THESE ROUTINES!
|
||||
|
||||
======= UTILITIES =======
|
||||
|
||||
* init_lib() - CALL THIS FIRST, OR THE RESULT WILL BE VERY STRANGE!
|
||||
*
|
||||
* puts(p) - unformatted print, e.g., puts("Hello, sailor!\n");
|
||||
* gets(p,max) - printable input only, no prompt character
|
||||
*
|
||||
* ask(p) - demand Yes or No response to question p
|
||||
* random() - effective random 16-bit integer IFF gets() is used
|
||||
* sleep(n) - sleep n/10ths of a second, roughly (from C80.LIB)
|
||||
* rollup() - roll up 23 lines of screen
|
||||
* ONscript() - printer echo ON for output via puts, chrout
|
||||
* OFFscript() - printer echo OFF for output via puts, chrout
|
||||
* ONinterrupt() - Ctl-C, Ctl-B cause program exit
|
||||
* OFFinterrupt() - Ctl-C, Ctl-B cause comedy
|
||||
* hide_input(p,max) - like gets, but used when entering passwords
|
||||
* chrout(c) - if scripting, echo output also to LST:
|
||||
* putscreen(p) - like puts, but always and only to screen
|
||||
|
||||
|
||||
======= KAYPRO 10 TERMINAL/VIDEO FUNCTIONS =======
|
||||
|
||||
* gotoxy(x,y) - 0,0 is top left, horz <= 79 precedes vert <= 24,
|
||||
* where 0,24 is on the 25th, status, line.
|
||||
* beep() - terminal bell
|
||||
* home() - home cursor, do not clear screen
|
||||
* clr_screen() - home and clear
|
||||
*
|
||||
* shadow_box(h,v,x1,y1,x2,y2) - like box, but with shadow, calls box
|
||||
* box(tlx,tly,brx,bry) - draw a line box, coords: topleft XY, bottomright XY
|
||||
* note that box calls ldraw(x1,y1,x2,y2), below
|
||||
*
|
||||
* clr_lend() - clear from cursor to end of line
|
||||
* clr_send() - clear from cursor to end of screen
|
||||
* rev_vid(),
|
||||
* nor_vid() - reverse field
|
||||
* dim_vid(),
|
||||
* bri_vid() - low/high intensity
|
||||
* on_blink(),
|
||||
* off_blink() - blinking chars
|
||||
* ul_start(),
|
||||
* ul_stop() - start/stop underline
|
||||
* save_cursor(),
|
||||
* retn_cursor() - remember/restore current cursor location
|
||||
* ins_line(),
|
||||
* del_line() - insert/delete screen text line
|
||||
* on_cursor(),
|
||||
* off_cursor() - hide/show cursor
|
||||
* vm_on(),
|
||||
* vm_off() - "Video Mode" commands
|
||||
* pixel(x,y) - draw pixel at x,y (video coords, x <= 159, y <= 99)
|
||||
* no_pixel(x,y) - erase pixel at x,y
|
||||
* ldraw(x1,y1,x2,y2) - draw/ erase graphics line, see discussion for box
|
||||
* lwipe(x1,y1,x2,y2) - range for video coordinates as for pixel

GAMNIV20.LBR
|
||||
------------
|
||||
Gammon IV, Version 2.0, April 1, 1986. Full-screen backgammon for CP/M.
|
||||
|
||||
This is the April Fool's Day (1986) edition of Gammon IV, the first major
|
||||
update in many months.
|
||||
|
||||
BACKGMMN.COM is the compiled and ready-to-run object file. It requires
|
||||
either an ADM-3A compatible terminal ("old" Kaypro) or a screen with video
|
||||
characteristics exactly like the Kaypro 2X, 4'84 or 10. However, this
|
||||
version has the same CRT Module as formerly, including a clearly-marked user
|
||||
patch area for non-Kaypro terminals.
|
||||
|
||||
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 and G(raphic. The G(raphic command
|
||||
turns on the Kaypro video-able display.
|
||||
|
||||
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!

# Gammon IV (VT100 ANSI edition)
|
||||
|
||||
By:
|
||||
David C. Oshel
|
||||

|
||||
Ames, Iowa 50010
|
||||
|
||||
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](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 set of common I/O functions that seem to turn up a lot in my programs,

including terminal functions for Kaypro 10, 4'84, 2X etc.
|

Uses Software Toolworks' C/80 3.1 compiler. Place #include "mylib2.c" at the

end of your source file for correct CONDITIONAL COMPILATION.

|

** WARNING ** These routines use direct console IO, bdos function 6!
|
||||
|
||||
YOU MUST CALL INIT_LIB() BEFORE USING THESE ROUTINES!
|
||||
|
||||
======= UTILITIES =======
|
||||
|
||||
* init_lib() - CALL THIS FIRST, OR THE RESULT WILL BE VERY STRANGE!
|
||||
*
|
||||
* puts(p) - unformatted print, e.g., puts("Hello, sailor!\n");
|
||||
* gets(p,max) - printable input only, no prompt character
|
||||
*
|
||||
* ask(p) - demand Yes or No response to question p
|
||||
* random() - effective random 16-bit integer IFF gets() is used
|
||||
* sleep(n) - sleep n/10ths of a second, roughly (from C80.LIB)
|
||||
* rollup() - roll up 23 lines of screen
|
||||
* ONscript() - printer echo ON for output via puts, chrout
|
||||
* OFFscript() - printer echo OFF for output via puts, chrout
|
||||
* ONinterrupt() - Ctl-C, Ctl-B cause program exit
|
||||
* OFFinterrupt() - Ctl-C, Ctl-B cause comedy
|
||||
* hide_input(p,max) - like gets, but used when entering passwords
|
||||
* chrout(c) - if scripting, echo output also to LST:
|
||||
* putscreen(p) - like puts, but always and only to screen
|
||||
|
||||
|
||||
======= KAYPRO 10 TERMINAL/VIDEO FUNCTIONS =======
|
||||
|
||||
* gotoxy(x,y) - 0,0 is top left, horz <= 79 precedes vert <= 24,
|
||||
* where 0,24 is on the 25th, status, line.
|
||||
* beep() - terminal bell
|
||||
* home() - home cursor, do not clear screen
|
||||
* clr_screen() - home and clear
|
||||
*
|
||||
* shadow_box(h,v,x1,y1,x2,y2) - like box, but with shadow, calls box
|
||||
* box(tlx,tly,brx,bry) - draw a line box, coords: topleft XY, bottomright XY
|
||||
* note that box calls ldraw(x1,y1,x2,y2), below
|
||||
*
|
||||
* clr_lend() - clear from cursor to end of line
|
||||
* clr_send() - clear from cursor to end of screen
|
||||
* rev_vid(),
|
||||
* nor_vid() - reverse field
|
||||
* dim_vid(),
|
||||
* bri_vid() - low/high intensity
|
||||
* on_blink(),
|
||||
* off_blink() - blinking chars
|
||||
* ul_start(),
|
||||
* ul_stop() - start/stop underline
|
||||
* save_cursor(),
|
||||
* retn_cursor() - remember/restore current cursor location
|
||||
* ins_line(),
|
||||
* del_line() - insert/delete screen text line
|
||||
* on_cursor(),
|
||||
* off_cursor() - hide/show cursor
|
||||
* vm_on(),
|
||||
* vm_off() - "Video Mode" commands
|
||||
* pixel(x,y) - draw pixel at x,y (video coords, x <= 159, y <= 99)
|
||||
* no_pixel(x,y) - erase pixel at x,y
|
||||
* ldraw(x1,y1,x2,y2) - draw/ erase graphics line, see discussion for box
|
||||
* lwipe(x1,y1,x2,y2) - range for video coordinates as for pixel
