This is based on my experiences building the CP/M 3 utility programs from the source supplied at www.cpm.z80.de. This site also contains a PL/M compiler, which runs in an ISIS emulator under DOS.
The first thing to do is to get the ISIS emulator set up. I created a file called ENV.BAT, which sets up the correct environment variables for it:
rem These variables are my guidelines, not law :-) rem :F0: should hold the source code rem :F1: should hold the PL/M-80 compiler rem :F2: should hold the ASM-80 assembler rem :F3: should hold the ISIS libraries and emulator SET :F0:=D:\TOOLS\PLM\DIR SET :F1:=D:\TOOLS\PLM\PLM80 SET :F2:=D:\TOOLS\PLM\ASM80 SET :F3:=D:\TOOLS\PLM\UTILS
It should now be possible to use the emulator. The easiest way of doing this is to have scripts that it runs - so you would type ISIS <DATE.MAK, and DATE.MAK would in turn contain:
:F1:plm80 date.plm pagewidth(100) debug optimize :F3:link mcd80a.obj,date.obj,:F1:plm80.lib to date.mod :F3:locate date.mod code(0100H) stacksize(100) :F3:objhex date to date.hex exit
Some of the CP/M 3 build process uses the tools supplied with CP/M - MAC, RMAC, LINK, GENCOM and HEXCOM (instead of objcpm, which isn't supplied, it is necessary to use objhex within ISIS and HEXCOM outside it). The program ZXCC is a miniature CP/M emulator which can run these tools. So where the SUB file reads
MAC DUMPyour script can read
ZXCC MAC.COM DUMP.
