orgams | The Amstrad CPC news portal

Madram, Drill and Hicks have released a new version of ORGAMS – an assembler for Z80 assembly language, which runs on the Amstrad CPC. It is a ROM based assembler, so you should use it with a ROM expansion like the X-MEM board by TotO or the Amstrad WiFi. It also features a very detailed english and a french user guide. You can download the latest version from the CPCWiki forums.

ORGAMS assembler

New features

Trace: Source visualization while debugging (imperfect, Orgams can be lost with conditional or repeated blocs)
Trace: Memory visualization while debugging
Trace: CONTROL UP/DOWN for faster navigation
Monitor: Binary display with ‘?’ command
Monitor: Display restored zone when returning to BASIC
Assembler: Can assemble up to #BF80, and in #C000-#FFFF page
Editor: Free cursor
Editor: TAB to repeat previous search (text or label)
Editor: ESC to stop current search (only works with CONTROL F)
Editor: CONTROL-ESPACE put/remove BRK
Editor: CONTROL-C to display CATalogue
Editor: Can join lines (DEL at first column). Corollary : ‘DEL’ after ‘RETURN’ cancels an unexpected split
Editor: Use ‘&’ for hexa, like in BASIC and MAXAM.
Editor: Allow (IX) as shortcut for (IX+0)
General: Use RAM from very last bank (&FF) to alleviate conflict with 256k RAM-DISC.
General: Extension and Monogams ROMs can be burned everywhere (i.e. ROM 1 to 127)
General: Allow |o,”source” (no need to write “.o”)

Bugfixes

Bloc repetition was corrupted when corresponding source was overlapping 2 banks
Division with MSB set in divisor (e.g. &240/&C0) was corrupted
Sign was lost with sub-expression (e.g. -1/[1/1] or -1 mod [4 mod 5])
Negative values for FILL, ORG and repetitions raise error.
Bad expression for repetitions (e.g. undefined label) raise error.
Proper binary save from 9800-HIMEM zone
Returning to basic won’t reset 9800-HIMEM zone anymore
‘ORG &100’ now correctly parsed (not as ‘OR G AND 100’)
Assembling in RSX workzone (e.g. A6FC+) won’t corrupt firmware (Orgams-wise) anymore
Reset CRTC in RESTORE
Mute AY in BRK/RESTORE
At first invocation of BRK/Monogams, select RAM by default (lower & upper)
Robuster memory detection
Fix stack going down at each assemble / editor access.
Numeric pad is active when invoking |m
Block markers properly corrected when importing file
LD B,(IX) doesn’t crash anymore
LD H,IXH doesn’t crash anymore
Miscellaneous search bugs (CONTROL F) corrected.

Madram, Drill and Hicks were working on a new assembler called ORGAMS for the Amstrad CPC and have just released the first version of it. ORGAMS is a ROM based assembler (use it with the great X-MEM by TotO) and is loosley based on DAMS / Turbo Assembler because the authors are using those assemblers. You can discuss the features or ask for help in the dedicated thread in the Push’n’Pop forum. If you understand french, you can also check out the Orgams Wiki. The latest version of the assembler can be downloaded here.
