SjASM Z80 Assembler v0.39g6 Copyright 2006 Sjoerd Mastijn

SjASM version 0.3 is just yet another Z80 cross assembler. Thanks to Eli-Jean Leyssens there is also a Linux version of SjASM.

If SjASM breaks anything - I didn't do it.

• SjASM v0.3x assumes Z80-mode as there are no other cpus supported.
• All calculations are 32 bits.

• '#' Can be used now to indicate a hexadecimal value.
• Local 'number' labels should really work now.
• Multiple error messages per source line possible.
• Things like ld a,(4)+1 work again (=> ld a,5). Somehow I broke this in v0.3.
• Filenames don't need surrounding quotes anymore.
• Macro's can be nested once again.
• Better define-handling.
• 'Textarea' detects forward references.
• Include within include searches relative to that include.
• 'Unlocked' some directives (assert, output).
• '#' Can be used in labels.
• No space needed between label and '=' in statements like 'label=value'.
• The 'export' directive now exports 'label: EQU value' instead of 'label = value'.
• Labelnames starting with a register name (like HL_kip) shouldn't confuse SjASM anymore.
• RLC, RRC, RL, RR, SLA, SRA, SLL (SLI), RES and SET undocumented instructions added.
• "ex af,af" and "ex af" are possible now.
• Added defb, defw and defs.
• Locallabels now also work correctly when used in macros.
• Added // and limited /* */ comments.
• SjASM now checks the label values between passes.
• '>>>' Operator added.
• Sources included.
• '>>>' And '>>' operators now work the way they should (I think).
• Removed the 'data/text/pool'-bug. (Together with the data/text/pool directives. ~8)
• Added endmodule and endmod to end a module.
• STRUCT directive.
• REPT, DWORD, DD, DEFD directives.
• More freedom with character constants; in some cases it's possible to use double quotes...
• It's now possible to specify include paths at the command line.
• Angle brackets are used now to include commas in macroarguments. So check your macro's.
• Fixed a structure initialization bug.
• It's not possible to use CALLs or jumps without arguments anymore.
• DZ and ABYTEZ directives to define null terminated strings.
• SjASM now checks for lines that are too long.
• Added '16 bit' LD, LDI and LDD 'instructions'. (See end of this text:)
• PUSH and POP accept a list of registers.
• Added '16 bit SUB' instruction.
• Unreferenced labels are indicated with an 'X' in the label listing.
• Unknown escapecodes in strings result in just one error (instead of more).
• Labelnameparts now have a maximum of 70 characters.
• Improved IX and IY offset checking.
• Maximum, minimum, and, or, mod, xor, not, shl, shr, low and high operators added.
• Logical operations result in -1 or 0 instead of 1 or 0. Of course, -1 for true and 0 for false ;)
• Fixed the 'ifdef ' bug. (:

• ENDMAP directive.
• DEFM and DM synonyms for BYTE.
• Some bug fixes:
• file size is reset when a new output file is opened.
• 'bytes lost' warning fixed. And thanks to Konami Man:
• PHASE and DEPHASE directives as synonyms of TEXTAREA and ENDT.
• FPOS directive.
• Expanded OUTPUT directive.
• The possibility to generate a symbol file.

New in 0.39g1:

• SjASM now allows spaces in filenames.

New in 0.39g6:

• : Operator.
• MULUB and MULUW work.
• Labels starting with an underscore are listed.
• Can't remember the other changes.

• The listfile doesn't always look that good.
• Commas in strings in macroarguments are not ignored.
• Sourcelines are not further processed after an ELSE, ENDwhatever and the like.
• Using INCLUDE instead of INCBIN isn't detected, and will crash SjASM quite nicely.
• The combination of comments, strings and the af' register can be very confusing for SjASM :)
