I'm looking at Brad Minch's assembler code for the 18f2455, which is
mpasm-ready, but maybe not quite gpasm-ready. I'm trying to see if I
can get it to work with gpasm.
He wrote some interesting macros, which is the reason I'm posting this
question:
Can a macro in gpasm be passed a relational operator (==, !=, <=, >=,
etc.) as a argument, and then use it in a conditional statement? For
instance, can I write:
blah macro relop
if (1 relop 1)
; an equal sign was passed
else if (1 relop 0)
; one of these was passed: !=, >, or >=
endif
endm
Apparently mpasm can handle this, but I'm getting syntax errors from
gpasm on the (1 relop 1) and (1 relop 0) lines.
Let me know if this is not an appropriate place to ask this question!
If it would be helpful I can send a short asm file.
Thanks.
Ben
