VASM macros/equates for registers

[jotd]

Hi


I'd like to use a letter (like A) for a register (D0)


I've tried a macro:


A:MACRO
D0
ENDM


and an equate


A = D0


but it doesn't work at least on vasm. Is it possible? I don't want to manually replace all "A"s (or CCR/SR => CCR) manually.

Have you tried :
A equr D0

This is pretty standard.

No I didn't, but I will. Thanks. anyway this Z80 to 68000 conversion project is flawed... More in another post.

Yup... If I understand what I think you are doing then it will be flawed.

You dont need to replace registers manually. You can use CED for this job. I often replaced hundred registers in some routines. I used next method, if i want f.e to replace D7 with D5, at first i replaced all D5 with D8. Later all D7 with D5, and at end all D8 with D7. Then you can replace all (A) with (D0) without problems, maybe you can need 2-3 passes only, you can replace "A," with "D0," and ",A" with ",D0" etc.

yes but I have "A" in comments to (original Z80 register name), and I don't want to change that.

I don't think it matters much now anyway... But thanks it works. Will be handy at some other moment. Sorry, googling for asm syntax is so complex...
