Code:

Bitness =       16 if Bitness=16 BaseReg equ     bp else BaseReg equ     ebp end if         mov     al,[BaseReg+4] ;always ebp

it is possible to replace "equ" with something, if only works with "Bitness=16" and "Bitness=32" without using the separate file?

You can replace the if with match and make bitness an equ.

Code:

Bitness equ       16 match =16,Bitness {   BaseReg equ     bp } match =32,Bitness {   BaseReg equ     ebp }

thank you!

Alternatively:

Code:

Bitness = 16 if Bitness=16   label BaseReg at bp else   label BaseReg at ebp end if

Tomasz, your alternative is the best!

Note that it has a potential problem that you cannot re-define BaseReg for other part of code when it is defined as a label. If such problem occurs, you can get around it with a simple "undefine" macro:

Code:

macro undefine name  { local new    define name new } Bitness = 32 undefine BaseReg if Bitness=16   label BaseReg at bp else   label BaseReg at ebp end if

version with "equ" however is better because it doesn't refer only to addressing.

Code:

push BaseReg ;push (e)bp is possible

Oh, you're right. This is a limitation of fasm 1 engine that I managed to get rid of in fasm g.
