Hello,

With FASM, we can use:

Code:

.if eax & ebx | ~edx 

.endif

But I'd like to use instead "&&", "||", "!" (not), "!=" like in C/MASM.

I have tried for example the following:

Code:

&&  EQU  &

But FASM says error Sad

Is it possible to do do it in FASM?

Thanks!!!

You can alter the macro code that does the decoding but the "!" character will not be possible unless you separate it from other characters.

Code:

.if eax || ! ebx ;<--- must have a space before and after "!"

Thanks for the info revolution!

Well, at least it's something good Wink

Any ideas how to define those operators then? I'm quite stuck on it Sad

Have a look at the file if.inc. That is where all the "magic" is done.
