Hi guys,

Even coding in assembler, I like to have my code as "readable" as possible so... I was wondering if it would be possible to pass function names to the defined ".if" macro. Example:

Code:
; start the party...

  .if ( IsRunning(12) & IsUserRestricted() )

     mov ebx, 1

  .else

     mov ebx, 0

  .endif

; here comes the procedures definitions

IsRunning proc check_param

 ; some code here

 mov eax, 1
 ret

IsRunning endp

IsUserRestricted proc
 
 ; some code here 

 mov eax, 0
 ret

IsUserRestricted endp        


So, the above ".if" would detect that we are passing a function name because of the brackets "( )" and it would generate something like:

Code:
_call IsRunning, 12
cmp eax, 0
jz @ff
_call IsUserRegistered
jz @ff
mov ebx, 1
....    


Thanks!

Are you trying to make assembly look like C? Confused

I think you missed the whole point of assembly! Razz

Too late, I remember this was already done some years ago,

(Maybe not exactly with this syntax, maybe not full-featured, I don't remember exactly, but the idea of function-call-inside-if-macro was already here and was implemented).

PS: FASMLIB "libcall" macro did check for error inside nested FASMLIB function call... but nobody cares :'(
