Hi all,

First of all, I would like to compliment privalov on FASM. It has a really wonderful preprocessor.

I would like to buid a macro that would enable me to write something like:

Code:

macro case a_dwdValue,[args]
{
    forward
        cmp a_dwdValue,args
        je .args1
}

Where args1 would be the argument after args.

The use would be something like

Code:

     mov eax , [esp + 4]
     case eax,15,Found0,20,Found0,30,Found1,35,Found2,NotFound

Is there any way to accomplish this?

something like this?

Code:

macro case var,[val,lbl] {
forward
   if ~lbl eq
        cmp     var,val
        je      lbl
   else
        jmp     val
   end if
}
case eax,15,Found0,20,Found0,30,Found1,35,Found2,NotFound

Thanks a lot!!! I didn't know this would work.
I am currently working in one (of the many) OO macros (with polymorphism and possibly exception handling for win32).
This will help me a lot.
