safe way to use .if

[jj2007]

Is it okay to add this to the GeneSys macro set?

I feel honoured, Paul - please go ahead. It's just a pity that Masm would not accept a .sif...

Thanks and thanks. About MS: It will happen

    .if They_ever_get_around_to_it  == 1

or

   sif They_ever_get_around_to_it  == -1

Here is another option: .if signed eax<0

Code Select Expand

include \masm32\include\masm32rt.inc

signed equ sdword ptr

.data
IsLower   db "Operand is < 0", 0
IsHigher   db "Operand is > 0", 0

.code

;read-only data before start
AppName     db "Test app:", 0
MyVar   dd 0

start:   call TestWin
   invoke ExitProcess, 0

TestWin proc

  mov eax, -123
  .if signed eax<0
   invoke MessageBox, NULL, addr IsLower, addr AppName, MB_OK
  .else
   invoke MessageBox, NULL, addr IsHigher, addr AppName, MB_OK
  .endif

  mov eax, 123
  .if signed eax<0
   invoke MessageBox, NULL, addr IsLower, addr AppName, MB_OK
  .else
   invoke MessageBox, NULL, addr IsHigher, addr AppName, MB_OK
  .endif

  ret
TestWin endp
end start
