I get invalid value error. How would I write (esi < edi) to fasm syntax. Nothing I tried worked.


Code:
   .while (esi < edi)
      dec edi
      mov al, [esi]
      mov ah, [edi]
      mov [edi], al
      mov [esi], ah
      inc esi
    .endw     


Thanks in advance

Got it!!! I didn't use .endw properly when I was playing with it.

Code:
    .while esi<edi
      dec edi
      mov al, [esi]
      mov ah, [edi]
      mov [edi], al
      mov [esi], ah
      inc esi
.endw

This probably isn't the best example. I mean, it's just a cmp + jae.

It might not be the best but it's my favorite way to code. After I get good at it than I might learn how to write some macros. I just wanted to see WHILE work in fasm before moving on. I use cmp + jnb and it works well... Jump if Above or Equal put a new twist on things. I'm going play with that one for the next few days.

Thanks rugxulo
