Does anybody have any code to sort an array of bytes? I've looked around, and it's mostly to sort dwords, and I cant seem to convert it

Hy, it was easy to convert 4byte bubblesort to 1 byte, here you are:

Code:

; 
; bubble sort 
; input: edi = pointer to byte array, ecx = number of indexes 
; output: edi = pointer to sorted array 
; destroys:  al, edx, eflags 
; 
bubblesort0b: 
       lea     ebx,[edi+ecx] 
     mov     al,[edi] 
.cmploop:dec   ebx
       cmp     al,[ebx] 
   jle     .again 
      xchg    al,[ebx] 
.again:  cmp   ebx,edi 
     jnz     .cmploop 
stosb
loop bubblesort0b 
ret

What an evil matrix.
So now you've reached your goal and you won't post anymore? (Don't dare answer me, you'd ruin it all)
