#include <stdio.h>

int shl(int,int);

int main( void )
{
  printf("%d", shl(0x100, 2));
  return 0;
}    

format MS COFF

include 'MACRO\PROC32.INC'

public _shl

section '.text' code readable executable

proc _shl c, a, b
      mov     eax, [a]
    mov     ecx, [b]
    shl     eax, cl
     ret
endp    

I was wondering if the MACRO thingy also comes with the linux version for fasm. I don't seem to have it on mine.
