Donald Catto, I made the change to the Sec variable
volatile char Sec;
but it still does not work. Do you thinnk I am missing a header file for it. The program compiles fine. I looked at the header files and the only one I found containing this volatile word is <absacc.h>. I included it, but still does not work.
These are the header files I have included

#include <Reg932.h>
#include <stdio.h>
#include <String.h>
#include <intrins.h>
#include <absacc.h>

Thanks!
