   Is that a compliment?  :-)

   One advantage to "by the book" coding compared to your code   
   above, is that in 5 years when I need to make a modification,   
   it is easily understood what the code is doing, and I don't   
   have to re-learn why I coded it that way.   
      
   However, if I need the extra bytes for the boot loader, your   
   code is an advantage over mine.   
      
   Thanks,
