Hi Isaac,

Thanks for the pointer but in this case I was trying to explain the 
fundamentals and in particular why getting to grips with 16 bit arithmatic 
on an 8 bit PIC is a GOOD thing. The whole thing would have been really 
trivial had the OP been comfortable with 16 bit arithmetic in the first 
place.
