All compares on a PIC can be done with just the w register
as the only temporary. On the PIC parts compares in
general sould be done by comparing individual bytes
whenever possible, A  little attention to detail is worth it.
I believe the MPC compiler has a total of 55 different
code sequences related to 8 and 16 bit compares.
