Microchip PIC programming question

[DAFLY98]

Hi, I started programming PICS not to long ago 16F84A to be exact. I knew there
were no value compares within the instruction set but now I am in need of some
compare code. I did search the net and ran across a couple using the status
reg. carry and zero bits, but I have found some problems using it. I am doing
16bit compare but I can modify 8bit compare code to work for my needs. any help
will be appreciated

a borrow occurs, and is set otherwise."

In general piclist is great help if you are looking for PIC code.
