Hello All,
I'm trying to find commonly used math expressions in my PIC
programming.  How do the majority accomplish the following:

if a>b call greater_than
if a<b call less_than
if a=>b call eq_or_gr
if a=<b call eq_or_less

and also:
if a>b AND c>d then call _and_
if a>b OR c>d then call _or_

What I'm using right now is a rather terse method of writing a
single bit then refering to it to check for 'and'/'or'.  Could
someone please mail me some code explaining the above?
Thanks in advance.
Gerry
