This probably isn't the best way, but I needed to do the same thing the
other day, and I used this

;see if number in a > Const

sub Const    ;Subtract Const from a
jp m,IsGreater ;jump if negitive flag is set

If you need the value again, you can always just add Const again and
you have it back.

Hope this helps
Jeremy
