Whoops, I just looked at your link.

This is a classic example of what NOT to do.  This is very, very bad.

;*****Set up the Constants****

STATUS         equ       03h                 ;Address of the STATUS register
TRISA             equ       85h                 ;Address of the tristate 
register for port A
PORTA           equ       05h                 ;Address of Port A


DO NOT TO THIS.  Don't ever do this.  Run away from any program that does 
this.
