I have seen a couple of tips and tricks on PIC programming that I am looking for again.. #1 A routine to clear all RAM on startup (16F84) #2 A routine for saving and restoring W,STATUS, etc.. during interrupts.. I suppose I could come up with some on my own... But who wants to re-invent the wheel.. (especialy this early in the morning...) Jason E.
