Thank you Ralph. Now I understand that I can make the pic "remember" 64 things if necessary. By the way, I just read your post about overclocking a pic. We have been doing it at work for 2 years. We run a 4MHZ pic with an 8MHZ resonator and never had any problems. The circuit is low-volume - only about 5 or 10 pieces per week, so that's not to say there will never be a problem. Thank you. - Peter
