Mark: It could be an ICEPIC bug, but before you make that assumption, you should check to be SURE that: 1. You've actually loaded the ICEPIC's program memory with the program whose source code you're single-stepping through. 2. The correct register-page is selected when your "INCF" is executed. 3. An interrupt is corrupting the register in question. -Andy === Andrew Warren - fastfwd@ix.netcom.com === Fast Forward Engineering - Vista, California === http://www.geocities.com/SiliconValley/2499
