USE THE SYMBOLS IN THE INCLUDE FILE, not hard coded bit numbers. This should be written: btfsc status, c bcf status, c Note the "C" instead of "0". I hope it doesn't need to be said 102 times. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
