Hello! For a Pic 16F84 device I have this macro routine: inccmp macro reg, limit incf reg, f movf reg, w sublw limit btfsc STATUS, C return clrf reg endm but for the 12C508A device the instruction sublw don=B4t exist. Can any kind person tell me what I have to take for instructions to get the same function! Regards =C5keN -- http://www.piclist.com#nomail Going offline?
