thanks i have read a little about configs but still unclear i guess the link will explain more also i pasted your code had the same error as before but code works fine, also this popped up while building


also forgot to mention this is all new to me i haven't created my own code yet i don't know what the variables, configs and commands are and what they can do for any PIC let alone my 44 16f887 demo board ;x
