Hi,
I'm not saying that you won't get any help but since this is a forum for PicBasic you MAY not get the help you're looking for. Something like the PICList may be more suitable if you're "writing" in, or having problems with ASM.

BUT, with that being said, have you selected 16F84 in MPLAB? Configure/Select Device and then point to 16F84.
