A gentle reminder: MPALC is a DEAD product. The bug you found will NEVER be fixed. You will be way ahead to change over to MPASM, it's free and can be found on the MCHIPBBS and most all of the PIC ftp sites. MPASM is supported and has on-going improvements. DOS edit is fine, at least a couple of us asked about your editor to make sure that the editor was not part of you problem. Brian Read
