Might I respectfully suggest that, since this is a commercial environment,
you get a good quality commercial programmer (Picstart+, Warp-13, EPIC,
whatever) and look at more modern PICs than the 16F84.  16F87x or the
PIC18 family.  Less than a day of your time messing with it will pay for
the hardware.

While I think learning Assembler would be a good idea to get intimately
familiar with the PIC architecture and all, I'd also suggest a C compiler
will probably produce much better results for you much more quickly, since
you're not already an assembler kind of guy.

Just a couple suggestions.
