When I was young i loved 6502. Instructions there were designed by
programmers not from hardware developers. It was a pleasure to write
programs for this chip in assembler. I used an assembler that had only one
instruction of jump somewhere and decided itself which one used.
There was an addition (third) run but who cares? Why Microchip doesn't offer
such possibility? We all could forget about BRA and GOTO...
It's a pity that micro based on 6502 is now produced by two producers only.
There is no way how to purchase them in Europe.
Maybe, it's off of the PIC topic but comparing 16 and 18 versions it's
possible we will obtain a fully software stack, a couple of address mode in
a next version and will be happy using instructions invented couple years
ago.

Sorry for interuption.

Igor

BRA is better as long as its +-1Kword range is good enough.  In effect,
this means use BRA for jumps within a module, and GOTO for jumps between
modules.
