I had a play with a 16C84 several years ago and I now need to make it do
something. I am a real PIC beginner. My simple programming question is how do
I represent a byte out to the PORTB of the 84. It seems my restriction is
using a variable in the bsf op code. I manually did it by doing each bit but
I am sure there is a more elegant way of doing it through a loop. I am using
gpasm-0.9.14 alpha (Linux) to assemble my code.

   movlw 0x01
   subwf TmpByte,w
   btfsc STATUS, Z
   bsf   PORTB,0

   movlw 0x02
   subwf TmpByte,w
   btfsc STATUS, Z
   bsf   PORTB,1

......

   movlw 0x80
   subwf TmpByte,w
   btfsc STATUS, Z
   bsf   PORTB,7
