To answer my own question courtesy of Roy in a previous post;

Found this at a microchip forum -

It sounds like you have a 'goto $-1' or similar instruction somewhere in
the module. While that's legal in the 16-series devices, it's not for
the 18-series. In the 18-series devices, all PC-relative branches have
to be made to a location that's an even number of bytes from the current
PC value. 

Rewriting the GOTO instruction fixed the linker error.

code to PIC18

so, looking at the code snippet;

  btfss  stata,3
  bra    $ + 5         <<<<<<<<<<<<< error line
  bsf    Port_A,HAZ
  incf   haz1,1
  btfsc  haz1,0
  bra    $ + 2
  bcf    Port_A,HAZ
  movf   Port_A,0
  movwf  PORTA        ;update the relays

is the solution to write? ;

  btfss  stata,3
  bra    $ + 6        <<<< now an even step
  nop                 <<<< add a nop to align ?          
  bsf    Port_A,HAZ
  incf   haz1,1
  btfsc  haz1,0
  bra    $ + 2
  bcf    Port_A,HAZ
  movf   Port_A,0
  movwf  PORTA        ;update the relays

OK, it works, but is this the correct modus operandi?
