Neil,

you didn't say which PIC. I wrote this macro for 18F

http://www.piclist.com/techref/microchip/HV_PWM_Proto.htm

;macro

display  macro   var          ;load TBLPTR with string address
         movlw   upper(var)
         movwf   tblptru
         movlw   high(var)
         movwf   tblptrh
         movlw   low(var)
         movwf   tblptrl
         tblrd*+
         call    get_txt      ;get and display characters
         endm

;example

         display title1

;look-up

get_txt  movfw   tablat       ;get characters until
         btfsc   wreg,7       ;W > 0x7f (ie FF terminator)
         return
         dispw                ;print W
         tblrd*+
         bra     get_txt

;data

 org strings

title1   db "* t1---------- *",0xff
title2   db "* t2---------- *",0xff
etc
--=20
