> I just use table reads on the 18F series

Wrote a table macro, keeps the listing a bit tidier. Seems to be
OK so far

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

Use as eg    display calib

;retrieve characters from memory

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

;data strings padded to even number of characters with FF terminator

compress data "Compress",0xffff
serial   data "Serial port",0xffff
calib    data "Calibrate",0xff

;macro - display contents of W on LCD via write_d entry point

dispw    macro
         call    write_d
         endm
