Here's some stuff I did to send strings to an LCD.


MsgToLcd macro msg
; Set up table pointers and send a messag to LCD
	movlw	upper(msg)
	movwf	tblptru
	movlw	high(msg)
	movwf	tblptrh
	movlw	low(msg)
	movwf	tblptrl
	call	LcdMsg
	endm

LcdMsg
; Put up a message pointed to by tblprt (u:h:l)
	tblrd	*+		; Read the table character to tablat, then increment tblptr
	movfw	tablat		; Get the character from the table
	addlw	0		; Test w (above may not set condition codes correctly)
	skpnz
	return			; if we just got a zero byte, exit
	call	LcdPutChar	; Go put it on the LCD
	goto	LcdMsg		; Go do next


Here's a string definition:
SignOnMessageL1
	db	"     IQ512",0 ; Line 1 - Message with terminator


And here's a call of the whole mess:

	msgToLcd(signOnMessageL1)
