Here's some code I used for outputting text strings on a PIC16...

PrintString macro DataAddr ; Macro to preload data address prior to
calling print string subroutine
	movlw	high(DataAddr)
	movwf	StringPointerHi
	movlw	low(DataAddr)
	movwf	StringPointerLo
	call	PrintStringSub
	endm

;========================PrintString==============================
PrintStringSub
; Pass pointer to string in ROM in StringPointerHi and StringPointerLo.
String is in DT statements, which
; create arrays or RETLW statements.
  cblock
    StringPointerHi
    StringPointerLo
  endc
  	movf	StringPointerHi,w	; get high half of string pointer
  	movwf	PCLATH				; save it for table jump
  	movf	StringPointerLo,w	; get low half
	call	GetTableByte		; go get byte in retlw in w
	addlw	0		; make sure Z is set or cleared based on w
	skpnz
	return			; exit if byte is zero, end of string
	call	Tx232		; Go send the byte
	incfsz	StringPointerLo,f	; move up to next character
	goto	PrintStringSub	; StringPointerLo did not overflow, so we don't need
to increment high byte
	incf	StringPointerHi,f	; bump high byte
	goto	PrintStringSub

GetTableByte
    movwf	PCL		; jump into table. Returns with value in w


HelpString
	dt "! Send data\r\n"
	dt "# Clear log, reset timer\r\n",0


SampleUse
	PrintString HelpString ; output the help string
