Yes, Jose. You are correct. :)

For Thomas, I would add:

 DT    "HELLO",0

 is equivalent to

 RETLW    'H'
 RETLW    'E'
 RETLW    'L'
 RETLW    'L'
 RETLW    'O'
 RETLW    0

You get each character using table lookup (Microchip app notes and
piclist.com for examples), send it to the LCD (also app notes and
piclist.com), get the next one and so on until you get the RETLW 0. Then
stop.
