MPASM lets you make tables of text (string constants in a way) easily
with the 'dt' directive.  For example,
        dt      "Text"
is the same as
        retlw   "T"
        retlw   "e"
        retlw   "x"
        retlw   "t"

As you see above, MPASM will handle the ASCII for you.  The value which
is actually stored is the ASCII code of the letter in quotes.  For
example, "0" converts to 0x30.
