Method Description Code Examples Instruction example
Text strings Text is stored in ASCII (1 byte/
character excluding special
characters) starting with the
lower byte of the lowest word
in the range.
If there is an odd number of
characters, 00 (NULL) is
stored in the higher byte of the
last word in the range.
If there is an even number of
characters, 0000 (two NULLs)
are stored in the word after the
last in the range.
