Data
Text string Text string data is stored in ASCII
(one byte except for special char-
acters) in order from the leftmost
to the rightmost byte and from the
rightmost (smallest) to the leftmost
word.
00 hex (NUL code) is stored in the
rightmost byte of the last word if
there is an odd number of charac-
ters.
0000 hex (2 NUL codes) is stored
in the leftmost and rightmost
vacant bytes of the last word + 1 if
there is an even number of charac-
ters.
ASCII characters that can be used in a text string includes alphanumeric characters, Katakana and sym-
bols (except for special characters). The characters are shown in the following table.
