Character string operation instruction
■Comparing character strings
*1 The following shows comparison conditions for comparing character strings.
- Match: All characters in the strings must match
- Larger string: In case of different character strings, character string with the larger character code
(If character string lengths are different, the longer character string)
- Smaller string: In case of different character strings, character string with the smaller character code
(If character string lengths are different, the shorter character string)
■Concatenating character strings
■Transferring character strings
