7 APPLICATION INSTRUCTION
7.6 Character string operation instruction

• When (s2)+1 (the number of characters to be extracted) is "-1", the entire character string stored in (s1) and later is stored
to (d) and later.
When handling character codes other than ASCII codes, note the following points:
• The number of characters is handled in byte units (8 bits). Accordingly, in the case of character codes in which 2 bytes
express 1 character such as shift JIS codes, 1 character is detected as "2".
• When extracting characters from a character string including character codes in which 2 bytes express 1 character such as
shift JIS codes, consider the number of characters to be extracted in units of character codes for 1 character. Note that the
expected character code is not retrieved if only 1 byte is extracted out of a 2-byte character code.
