Processing details
• These instruction convert the Unicode character string in the device specified by (s) to the shift JIS character string, and
stores the converted data in the device specified by (d).
• The Unicode character string in the device specified by (s) should be specified in little endian.
• When a byte order mark is not used, conversion from Unicode to shift JIS occurs as follows.
• When a byte order mark (FEFFH) is added, conversion from Unicode to shift JIS occurs as follows.
Operation error
*1 A two-byte character such as a kanji character represented in shift JIS code should be counted 2.
Error code
(SD0)
Description
2821H The ranges of data in the devices specified by (s) and (d) are overlapping.
