Processing details
■Operation processing
• These functions insert the string input to (s2) into the insertion start position, i.e. the 'n'th character position from the
beginning of the string input to (s1), and output the operation result from (d).
• After the (s2) string is inserted into the (s1) string, 00H, which indicates the end of the (s2) string, is ignored.
• If the string after insertion exceeds 255 bytes, the substring up to the 255th byte will be output.
