Operation processing
• These functions concatenate the strings input to (s2) to (s28) to the end of the string input to (s1), and output the operation
result from (d).
• The (s2) to (s28) strings are concatenated successively, ignoring 00H, which indicates the end of the (s1) string.
• If the string after concatenation exceeds 255 bytes, the substring up to the 255th byte will be output.
• Input a STRING data type value to (s1) and (s2) to (s28) within the range of 0 to 255 bytes.
