Processing details
■Operation processing
• Inserts the character string input to (s2) to the specified position in the character string input to (s1), and outputs the
operation result from (d).
Specify the start position of the character string to be inserted by the value input to n.
After the insertion of character string (s2) to character string (s1), '00H' that indicates the end of character string (s2) is
ignored. If the character string after insertion has over 255 bytes, the character string up to 255 bytes is output.
Ex.
Value input to n is 4
