Operation processing
• These functions extract the specified number of characters, starting from the specified position of the string input to (s), and
output the operation result from (d).
• Specify the number of characters to be extracted in (n1).
• Specify the start position of the string to be extracted in (n2).
Ex.
When (n1)=5, (n2)=5
• Input a STRING data type value to (s) within the range of 0 to 255 bytes.
• Input an INT data type value to (n1) within the range of 0 to 255, provided that it is within the number of characters in the
string input to (s).
• Input an INT data type value to (n2) within the range of 1 to 255, provided that it is within the number of characters in the
string input to (s).
