• The values to be input to (s1) and (s2) are string type data within the range from 0 to 255 bytes.
• The value to be input to n is word (signed) type data within the range from 1 to 255.
(The input value must not exceed the number of characters of character string input to input variable (s1).)
■Operation result
• Function without EN/ENO
An operation is executed and the operation value is output from (d).
• Function with EN/ENO
The following table shows the executing conditions and operation results.
EN
TRUE (Operation execution)
FALSE (Operation stop)
*1 When FALSE is output from ENO, the data output from (d) is undefined. In this case, create a program so that the data output from (d) is
not used.
Operation error
• No operation error occurs.
Program example
■INSERT(_E)
The program which 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).
