25 CHARACTER STRING FUNCTIONS
25.7 Replacing Character String
• The value input to (n2) specifies the number of the head character position of a character string to be replaced.
Ex.
When the value input to (n1) and (n2) is 5
• A value input to (s1) and (s2) is the STRING type data value and within the range from 0 to 255 byte(s).
• A value input to (n1) is the INT type data value and within the range from 0 to 255. (However, the value must be within the
number of characters of the character string to be input to (s1).)
• A value input to (n2) is the INT type data value and within the range from 1 to 255. (However, the value must be within the
number of characters of the character string to be input to (s1).)

Operation result
1.
Function without EN/ENO
The following table lists the operation results.
2.
Function with EN/ENO
The following table lists the execution conditions and operation results.
*1 When FALSE is output from ENO, data output from (d) is undefined. In that case, modify a program so that the data output from (d) is
not used.
(1): Head character position of a character string to be replaced n2: 5th character
(2): Number of characters to be replaced n1: 5
