25 CHARACTER STRING FUNCTIONS
25.2 Extracting Character String Data from the Left/Right
• RIGHT(_E)
Ex.
When the value input to (n) is 5
• A value input to (s) is the STRING type data value and within the range from 0 to 255 byte(s).
• A value input to (n) 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 (s).)
■
Operation result
1.
Function without EN/ENO
The operation processing is executed. The operation output value is output from (d).
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.
Operation error
There is no operation error.
These functions output the data for the specified number of characters from the right of a character string input to (s) from (d).
The value input to (n) specifies the number of characters to be extracted.
(1): Number of characters to be extracted (L): 5
