• RIGHT(_E)
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.
Ex.
When the value input to (n) is 5
"ABCDEF12345"
High-order byte Low-order byte
+0 42H (B) 41H (A)
+1 44H (D) 43H (C)
+2 46H (F) 45H (E)
+3 32H (2) 31H (1)
+4 34H (4) 33H (3)
+5 00H 35H (5)
(1): Number of characters to be extracted (L): 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.
Execution condition
EN
TRUE (Executes operation)
FALSE (Stops operation)
*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.
