7.8 String Processing Instructions
Processing details
• These instructions extract (n) characters of data from the right of the character string data (the end of the character string)
stored in the device number specified by (s) and later, and store the extracted data in the device number specified by (d)
and later.
Ex.
When (n)=5
• The NULL code (00H) indicating the end of a character string is automatically added to the end of the character string data.
• When the number of characters in the device specified by (n) is 0, NULL code (00H) is stored in the device specified by (n).
Operation error
(1) ASCII code (5th character)
Error code
(SD0)
Description
2820H
There is no NULL code (00H) in each setting area in the device/label memory in the device specified by (s) and later.
3405H
An out-of-range value is set to (s).
• The number of characters of the character string in the device specified by (s) exceeds 16383.
• The number of characters of the character string in the device specified by (s) is 0.
The number of characters in the device specify by (n) exceeds that in the device specified by (s).
