Processing details
• This instruction transfers the character string data in the device specified by (s) to the device number specified by (d) and
later. The character strings specified by (s) or the character strings from the device number specified by (s) to the device
number containing 00H are transferred all at once.

00H
Null character (end of string)
• When 00H is stored in the lower byte of (s)+n, 00H will be stored in both upper and lower bytes of (d)+n.

Error code Description
2820H There is no NULL code (00H) in the setting area specified by (s) and later in the device/label memory.
3405H The number of characters in the string specified by (s) exceeds 16383.
3406H The entire string cannot be stored in the setting area specified by (d) in the device/label memory. (The number of required points is
insufficient.)
