Processing details
• These instructions transfer the Unicode character string data in the device specified by (s) to the device number specified
by (d) and later. The Unicode character strings from the one enclosed by double quotes (") or the device number specified
by (s) to the device number containing 0000H are transferred all at once.
(s) 1st character
(s)+1 2nd character
(s)+2 3rd character
(s)+n-1 ''n'th character
(s)+n 0000H
• Even when the device range ((s) to (s)+n)) in which the Unicode character string data to be transferred and the device
range ((d) to (d)+n) for storing the transferred data are overlapping, the processing is performed normally. For example, the
character strings stored in the devices specified by D10 to D13 are transferred to the devices specified by D11 to D14 as
shown below.

2820H There is no 0000H in the setting area specified by (s) and later in the device/label memory.
3405H The number of characters in the Unicode string specified by (s) exceeds 16383.
3406H The entire Unicode string cannot be stored in the setting area specified by (d) in the device/label memory. (The number of required points
is insufficient.)
