Description
2820H There is no NULL code (00H) in each setting area specified by (s1) to (s28) in the device/label memory.
There is no NULL code (00H) in each setting area in the device/label memory in the device specified by (d) and later.
2821H The device numbers are overlapping between (s1) to (s28) and (d).
3405H The number of characters in the strings input to (s1) to (s28) exceeds 16383.
The number of characters in the strings input to (s1) to (s28) is 0.
The number of characters of the character string in the device specified by (d) exceeds 16383.
3406H The entire string after concatenate processing cannot be stored in the setting area specified by (d) in the device/label memory. (The
number of required points is insufficient.)
