„ Outline
The TBLBW instruction writes the contents of a continuous region starting with the speci-
fied register (Write Data) to the file register table elements in block format that are specified
by table name (Table Name), row number, and column number. The data is processed
assuming that the type of the table elements in the storage destination register is the same as
that of the table elements in the storage source register.
If errors such as invalid table names, invalid row numbers, invalid column numbers, or
insufficient storage register data length are found, they are reported and the contents of the
storage destination register is retained without writing the data.
Upon normal termination, the number of words transferred is set in the [Output] and the
[Status] is turned OFF.
When an error occurs, the corresponding error code is set in the [Output] and the [Status] is
turned ON.
