8.1 BLOCK READ Instruction (TBLBR)
[Outline]
The TBLBR instruction consecutively reads file register table elements in block format that are
specified by table name(Table Name), row number, and column number. It then stores the elements in
a continuous region starting with the specified register(Read Data). The type of the element being
read is automatically determined according to the specified table. The type of the storage destination
register is ignored and the read data is stored according to the table element type without converting
the data type.
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 reading 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.
