1.8 Table Data Manipulation Instructions
1.8.1 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.
