1.8.3 ROW SEARCH Instruction (TBLSRL)
„ Outline
The TBLSRL instruction searches for the column element of the file register table specified
by the table name (Table Name), row number, and column number. If there is data that
matches the data in the specified register (Search Data), the instruction reports that row
number. The type of the data to be searched is automatically determined according to the
specified table.
If errors such as invalid table names, invalid row numbers, invalid column numbers, or
insufficient storage register data length are found, they are reported.
Upon normal termination, if a matching column element is found, 1 is set in the search
result, the row number is set in the [Output], and the [Status] is turned OFF. If no matching
column element is found, 0 is set in the search result.
When an error occurs, the corresponding error code is set in the [Output], and the [Status] is
turned ON.
