8.5 BLOCK CLEAR Instruction (TBLCL)
[Outline]
The TBLCL instruction clears the data of the block element of the file register table specified by a
table name(Table Name), row number, and column number. If the element type is a character string,
space is written. If the element type is a numeric value, 0 is written.
If both the table element leading row number and the table element leading column number are 0, the
entire table is cleared.
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 data is not written.
Upon normal termination, the number of words cleared 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.
