5.9.5 Clear Table Block (TBLCL)
( 1 ) Operation
The TBLCL instruction clears the block of data in the table data that is specified by the table name, row numbers, and
column numbers. The elements are filled with spaces if the data type is for text strings, and 0s if the data type is for
numeric values.
If both the first row number and the first column number of the table element are 0, the entire table will be cleared.
If an error occurs when accessing the table, such as data that is outside of the valid range or not enough data length at
the destination, an error is output and no data is written.
If the instruction ends normally, the number of words that were cleared is output and the status is turned OFF. If an
error occurs, an error code is set in the output data and the status is turned ON.
ΠIf the first row number and column number of the table element are both 0, the entire table is cleared.
[ a ] If the Clear Succeeds
[ b ] If the Clear Fails
ΠIf the clear fails, the table data will retain the contents from before the instruction was executed.
