            <p>Reads the sequence number of the NC program which is being currently executed in CNC.</p>
            <p>
                If the NC program has no sequence numbers in its all blocks, 
                the sequence number of the last executed block is read.
            </p>
            <p>
                This function is used for watch the block being executed or the current
                process by the application program, or only displaying the current sequence number.
            </p>
            <p>
                The sequence number is stored in "buf.data" with unsigned binary format.
