The pointer to the current line is set upward (in the direction of the beginning of the workfile) by n records. Since the current line has a fixed position in the window, the text moves downward.

If you do not specify n, the value 1 is assumed.

If n is larger than the number of records (including the top line) before the current line, exaEdit writes

Begin of data

in the dialogue zone and the current line remains unchanged.
