DOWN
The DOWN command scrolls the data display by the specified scroll amount to reveal the data that follows the last line currently displayed. Unless you specify a temporary scrolling value with the DOWN command, the value in the SCROLL field is used. In row mode, DOWN scrolls to reveal the columns that follow the last column currently displayed. To view the next row in the table, issue the NEXT primary command.
