This attribute sets which line will be the first line displayed in the viewing work area of the PRINTER. For example, if you set the value of TOP LINE to 5, the line that is displayed at the top of the work area is line 5. Line 1 is the first line that is available to be displayed.
The PRINTER widget may adjust your request for displaying the top line to prevent displaying blank lines. You may not set the value of TOP LINE to 0. If you execute a STATUS command to get the value of TOP LINE, and it returns 0, that means that there are no lines in the PRINTER widget.
