EGA Lines                                             Alt + F9
 This command  toggles  the  display  between 24- and 43-line
 modes (on an EGA) or 25- and 50-line modes (on a VGA).

 With  the  number of lines  increased, you'll be able to see
 more on the screen when you're in the Commander.

    Note:  On some  systems, the  ANSI.SYS  driver (loaded in
           the CONFIG.SYS file) will  limit  DOS's  output to
           the first 25 lines of the screen. If  you  want to
           use  more  lines, you  can  remove  ANSI.SYS  from
           CONFIG.SYS.
