PEN ON
PEN OFF
PEN STOP
 
    ■ PEN ON      Enables trapping of a lightpen event.
    ■ PEN OFF     Disables trapping of a lightpen event. Even if an
                  event takes place, it is not remembered.
    ■ PEN STOP    Suspends trapping of a lightpen event. Any events
                  that occur are trapped as soon as a PEN ON statement
                  is executed.
 
    ■ The lightpen requires an IBM Color Graphics Adapter.
    ■ The PEN statements are not available for OS/2 protected mode.
