FLIP Save and/or restore the Rainbow screen
        
        Flip lets you save the Rainbow screen in a file for later
        restoration.  It does one of three things:

                Saves the screen to a file
                Restores the screen from a file
                Exchanges the current screen with one stored in a file

        Usage:

                FLIP [-w | -r [-d]] [file]

        The file argument specifies where to save/restore the screen
        image to/from.  The default is \FLIP.###.  The -w option means
        to save the screen.  The -r option means to restore the screen.
        The -d option is used with -r and causes the file to be deleted
        after the screen is restored.  If neither -r or -w are
        specified, the current screen is exchanged with the one in the
        file.

        As an example, the file EDIT.BAT might contain the following
        commands

                FLIP -w                 ! Save the screen
                RED %1                  ! Run the editor (sic)
                FLIP -r -d              ! Restore the screen and delete
                                          the file

        If you have a RAM disk, you might want to write the screen
        image there, as it is faster, e.g.

        FLIP -w F:\SCREEN.SAV
        RED %1
        FLIP -r F:\SCREEN.SAV


        BUG - Saving the screen while a key is held down occasionally
        causes the key to repeat or the Shift/Ctrl keys to be in effect
        when the screen is restored (hit another key to stop key
        repeats).  You should avoid any keyboard interaction at the
        moment of saving the screen.
