1    /ALL

    Extracts all displays. Do not specify /SCREEN_LAYOUT with this
    qualifier.

2    /APPEND

    Appends the information at the end of the file, rather than
    creating a new file. By default, a new file is created. Do not
    specify /SCREEN_LAYOUT with this qualifier.

3    /SCREEN_LAYOUT

    Writes a file that contains the debugger commands describing the
    current state of the screen. This information includes the screen
    height and width, message wrap setting, and the position, display
    kind, and display attributes of every existing display. This file
    can then be executed with the execute procedure (@) command to
    reconstruct the screen at a later time. Do not specify /ALL with
    this qualifier.
