    type:         longword (unsigned)

    display-id argument is the address of an unsigned longword that
    contains the display identifier. All displays that are higher in
    the pasting order (that is, all displays that were pasted after
    the specified display) are deleted as well.

    The display identifier is returned by SMG$CREATE_VIRTUAL_DISPLAY.

    access:       read only
    mechanism:    by reference

    Specifies the pasteboard on which the display deletions take
    place. The pasteboard-id argument is the address of an unsigned
    longword that contains the pasteboard identifier.
