VMS Help RMS, $DISPLAY  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The Display service retrieves file attribute information about
    a file and places this information in fields in the FAB, in
    XABs chained to the FAB, and in a NAM or NAML block (if one is
    requested).

    Format

      SYS$DISPLAY  fab [,[err] [,suc]]

1 - Returns

    type:         longword
    access:       write only
