/sys$common/syshlp/helplib.hlb RENAME, Qualifiers, /EXPIRED  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Modifies the time value specified with the /BEFORE or the /SINCE
    qualifier. The /EXPIRED qualifier selects files according to
    their expiration dates. (The expiration date is set with the SET
    FILE/EXPIRATION_DATE command.) This qualifier is incompatible
    with the /BACKUP, /CREATED, and /MODIFIED qualifiers, which also
    allow you to select files according to time attributes. If you
    specify none of these four time qualifiers, the default is the
    /CREATED qualifier.
