VMS Help LBR Routines, LBR$RET_RMSSTV, Description  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The LBR$RET_RMSSTV routine returns, as the status value, the
    status of the last RMS operation performed by the Librarian.
    Each programming language provides an appropriate mechanism for
    accessing RMS status values.
