VMS Help System Services, $UPDSEC 64W (Alpha Only)  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    On Alpha systems, writes all modified pages in an active private
    or global disk file section back into the section file on disk.
    Zero or more I/O requests are queued, based on the number of
    pages that have been modified.

    The $UPDSEC_64W service completes synchronously; that is, it
    returns to the caller after writing all updated pages.

    In all other respects, $UPDSEC_64W is identical to $UPDSEC_64.
    For all other information about the $UPDSEC_64W service, refer to
    the help for $UPDSEC_64.

    This service accepts 64-bit addresses.
