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

    The NCS$SAVE_CS routine, used in conjunction with the
    NCS$RESTORE_CS routine, permits the application program to store
    a collating sequence definition in a local file or in a database.
    When the calling program specifies the collating sequence
    identifier, NCS returns the location of the definition sequence
    and its length in bytes, permitting the calling program to store
    the definition locally, rather than in a library. Subsequently,
    the application supplies this information to the NCS$RESTORE_CS
    routine, which restores the collating sequence to a form that can
    be used by the NCS$COMPARE routine.

    This routine also does some integrity checking on the collating
    sequence as it is being processed.
