/sys$common/syshlp/helplib.hlb NCS Routines, NCS$GET_CS, Description  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The NCS$GET_CS routine extracts the named collating sequence
    from the specified NCS library. If the calling program omits the
    csname argument, NCS creates a collating sequence that uses the
    "native" collating sequence as a basis for the comparisons. This
    collating sequence is padded with NUL characters (hex 0).

    If the calling program omits the librar argument, NCS accesses
    the default NCS library.
