Description

   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.
