Description

   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.
