Description

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

   This routine also does some integrity checking on the conversion
   function as it is being processed.
