Use:           fint gds_rhed ( fchar set, gds_coord **cinfo);

               set      = Name or handle of set.
               cinfo    = structure receiving coordinate information from set.
               gds_rhed = GDS result return code.
               
Description:   This function is used by the other GDS routines, such as the
               coordinate routines. For efficiency the coordinate information
               is cached. If it is necessary to have the latest version of
               the information, gds_frhed can be called to clear the cache.
