VMS Help RPC, rpccp, show_mapping, DESCRIPTION  *Conan The Librarian (sorry for the slow response - running on an old VAX)

         The show mapping command shows elements of an endpoint map.
         Each element corresponds to an object UUID, interface
         identifier, annotation, and binding information. The binding
         information contains an RPC protocol sequence, a network
         address, and an endpoint within square brackets
         (rpc-prot-seq:network-addr[endpoint]).

         The endpoint map can be either the local endpoint map or the
         endpoint map of a specified remote host. If entered without
         a remote host address, the command accesses the local
         endpoint map. For the local endpoint map, a show mapping
         command without any options displays all the map elements.
         For a remote endpoint map, map elements are accessible only
         for protocol sequences that are supported on both your
         system and the remote system.

         Note:  To ensure that you can remotely display all
                map elements from every remote endpoint map,
                run the RPC control program on a system that
                supports all of the protocol sequences
                available in your network environment.

         The options list a selected subset of map elements. The - i
         option selects a specific interface, and the -v option
         qualifies the -i option. The -o object selects a specific
         object; you can use from 0 to 32 -o options per command. The
         options work together to specify the subset of elements for
         the target protocol sequence(s).
