    PURPOSE:    Client side of RPC distributed application 
 
    FUNCTIONS:  main() - binds to server and calls remote procedure 
 
    COMMENTS:   This version of the distributed application that 
                prints "What a dynamic, world" (or other string) on 
                the server features a client that manages its connection 
                to the server. It uses the binding handle dynept_IfHandle, 
                defined in the file dynept.h.
