                       Microsoft RPC Version 1.0 Alpha
                                October 1991
                               Hello3 Example
    FILE:     hello3\client.c
    USAGE:    client <servername>
              where  <servername> is the name of the server running
                     the server side of the distributed application
    PURPOSE:  Client side of RPC distributed application hello3
    FUNCTIONS: main() - binds to server,
                        calls remote procedure HelloProc2
    COMMENTS:
    This distributed application prompts the user for a string and
    calls a remote procedure that displays that string.  The client
    manages its connection to the server using the binding handle
    hRpcHello that is defined in the file hello3.h (from hello3.acf).
