    Default: No dispatch file created.
    Creates the server dispatch table file. An RPCGEN dispatch table
    contains:
    o  Pointers to the service routines corresponding to a procedure
    o  A pointer to the input and output arguments
    o  The size of these routines
    A server can use the dispatch table to check authorization and
    then to execute the service routine; a client may use it to deal
    with the details of storage management and XDR data conversion.
    Mutually exclusive with the /CLIENT_STUBS_FILE, /HEADER_FILE,
    /SERVER_STUBS_FILE, /TRANSPORT, and XDR_FILE qualifiers.
