marshalling
     
         (US -ll- or -l-) The process of packing one
        or more items of data into a message {buffer}, prior to
        transmitting that message buffer over a communication channel.
        The packing process not only collects together values which
        may be stored in non-consecutive memory locations but also
        converts data of different types into a standard
        representation agreed with the recipient of the message.
