;* Only CXM_IEVENT messages are passed through the input network. Other types
;* of messages are sent to an optional port in your broker. This means that
;* you must test the message type in your message handling, if input messages
;* an command messages come to the same port.
;*
;* CXM_IEVENT: Messages of this type rattle around the Commodities input
;*	       network. They are sent to you by a Sender object, and passed
;*	       to you as a synchronous function call by a Custom object.
;*
;*	       The message port or function entry point is stored in the
;*	       object, and the ID fied of the message will be set to what
;*	       you arrange issuing object.
;*
;*	       The data section of the message will point to the input event
;*	       triggering the message.
;*
;* CXM_COMMAND: These messages are sent to a port attached to your Broker.
;*		They are sent to you when the controller program ants your
;*		program to do something. The ID value identifies the command.
