	29	* Mini-DDE implementation
	30
	31	Most transactions involve a topic name and an item name (choose these
	32	as befits your application).
	33
	34	A client can:
	35
	36	- ask the server to execute commands (data) associated with a topic
	37	- request data from server by topic and item
	38	- poke data into the server
	39	- ask the server to start an advice loop on topic/item
	40	- ask the server to stop an advice loop
	41
	42	A server can:
	43
	44	- respond to execute, request, poke and advice start/stop
	45	- send advise data to client
	46
	47	Note that this limits the server in the ways it can send data to the
	48	client, i.e. it can't send unsolicited information.
