An ESL program establishes itself as a server by:

•Calling DDERegisterServer.

•Passing the DDE application/topic name pair by which it is known.

No conversation is established directly as a result of this call, since it is a client that initiates a conversation.  A server conversation is not established until a client requests a conversation with the application/topic pair registered by that server.  When this happens, a DDE stimulus event is invoked in the server program.
