This subprogram makes it known that the server supports the service specified in DDE-VIEW.SERVICE and the conversations on the topic specified in DDE-VIEW.TOPIC. A client will not be able to establish a conversation with the server until this subprogram is executed. Your client should not try to register the name "Natural" because this is reserved.
Before you execute this subprogram, you must assign the *DIALOG-ID system variable of the server dialog to DDE-VIEW.CONV-ID. You must also assign the string "DLGID" to DDE-VIEW.MESSAGE.
