Description

This subprogram requests a conversation with a server providing the service DDE-VIEW.SERVICE on the topic DDE-VIEW.TOPIC. If an appropriate server can be found, this starts a conversation identified by a unique conversation ID, which is returned to DDE-VIEW.CONV-ID. If not, this field is empty on return of the request. If you plan on having more than one conversation, store the value of DDE-VIEW.CONV-ID as you will need it to identify conversations.

Before you execute this subprogram, you must assign the *DIALOG-ID system variable of the client dialog to DDE-VIEW.CONV-ID. You must also assign the string "DLGID" to DDE-VIEW.MESSAGE.
