Structuring a DDE Conversation In Progress
In a DDE conversation, the Progress client sends and receives data values between Progress fields, variables, and expressions at one end and corresponding data items in the server application at the other end. The client can also send commands to the server using whatever language or format that the server recognizes. The documentation for the server application generally tells you how to set up DDE conversations. This information includes how to address the server from any client, such as Progress. In general, Progress structures all DDE conversations within a standard hierarchy.
