About the Virtual 3270 Interface

The Virtual 3270 Interface allows an external program to communicate with your product, in particular with NCL procedures, using full-screen dialog.

Requests are normally passed to NCL procedures running under the User Services option. The interface user program and NCL procedure can determine the state and flow of data on the conversation as they desire.

This interface may be used to connect to a product region operating in the same or a different VTAM domain.
