As an alternative to building your entire service interface from scratch, you can streamline some of the work for CICS and IMS screen service interfaces by capturing one or more workflows. For service interfaces that traverse a large number of screens, a workflow is the best starting point. A workflow stores details of an interactive session with your application via the Workflow Capture emulator, and contains a record of the session showing screens used, values entered, CICS or IMS transactions invoked, keys pressed, etc.
The Workflow Capture emulator is similar to a TN3270 emulator you would use to connect to an application running on an mainframe or on an enterprise server. Similarly, to use access your application via the Workflow Capture emulator, it must be accessible via a connection to a mainframe or an enterprise server.
