Working with the phone application scenario

The phone application is used in phase 2 (batch mode), phase 3 (CAF), and interactively in phase 4 (IMS) and phase 5 (CICS®).

The phone directory consists of data from a combination (join) of the employee table (DSN8C10.EMP) and the department table (DSN8C10.DEPT). This joined view is called VPHONE. The program also uses a second view called VEMPLP to update the employee table, which does not affect a view that joins tables.

The phone application is designed to operate in batch and interactively in ISPF/TSO, IMS, and CICS. The following table describes the environments in which each phone application operates and the language in which each is written.
