The Common Programming Interface (CPI), one of the four key elements of Systems Application Architecture, comprises a growing set of programming languages and services. The CPI indirectly offers end-user access through the Common User Access by providing the application developer with the necessary interfaces. The CPI addresses the application development requirement for portability of applications and programmer skills. As the CPI continues to expand, it addresses the requirements for access to host data through intelligent workstations and for transparent access to remote data and applications.
