This chapter describes the macro-level interface as well as the external interactions between the multiple virtual storage (MVS) system and the TPF system that are required to access VSAM databases from the TPF system. An introduction to VSAM is provided, including terminology that is useful in understanding VSAM database support, which is the term that we will use to refer to the support implemented in the TPF system that permits applications to access VSAM databases.
