This course covers the concepts needed to design, or code, applications that use the Virtual Access Storage Method (VSAM). It begins with an overview of VSAM, describes what VSAM does for application programs that request its services, the four types of VSAM datasets, followed by a detailed explanation of the VSAM entry-sequenced dataset. The course then examines the physical organization of a VSAM ESDS, including a close look at a control interval. The structure and components of a KSDS is discussed, which leads to the introduction of the third type of VSAM dataset -RRDS. How an RRDS can be accessed and how VSAM allows random access to records in an RRDS is also covered. The course ends with a description of the appropriate applications for relative record datasets. This course is not written to a specific version. People wishing to learn more about MVS/ESA
