Abstract
Virtual Storage Access Method (VSAM) is one of the access methods used
to process data. Many of us have used VSAM and work with VSAM data sets
daily, but exactly how it works and why we use it instead of another
access method is a mystery.
This book helps to demystify VSAM and gives you the
information necessary to understand, evaluate, and use VSAM properly.
This book also builds upon the subject of Record Level Sharing and
DFSMStvs. It clarifies VSAM functions for application programmers who
work with VSAM. The practical, straightforward approach should dispel
much of the complexity associated with VSAM. Wherever possible an
example is used to reinforce a description of a VSAM function.
This IBM® Redbooks® publication is intended as a supplement to
existing product manuals. It is intended to be used as an initial point
of reference for VSAM functions.
