You'll learn:
-- the meanings of the critical terms and concepts that apply to VSAM files
-- the COBOL elements for handling key-sequenced, entry-sequenced, and relative-record VSAM files
-- how to handle alternate indexes and dynamic access
-- why error processing is a must for VSAM
-- how to use the Access Method Services utility (AMS) to create, print, copy, and rename VSAM files
-- how to code MVS and VSE JCL to run programs that use VSAM files
-- how your COBOL code is affected if you're working under VS COBOL II

To make learning easier, this book contains dozens of examples of COBOL programs, JCL listings, and AMS job listings. So you'll see how the various language elements interrelate. And you'll have plenty of practical models to use when you're working with VSAM on your own.
