System 370/390 JCL Job Control Language (Wiley professional computing)

As the authoritative guide to JCL, this work has been revised and updated to reflect the recent changes in this dynamic field. Continuing the fine tradition of its predecessors, this book explains the MVS operating system and provides readers with the information they need to use it. Major changes have been incorporated, including: the changes caused by the introduction of MVS/ESA; a new chapter on SMS (System Management Subsystem) which is an optional system to manage disk data sets; a chapter on IBM's TSO/REXX which is now SAA's standard procedural language; expanded coverage of VSAM; and a description of CLISTS in the chapter on TSO. Additionally, more short examples have been added in keeping with the author's long-standing belief that short examples eliminate the need for long explanations.
