Written by authors who design, program, and manage online systems supported by VSAM data sets, this text is intended to train readers -- particularly, business data processing programmers -- to use VSAM in a practical manner. Covers thoroughly the VSAM key sequenced data set knowledge and techniques needed to operate productively in the business data processing environment. Illustrates tools in documented source code form -- computational CLISTs, programs that read LISTCATs and automatically extract and analyze them, and prime or alternate key value distribution analysis routines (diskette available for uploading to mainframe). Also addresses management of VSAM data sets in the production environment.
This text overcomes the limitations of most of the technical literature concerning JCL by providing comprehensive examples and practical guidance throughout. The text focuses on the functional, relevant topics programmers need to know to get work done in a business data processing environment. Examples start with what a programmer needs to know to test a job, then builds up to what must be done to move the job into production. This learn-by-doing approach also shows how JCL is integrated with online facilities such as TSO. Features a complete summary of contemporary system completion codes with advice for problem resolutions and fresh coverage of condition code testing, generation data group creation and usage, and more. No Comb binding.
Designed to help newcomers to the TSO/ISPF environment quickly become proficient at creating and editing programs, submitting jobs, and seeing the results. First five chapters provide rapid familiarization with the unique aspects of the IBM terminal device family, logging on and off, the ISPF main menu, and the initial set-up often needed for new accounts. This part of the book can be assimilated in a few hours. Latter five chapters are arranged with examples of the most common way ISO/ISPF is used: for composition of program language code, and composition and submission of job control language to process it. The reader can progress through these chapters performing these processes hands-on, in a self-paced tutorial manner. Reference charts and examples depict a natural flow of the job editing and job submission work.
Revised to be a companion/reference to Gary Brown's System 370/390 JCL, known as the ``JCL Bible,'' it contains a significant amount of actual JCL examples in the context of a single large model program, added upon as each new feature of JCL is introduced. Details the latest enhancements from IBM including MVS/ESA and SMS. Demonstrates debugging techniques through JCL. Illustrations are in TSO/ISPF with JCL to make the book's screen examples look exactly like those seen on a computer.
