JCL is an ugly subject. The code is cryptic, there are dozens of parameters that can be coded in dozens of ways, and if you don`t get everything right, your job won`t run.
The trouble is, it`s time-consuming to try to learn JCL using the IBM manuals (which are designed for reference, not training) and confusing to try to use other books (which are barely designed at all). That`s why so many mainframe programmers get by as long as they can with shaky JCL skills.
But our time-tested, best-selling JCL book makes learning JCL as easy and practical as possible for you. So you don`t have to be held back by minimal JCL skills anymore. And because this book is also a reference that`s faster to use than the manuals, you`ll save time whenever you have to brush up on JCL coding details or capabilities.
But this isn`t just a JCL book. It`s a complete guide to your IBM system. Whether you`re working under OS/390, z/OS, or even earlier versions of the operating system, it teaches you enough about mainframe processing so that you`ll know why you code the JCL you do for a given job. And that gives you a measure of confidence and competence that many experienced mainframers lack.
Here`s what you can expect from this book
A fast start
In chapter 2, you`ll see your first complete job stream; in chapter 3, you`ll learn how to create and submit jobs and handle their output; and by the end of chapter 4, you`ll be coding jobs to run your own application programs.
Professional coding models
Dozens of job streams and examples of the coding options for individual parameters guide you in making the right choices as you work with jobs in your own shop.
Paired pages for quick knowledge & reference
All the information is presented in our distinctive paired pages format, with the essential details and examples on the right and the perspective on the left. You read less and learn faster!
An introduction to UNIX System Services
With the proliferation of e-business transactions and web-based applications, IBM mainframes simulate functions that allow them to work as UNIX-based servers. So this book introduces you to the commands and JCL that let you handle files designed for UNIX on your IBM system.
A complete guide to your operating system
and mainframe processing
You won`t just learn JCL syntax and coding details in this book. You`ll also learn how the operating system works so you`ll know why you code the JCL you do for a given job¦and how to code the parameters to make the best use of your system`s resources.
The professional`s desk reference
After you`ve used this book for training, the coding models and paired pages make it the best on-the-job JCL reference you`ll find anywhere.
