Since the first edition of our JCL book came out in 1980, more than 165,000 programmers have learned JCL from it. Now, we think the improvements to this latest edition, both in the content itself and in the way its organized into paired pages, are going to make training and reference easier than ever before.
From the Author
We know how frustrating JCL can be. You write a program that requires some feature of JCL you havent used before. So you have to dig through the IBM manuals, trying to figure out which of the details apply to your situation. Or you have to copy a co-workers JCL without understanding it, crossing your fingers that the job will run. Or you have to consult the resident JCL guru in your shop, who tells you one secret at a time. Once you finally figure out a way to handle the JCL, you do it the same way forever
no matter if its the best way or if you know how it works.
But Murachs OS/390 and z/OS JCL ends the frustration and lets you reach a new level of professionalism in a minimum of time. It takes a practical approach to JCL that zeroes in on everyday jobs, so you can learn to code significant job streams in a hurry. Its filled with syntax and examples, so you have plenty of guides for coding JCL on your own. And all the content is presented in our distinctive paired-pages method that saves you so much training and reference time, youll wonder how you ever got along without it.
