Publisher's Synopsis
The internationally bestselling guide to JCL programming for today′s enterprise programmers and developers
A significant upgrade to IBM′s System 390, zOS has simplified the process of setting up and configuring the mainframe while providing improved performance. Along with special features designed for e–business applications, zOS also offers support for 64–bit real storage, improved security, and support for Intelligent Resource Director (IRD). In order to send batch programming work orders to this powerful operating system, programmers can utilize the job control language (JCL). Revised and updated to incorporate these changes, this book will show you step by step all the ways you can use JCL with zOS. This new edition combines an easy–to–follow tutorial for programmers new to JCL and a programming reference for more experienced users. Brown also presents several examples that focus on the concerns of PC programmers as well as sections on programming in multiplatform environments. Other new features to the book include:
∗ A thorough review of changes in the latest versions of JCL and zOS
∗ An extensive coverage of JCL in batch programming and production jobs
∗ Chapters on Linkage Editor, IBM utilities, Sort/Merge utility, VSAM, TSO/E, ISPF, and REXX
∗ Helpful chapter–end exercises
