Synopsis

Because software and not hardware is now the dominant cost in computing, users of mainframes will not trade them in for computers with modern design features incompatible with their software. This underlies the demand for the Job Control Language (JCL) program which provides the means of communication between an application, the operating system, and the hardware. In this fourth edition, JCL features that are no longer supported by IBM or are known to cause problems in distributed environments are separated out in a chapter on "obsolete technology" in legacy systems. Further updates for this edition include: changes in architecture, hardware, devices, and terminology; the addition of more tutorial aimed at readers coming from a PC background instead of a mainframe background; an explanation of JCL's role in batch programming and production jobs; new sections on programming in multi-platform systems and on operating system facilities; and examples that reflect concerns like Y2K and security.

A propos du livre

Quatrième de couverture

Revised and updated! The internationally bestselling guide to JCL programming for today′s enterprise programmers and developers

This book helps you take advantage of the current market demand for JCL programmers. Whether you are a member of a Y2K retrofit team, an application manager charged with running secure e–commerce servers off of mainframe data, or a programmer assigned to writing interfaces between a mainframe and a client/server network, there is no faster, easier way to master this difficult programming language.

More user–friendly for PC programmers than previous editions, System 390 JCL, Fourth Edition features:
∗ Many new examples focusing on the concerns of PC programmers
∗ New sections on programming in multiplatform environments
∗ Thorough review of changes in the latest versions of JCL and OS/390
∗ Extensive coverage of JCL in batch programming and production jobs
∗ A separate chapter on obsolete features that can trip up retrofit teams
∗ Chapters on Linkage Editor, IBM utilities, Sort/Merge utility, VSAM, TSO/E, ISPF, and REXX
∗ Helpful chapter–end exercises that you can run on a PC

Combining all the features of a tutorial for programmers new to JCL and a handy, everyday programming reference, System 390 JCL, Fourth Edition is truly the "JCL Programmer′s Bible."

Présentation de l'éditeur

This authoritative guide to JCL has sold over 200,000 copies. The fourth edition has been revised and updated to reflect the recent changes in the language and its emerging applications, including mission–critical coverage of the two most talked about topics in the field, Year 2000 retrofitting of legacy systems and secure e–commerce. Reformatted to match the profiles of today′s programmers, this edition places new emphasis on providing guidance for programmers with a PC background. JCL features no longer supported by IBM have been gathered in one chapter on obsolete technology for use by those maintaining legacy systems. The book also features updates for the latest version of OS/390, including changes in architecture, hardware, devices, and terminology.
