Synopsis

Almost all Cobol software in business use was programmed using outdated versions of Cobol. Although it is no longer supported by IBM, it never got updated because it was used primarily for legacy purposes. However, once the Y2K problem gave everyone a reason to reprogram their mainframes, many companies saw an opportunity to upgrade. Cobol upgrade is an enormous market because everyone is undertaking it at the same time. Most companies with legacy mainframe software have thousands of programs which need to be converted, compiled, tested and reintegrated. Ernst & Young has made upgrade a cornerstone of their mainframe and Y2K consulting practice. They indicate that upgrade efforts begun for Y2K will continue several years into the new millennium so clients can recoup the maximum from their corporate Y2K investment. This text offers a concise primer on how newer versions of Cobol differ from older ones and programming techniques for new features. It also compares three different Cobol products and their compilers in detail. In Part 2 the author walks readers through a comprehensive planning, converting, compiling, and testing scenario for the three upgrade paths possible for current versions. Highlights include: advantages, obstacles, and surprises; compiling converted code; adding /370 programs to existing applications; modifying source programs; special techniques for DB/2 and CICS application programmers; advances in error recovery and performance.

Présentation de l'éditeur

Your roadmap to easier, faster, safer, and more cost–effective COBOL upgrades Successful COBOL Upgrades To keep your valuable COBOL applications alive and reduce costs, you need to upgrade to current standards and get rid of that impossible–to–maintain, obsolete code. This complete guide acquaints you with significant differences between major COBOL releases, describes how to get the most out of the newest features, and boosts your upgrade effort with techniques used by one of the largest Y2K factories in the world–Ernst & Young′s Accelerated Conversion Center. You′ll find step–by–step methods for comprehensive planning, converting, compiling, and testing for each of the three different approaches to upgrading COBOL: manually, using internal staff and resources; using purchased or leased conversion tools; and outsourcing to an established upgrade factory. Important coverage for the success of your upgrade project includes:
∗ Upgrade advantages, disadvantages, obstacles, and surprises
∗ Compiling converted code
∗ A special section on using IBM′s market–dominant tool, CCCA
∗ Adding COBOL/370 programs to existing applications
∗ Modifying source programs
∗ Special programming techniques for DB/2, CICS, ISAM, and Report Writer developers
∗ Working with Language Environment
∗ The latest advances in error recovery and performance
On the enclosed CD–ROM you′ll find:
∗ Handy information on using IBM′s CCCA conversion software
∗ Programs from the book and additional compile procs
