As the Y2K crunch gets worse, the need for mainframe-capable remediation programmers is soaring. This book will help any programmer learn the skills they need to take advantage of this once-in-a-lifetime market opportunity. It's a concise tutorial and reference to the mainframe environment for programmers, project managers and analysts involved in Y2K remediation or legacy-to-client/server migration projects. It focuses on a "quick ramp up" for MVC, JCL, CICS and other mainframe functions, and contains extensive coverage of COBOL for Y2K remediation and legacy data migration. The authors build an example COBOL application, complete with Y2K date conversion problems, and demonstrate exactly how to solve those problems.
