Author Description

An end-to-end introduction to object-oriented programming with the new release of Object REXX for OS/2 WARP. For years, programmers in IBM environments have used REXX as a quick, easy tool for software development. REXX is OS/2's built-in scripting language. Now, IBM builds on the benefits of REXX by introducing a new, object-oriented version, Object REXX. This is the only complete guide to object-oriented programming with IBM's new Object REXX. Better yet, it comes with a complete working copy of IBM's Object REXX product. Since REXX has a well-deserved reputation for ease of use, learning Object REXX may be the easiest way for procedural programmers to move into object-oriented programming. Learn how Object REXX implements objects, classes, instances, methods, and polymorphism. Walk through the entire application development process. Learn how Object REXX fits into IBM's SOM object model, and how it can be used to securely access IBM DB2 database resources.
