Description
85802-7 Many object-oriented languages seem complicated and alien to programmers familiar with procedural languages, such as COBOL. This book introduces Object REXX, a new OO language that breaks the OO barrier. Object REXX is based on a tried-and-trusted language used around the world today. Because it has the most complete and easy-to-use set of OO features of any language, it offers a simple way for programmers with a procedural background to enter the new world of objects. This book demonstrates a practical approach to using Object REXX and OO techniques to develop commercial systems that meet changing business requirements. It tells the story of how Hanna, Steve, and Curt design and implement a commercial application system step-by-step using object persistence in file systems and relational databases, GUI builders, and Internet Web pages. Extensive code examples are provided to illustrate every step.
