Object REXX for OS/2 Warp

Overview

Many OO 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. Object REXX also supports distributed objects written in ...

Overview

Many OO 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. Object REXX also supports distributed objects written in many other languages through Common Object Request Broker Architecture (CORBA) technologies, such as IBM's System Object Model (SOM). This book demonstrates a practical approach to using Object REXX and OO techniques to develop commercial systems to 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, existing SOM-based objects, the OS/2 Workplace Shell, and Internet Web pages. Extensive code examples are provided to illustrate every step.

REXX for Retards

I thought it would probably be best to let this book speak for itself, so I selected a touching interlude from pages 156-157...

"I've put hardly any logic behind the controls, but let's see how it looks," said Steve. He clicked on the Tools run icon and started the application.

"That looks really professional, Steve," commented Hanna as the window appeared on the screen [see Figure 49].

"Now I've got to add the logic," said Steve. "But that really shouldn't be hard, thanks to this directory structure you've set up."

"OK, I'll leave you to it," said Hanna, getting up.

"Just a moment, Hanna," said Steve, rising, too. "There's something I need to tell you." Steve suddenly looked serious, and rather strained. "I've been thinking about this for a while; maybe it's time I settled down and sorted out my life. We've been so busy getting our company going, I haven't had time to think about myself. But now that we've got our first big application installed with two customers and the money is starting to come in..." Steve's voice trailed off.

Hanna felt uneasiness, even panic. Did Steve want to leave? Their little company had only just started to find its feet, and every member of the team was vital to its continued existence. If Steve left at this point, Hacurs company [sic] would never survive. And what did he mean by "settle down and sort out his life?" Was there a woman in his life? Where had he found time? They had all been so busy getting the company going. Hanna's heart started to pound.

"So... what I mean is," Steve struggled on. "Do you want to see the ball game on Saturday?"

A flood of relief swept through Hanna. She laughed involuntarily, and Steve was startled. He might have taken offense, but Hanna's broad smile and shining eyes reassured him that she would very much like to see the ball game on Saturday.

This book actually does have some programmer-oriented content, in between the squabbles, the romance, and the dueling ThinkPads.The premise is rather nice -- teach the principles of object-oriented programming using the Object REXX that is bundled for free with OS/2 Warp. But the presentation is, well, novel.--Dr. Dobb's Electronic Review of Computer Books
