Description
The REXX language is a versatile general-purpose programming language that can be used by new and experienced programmers. This course for programmers who want to learn the REXX language.
That Rexx is easy to learn and use does not mean that it has limited features or is some sort of “beginner’s language.” Rexx competes, feature for feature, with any of the other major scripting languages. If it didn’t, it certainly would not be the primary scripting language for mainframes, nor would it have attained the widespread use it enjoys today on so many other platforms. Nor would there be many hundreds of thousands of Rexx users distributed around the world.*
Ease of use and power traditionally force language trade-offs. It is easy to get one without the other, but difficult to achieve both. Rexx is specifically designed to combine the two. It achieves this goal through these principles:
Simple syntax
Small command set, with functions providing the power
Free-form language
Consistent, reliable behavior
Modularity and structured programming
Fewer rules
Standardization
