NetRexx and The Rexx Language Association



NetRexx code and documentation are available through the The Rexx Language Association (RexxLA)


IBM NetRexx is available as NetRexx open source distributed by The Rexx Language Association.


NetRexx is a programming and scripting language which has been designed to be a simple, effective, and complete alternative to the Java language. With NetRexx, you can create applications and applets for the Java environment faster and more easily than by programming in Java – and you can compile or interpret them, as appropriate. The new -prompt option allows very fast (usually sub-second) compilation or interpretation of most classes.

Using Java classes is especially easy in NetRexx, as the different types of numbers and strings that Java expects are handled automatically by the language. NetRexx classes and Java classes are entirely equivalent – NetRexx can use any Java class (and vice versa).

NetRexx is inspired by two very different programming languages Rexx and Java.  It blends the clean easy-to-learn syntax of Rexx with the robustness and portability of the Java environment. The result is a language which is tuned for both scripting and application development, and is designed for both interpretation and compilation. It is therefore truly general-purpose.

NetRexx makes writing and using Java classes quicker and easier than writing in Java. This is accomplished by taking the simplicity of Rexx and superimposing it on the object-oriented programming concepts of Java classes, methods, and properties.

On June 8th, 2011 IBM NetRexx was provided to The RexxLA to maintain and support.
