| goal=the REXX language is designed to make programming easier; to foster high quality programs by making writing them as simple and enjoyable as possible; designing each part of the language for people to use is more important than providing easy implementation; follows the principle of least astonishment [https://en.wikipedia.org/wiki/Principle_of_least_astonishment (POLA)]. }}
<cite>REXX (REstructured eXtended eXecutor) is an interpreted programming language which was developed at IBM. It is a structured high-level programming language which was designed to be both easy to learn and easy to read. Both proprietary and open source interpreters for REXX are available on a wide range of computing platforms, and compilers are available for IBM mainframes.</cite>▼

* '''[[NetRexx|NetRexx]]''' is IBM's variant of the REXX programming language to run on the Java virtual machine. It supports a classic REXX syntax, with no reserved keywords, along with considerable additions to support Object-oriented programming in a manner compatible with Java's object model, yet can be used as both a compiled and an interpreted language, with an option of using only data types native to the JVM or the NetRexx run-time package. The syntax and object model of NetRexx differ from Object REXX.▼

It is a follow-on to and a significant extension of the "Classic Rexx" language originally created for the CMS component of VM/SP and later ported to MVS, OS/2 and PC DOS. OS/2 version of IBM Object REXX is deeply integrated with SOM. On October 12, 2004, IBM released Object REXX as open source software, giving rise to Open Object Rexx (ooREXX).▼
