Rexx, invented at IBM around 1980, was one of the first scripting languages. It employs a whole range of techniques to combine two language goals that normally conflict: ease of use and power.

Rexx’s ease of use led to its role as the bundled scripting language of the Amiga OS and OS/2. Its power awarded it the same role on the three major mainframe operating systems–OS, VM, and VSE. Today there are several free Rexx interpreters that run on every machine, from handhelds and desktops to servers and mainframes. We discussed traditional, procedural Rexx in Rexx: Power Through Simplicity.

Open Object Rexx is a 100 percent upwardly compatible superset of "classic" procedural Rexx. Any Rexx script runs under ooRexx. ooRexx adds full object orientation. This includes classes; messaging; objects; single and multiple inheritance; data hiding and encapsulation; operator overloading and polymorphism; and a large, powerful class library.
