REXX is a (most of the time) interpreted programming language developed by IBM in the end of 70's and beginning of 80's.

REXX is a weakly typed interpreted language - although there are some compilers for it, both for native code and bytecodes. It is mainly used as a glue, script and macro language. There are implementations for most platforms, including some popular portable free software implementations. Also, REXX is the primary scripting language of some platforms, such as VMS, OS/2 and AmigaOS.

It was developed as a personal project by Mike Cowlishaw between 1979 and 1982. Once presented to the public, it was shipped as a product by IBM in 1982. Since then, it is shipped with almost all IBM operating systems.

The language presents various similitudes with , and . Although there is an ANSI specification for the language, there are some popular variants today, such as NetREXX (which is based in the Java platform) and OOREXX, which provides object-oriented syntax and semantics to the language.

As far as a comparison by efficiency, a pretty in depth study from Universit ̈at Karlsruhe can be found here comparing it to , , , and .

Among the modern implementations, some of the most popular are the open source Regina interpreter, OOREXX and NetREXX.
