An interpreted, procedural structured language that is included with every version of OS/2 1.3 and higher, every version of IBM PC-DOS 7.0 and higher and most modern Amiga OS variants and clones in addition to all current and recent IBM mainframe and minicomputer operating systems.

Although REXX is a generic programming language and can be (and has been) used to construct everything from simple utilities to large business applications, it is primarily used as a scripting or macro language, and as such is unusually easy to learn. The REXX language was created by Mike Cowlishaw of IBM Hursley in 1979 and the first implementation was shipped inside IBM in 1980 and as an external product in 1982, third party implementations started appearing in 1984.

Object REXX is a later version of the language that has been given object-oriented extensions modelled on those present in Smalltalk (IBM's language of choice at the time), while it is mostly compatible with Classic REXX there are some minor differences that mean that most larger REXX programs have to have at the least some modifications to run correctly under OREXX, and this has meant that in the OS/2 world it never gained any real traction. Amiga REXX is a clone of IBM's Classic REXX that has extensions to help its use as a mechanism for application to application and/or inter-application communication, Regina REXX supports those extensions.

Small programs or routines that you can integrate into your own programs or study to learn from, but are not delivered in library form.

OS/2 applications that can be scripted with REXX

OS/2 based application that have explicit REXX support, other software that has some sort of scripting support can sometimes be "hijacked" to use REXX as well by shaping the output of your REXX script to what the application expects.
