REXX

Description

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 IBM mainframe and mini computer 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. 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.
