Restructured EXtended eXecutor. A programming language for SAA environments.

The estructured Ex tended E ecutor is an interpreted language designed primarily to be embedded in other applications in order to make them consistently programmable, but also to be easy to learn and understand.

Restructured EXtended eXecutor language. A command procedure cum programming language which was initially available on z/VM only, replacing EXEC and EXEC2, but later became an SAA standard. Although SAA is a distant memory, REXX availability in z/OS TSO has seen it replace CLIST as the tool of choice, especially given the fact that TSO, and therefore REXX, can be run in batch. REXX is an effective programming language in its own right with powerful string processing facilities and is used to drive certain program products, notably GDDM. REXX is also available in VSE/ESA, AIX OS/2, Linux and Windows. Although normally interpretive, a REXX compiler and library is available for z/OS and z/VM. REXX for CICS is available for z/OS and VSE/ESA; it consists of REXX Development System and REXX Development System. Object REXX is available for Windows, OS/2, AIX, and Linux for Intel and zSeries 900. See also REXX Language Support.

Restructured Extended Executor. As used with CICS, an interpretive programming language.

Restructured Extended Executor. A general purpose language for end-user personal programming. It is also useful for application macros.

Restructured Extended Executor. An IBM structured programming language used as a general-purpose macro language that sends commands to application programs and to the operating system.

A powerful, easy-to-learn macro language available on most platforms. THE uses REXX as its macro language.

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 commercial and open source interpreters for REXX are available on a wide range of computing platforms, and compilers are available for IBM mainframes.
