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 proprietary and open source interpreters for REXX are available on a wide range of computing platforms, and compilers are available for IBM mainframes.
REXX is also spelled:
- Rexx
- REXX
- but the primary official spelling is REXX and is the spelling used here on Rosetta Code.
The REXX language was influenced by the computer programming languages: ALGOL, PL/I, EXEC, and EXEC 2.
Versions of REXX:
- ARexx is a classic REXX implementation (with extensions) for the AmigaOS, given in bundle since AmigaOS 2. (Regina REXX has specific support for the extended functions that were introduced in ARexx.) ARexx was written in 1987 by William S. Hawes.
- Brexx a classic REXX written by Vassilis N. Vlachoudis, it is free and it's open source and available under the GNU General Public License.
- CRX REXX (Compact REXX) is a classic REXX first written by Dr. Brian Marks.
- CTC REXX is a classic REXX that is bundled with PC/SPF and written by Command Technology Corporation, a license is required to use this product. This version of REXX can only be used under PC/SPF and it's panels. PC/SPF resembles the IBM program product SPF (which has other names and versions).
- KEXX is a subset of REXX that is bundled with KEDIT and written by Keven J. Kearney of Mansfield Software Group, Inc., a license is required to use this product. KEXX only executes under the KEDIT licensed product. KEDIT is an XEDIT clone (an editor from IBM for VM/CMS program products).
- MVS/TSO REXX is IBM's implementation of classic REXX, a license is required to use the product as well as the operating system it runs under; MVS and TSO are used here as generic references.
- MVS/TSO REXX compiler is an IBM implementation of classic REXX, a license is required to use this product as well as the operating system it runs under.
- NetRexx is IBM's variant of the REXX programming language to run on the Java virtual machine. It supports a classic REXX syntax, with no reserved keywords, along with considerable additions to support Object-oriented programming in a manner compatible with Java's object model, yet can be used as both a compiled and an interpreted language, with an option of using only data types native to the JVM or the NetRexx run-time package. The syntax and object model of NetRexx differ from Object REXX and Open Object Rexx.
- Object REXX is/was an object-oriented scripting language initially produced by IBM for OS/2. It is a follow-on to and a significant extension of the "Classic Rexx" language originally created for the CMS component of VM/SP and later ported to MVS, OS/2 and PC DOS. OS/2 version of IBM Object REXX is deeply integrated with SOM. On October 12, 2004, IBM released Object REXX as open source software, giving rise to Open Object Rexx (ooRexx).
- ooRexx (Open Object Rexx) is an implementation of Object REXX, which is REXX with OO features (some REXX programs are compatible).
- OS/2 REXX is a classic REXX that is an IBM implementation of classic REXX, a license is required to use this product as well as the operating system it runs under.
- OS/400 REXX is an IBM implementation of classic REXX, a license is required to use this product as well as the operating system it runs under.
- PC/REXX is the first classic REXX implemented outside of IBM mainframes, intended for IBM DOS and MS DOS. Written by Mansfield Software Group, Inc., REXX was bundled with KEDIT, a license is required to use this product.
- Personal REXX is a classic REXX that is intended for IBM DOS and MS DOS, written by Charles Daney of Quercus Systems, a license is required to use this product. It is also known as REXX/Personal.
- Portable REXX (see the R4 REXX entry, below).
- Regina REXX is an implementation first created by Anders Christensen (in 1992) and is now maintained by others, notably Mark Hessling. Regina REXX runs on more different platforms than any other REXX, too many to name here. It can be downloaded freely.
- Reginald REXX is a REXX developed by Jeff Glatt. It can be downloaded freely.
- REXX/imc a classic REXX developed by Ian M. Collier (imc) for Linux/Unix.
- REXX/Personal is another name for Personal REXX (see above).
- ROO oo-REXX an object-oriented REXX developed by Keith Watts of Kilowatt Software, Inc. It can be downloaded freely. ROO is also known as ROO!.
- R4 REXX a classic REXX developed by Keith Watts of Kilowatt Software, Inc. It was also known as Portable REXX. It can be downloaded freely.
- T/REXX, a REXX compiler for CMS is an implementation of classic REXX written by Leigh Lundin and Mark Woodruff (according to Wikipedia).
- VM/CMS REXX is an IBM implementation of classic REXX that was first implemented (for general use) in the early 1980s. A license is required to use this product as well as the operating system that it runs under. This was the original implementation of REXX written (circa 1979) by Mike Cowlishaw of IBM.
- VM/CMS REXX compiler is an IBM implementation of classic REXX, a license is required to use this product as well as the operating system it runs under.
[Most of the entries were entered mostly from memory and apologies are offered for not knowing more about what wording should be used; the IBM operating systems or Program Products that run REXX are numerous and varied. Their complete (official) names would fill a pageful or two. Some of the REXXes are no longer sold nor available for downloading or purchase, others are no longer maintained. Naming of names is being avoided (especially those licensed products for sale), and it is hoped that this is seen that no products nor vendors are being endorsed, appraised, or critiqued.] -- Gerard Schildberger 09:28, 1 July 2012 (UTC)
