Draft:BRexx
From Wikipedia, the free encyclopedia
BREXX is an open-source interpreter for the REXX programming language, developed by Vagelis Vlachoudis at CERN. It is a faithful implementation of classic REXX, designed to run on DOS-based systems, and is notable for its portability and compact size.[1]

History
BREXX originated as a modified and enhanced version of an earlier public-domain REXX interpreter. Vlachoudis created it in the 1990s to provide a lightweight scripting tool for DOS environments. Over time, it incorporated many standard REXX features and served as a useful scripting engine for command-line automation.
Unlike other REXX variants such as ARexx, which was designed for the Amiga operating system and supported inter-application communication, BREXX remained focused on script execution in single-tasking environments.
Features
- Fully interprets classic REXX syntax
- Runs on MS-DOS, and can be used under Windows via emulation (e.g., DOSBox)
- Small binary size, suitable for embedded or minimal environments
- Includes standard REXX features such as string manipulation, file I/O, and control structures
Applications
BREXX was used within CERN and other scientific environments to automate tasks in DOS-based data acquisition systems. It continues to be used in legacy systems and educational environments where minimal system resources are required.
