REXX Language Implementation Architecture

Project to develop a modern ground up implementation of a REXX interpreter and compiler, and experiments with language improvements. To implement REXX using the best language tools available today, including the LLVM Compiler Infrastructure. These tools will allow a REXX compiler to be produced supporting multiple backends (including 64 bit architectures).

One aspect of the project is to revisit the REXX language - what can be improved? And most importantly how can it be improved while keeping the essence of REXX:

to make programming easier than before

cREXX will be targeted to run on VM/370 (a nod to REXX's heritage) and it will also run on Linux, Windows, OSX, and z/Architecture.

Please see our project aims.
