REXX
REXX is a programming language originally developed by IBM and over time included in all IBM operating systems (e.g. OS/2, AIX and PC DOS). In addition to this, various IBM and non-IBM implementations have been made available for most operating systems/environments (including free implementations for Win32/Win64, Linux, Mac OS X, Solaris and many others - e.g. Regina, Open Object Rexx). This interface unit makes it possible to inter-mix code written in Pascal with REXX.
