Description from the author:
"Rexx/Curses is an external function package for most Rexx interpreters that provides a portable text based user interface for Rexx programs. The underlying portable text based user interface is "curses".
The design of Rexx/Curses follows the C API for Curses as closely as possible.
Rexx/Curses should work on any system that has a curses library available and a Rexx interpreter that supports the REXX SAA API. This covers most Un*x platforms and DOS, OS/2 and Win32.
The recommended curses library for use on Un*x platforms is ncurses, while for DOS, OS/2 and Win32, PDCurses is the curses library required. It is possible to build native X11 applications with Rexx/Curses and PDCurses on Un*x platforms.
Enjoy, Mark."
