XHarbour

xHarbour is a free multi-platform extended Clipper compiler, offering multiple graphic terminals (GTs), including console drivers, GUIs, and hybrid console/GUIs. xHarbour is backward-compatible with Clipper and supports many language syntax extensions, greatly extended run-time libraries, and extensive third party support.

Like most dynamic languages, xHarbour is also available as a scripting language (standalone application, linkable library, MS ActiveScript engine [Windows Script Host, HTML, ASP]) utilizing an interpreter written in the xHarbour language.
