Clipper (programming language)
From Just Solve the File Format Problem
Clipper was a compiled programming language derived from the dBase programming language. Beginning as a dBase compiler, it evolved into a distinct programming language in its own right. In contrast to the original dBase, which ran as an interpreted language, Clipper is compiled into "p-code" which runs on a virtual machine. This is wrapped into .obj files to appear to be native machine code.
Clipper had wide use for business applications in the late 1980s and early 1990s, and there continue to be compatible compilers around such as Flagship.
