Clipper Summer 1987
Clipper was a compiler for the Dbase IV product, which allowed programmers to compile .prg files into an executable, that could in turn read Dbase data files. In the 1980's this was a popular way of shipping database applications prior to the rise of Microsoft Access. Clipper applications ran under MS-DOS. As time went by there were even support for various 286 DOS extenders for the original clipper 87 compiler.
