Third parties also made Libraries, but the programmer could also create its own library or enhance the existing ones. When you missed a feature, an interface, or whatever you could program, that yourself and the extension made a reusable part of your toolbox. One of the language’s features: the possibility to link ‘C’ and machine language objects made it a virtual unlimited expandable environment. As a result, Clipper was left of the race to the evolution of programming language.Īnother reason for the decline of Clipper was that Clipper 5.0 was crashed frequently and unpredictably. In the early 1990s, Clipper failed to transition from MS-DOS to Microsoft Windows under the new ownership. Also, in November 1991, the New York Times reported the company’s success in “painstakingly convincing Soviet software developers that buying is preferable to pirating.” According to the article, Clipper had sold 2,000 copies in the Soviet Union.

Upon its establishment, the Nantucket Clipper is basically proposed to be the best complier for dBase existed. They came up with the idea of creating a compiler and start a company to market it. It was told that the two friends Barry and Brian, were having lunch at a restaurant called “Seafood Nantucket Lighthouse,” discussing how the low processing speed of dBase compared to complied applications was striking. The language is now being actively implemented and extended by multiple organizations like XBASE++ from Alaska Software and Flagship and a free project like Harbour and xHarbour. Still, it added the element of C programming language and Pascal programming language and OOP, and the code-block datatype to become far more powerful than the original. Later, it was sold to Computer Associates.Īs a product matured, it remained a DOS tool for many years. It was wrapped into object code, which gives the impression that it was compiled into native code.Ĭlipper was created by Nantucket Corporation, led by Barry Rebell and Brian Russell. Compiling dBase code changed it from interpreted code, which must be interpreted every time each line of code is executed, to p-code, which is used as a virtual machine to process the compiled p-code, is considerably faster, but still not as fast as the machine code generated by native compilers. It was very popular as a database language at the time. History of ClipperĬlipper was created in 1985 as a compiler for dBase III. XBase is the generic term for all programming languages derived from all the original dBase programming language and database formats.
