Creation of Turbo Pascal

20 November 1983

Turbo Pascal was a Pascal compiler and development environment from the American company Borland, introduced in 1983 and written largely by Anders Hejlsberg. It combined an editor, a compiler and a debugger in a single small program for personal computers, and the compiler was very fast. At a price of under fifty dollars it was far cheaper than competing products, so it became popular with students and professionals. Philippe Kahn led Borland and marketed it aggressively. Hejlsberg later designed Delphi, C# and TypeScript at Borland and Microsoft. Turbo Pascal helped make Pascal a widely taught language in the 1980s.
