First released in 1983, Turbo Pascal is a comprehensive software development system for the Pascal programming language. It was developed by Borland, and it ran on the CP/M, PC-DOS, and MS-DOS operating systems. Turbo Pascal was the first software development package to include the editor, compiler, and linker All-in-One application.
Turbo Pascal was extremely successful, and subsequent versions also included enhancements for the language itself, making it a unique programming language in its own right. For instance, versions 5.5 and later of Turbo Pascal supported object-oriented programming.
