Turbo Pascal

What is Turbo Pascal?
Turbo Pascal is a Pascal dialect developed by Borland Software Corporation under the direction of Philippe Kahn. The software development system includes a compiler and an integrated development environment (IDE) for the CP / M, CP / M-86 and DOS compatible Pascal programming language. Three versions of Turbo Pascal were released for free - versions 1.0, 3.02, and 5.5 for DOS. Turbo Pascal is also known as Borland Pascal.
Turbo Pascal was a development system for the Pascal programming language. It was published and distributed by Boland International for MS-DOS and later for Windows in the 1980s and 1990s. The package contained an integrated development environment, which consisted of a combined editor, program compiler and an execution environment for compiling, debugging and developing Pascal source code.

Early versions were relatively simple, but later versions introduced object-oriented programming and had features such as conditional compilation, compilation of segment units, and the execution of programs. Version 5.5 for Mac included an expanded version of the Object Pascal syntax. Turbo Pascal eventually became obsolete and was replaced by more dynamic and powerful versions - Delphi for Microsoft Windows and Kylix for Linux operating systems.
