Techopedia Explains Turbo Pascal

Turbo Pascal was a development system for the Pascal programming language. It was released and distributed in the 1980s and 1990s by Boland International for MS-DOS and later for Windows. The package contained an integrated development environment which consisted of a combined editor, program compiler and execution environment for compiling, debugging and development of Pascal source code.

Early versions were relatively simple, but later versions introduced object-oriented programming and had features such as conditional compilation, segment unit compilation and execution of programs. Version 5.5 for Mac included an extended 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.
