Turbo Pascal is a famous Pascal compiler developed by Borland in 1980. It was the first compiler that also included an integrated development environment (IDE). Because of this, was possible to write code, compile, run and debug it without having to leave the editor and run other tools. Another strength of the Turbo Pascal compiler was his speed. Compared to other compilers at that time was very fast.
Turbo Pascal was developed by Anders Hejlsberg who initially developed and Compas Blue Label Pascal compiler Pascal. It was available on CP / M and MS-DOS platforms. Borland then licensed the core of the compiler and adding user interface and editor. Anders Hejlsberg Borland where he joined the main architect of all versions of Turbo Pascal and the first versions of its successor, Delphi. Anders Hejlsberg is now forking for Microsoft, where he works as the chief architect of C # programming language.
The first version of Turbo Pascal compiler was released in November 1983. Sold $ 49.95 and was very affordable compared to other Pascal compilers. Generated. Com executable files that were also quite fast. This was a consequence quality directly by the compiler generated code. Includes integrated development environment, compiling faster, faster development cycle (edit, compile, debugging), the quality of the generated code and affordability contributed to additional popularity of the programming language Pascal in the 1980s. Then Pascal was also used as the programming language for teaching in secondary schools and universities.
The continued development of the compiler. The later introduced a user interface full screen with pull-generated. Exe files, supported by online instructions for installation and programming object-oriented. Many advanced features have been added to facilitate the development of software. The latest version of the compiler for DOS, Turbo Pascal 7, all that he had to get the most out of a DOS program.
One of the most important contributions to the popularity of the Borland Pascal language is made by an intelligent approach to add some simple extensions of the language that filled the gaps in the standard Pascal. The most important extension was to support the units. Unit is a separate file which can also be compiled separately. Generally, a joint program is divided into logical units that make writing code and development programs easier. Second important extension was to support the strings. Strings are arrays of characters that can be used for anything, not only for character. Borland also adds support for object-oriented programming, access to absolute memory locations, support for interrupt procedures, instructions assembly line, etc.
If you are interested in compiler construction and Turbo Pascal internals you can examine the Turbo Pascal compiler source code. This is not the original source code but a compatible compiler written in Turbo Pascal. This source code can be also used as a great book on compiler design and implementation.
