Pascal is a historically influential imperative and procedural programming language, designed in 1968–1969 and published in 1970 by Niklaus Wirth as a small and efficient language intended to encourage good programming practices using structured programming and data structuring. A derivative known as Object Pascal designed for object-oriented programming was developed in 1985. ==History== Pascal, named in honor of the French mathematician and philosopher Blaise Pascal, was developed by Niklaus Wirth. Before his work on Pascal, Wirth had developed Euler and ALGOL W and later went on to develop the Pascal-like languages Modula-2 and Oberon. Initially, Pascal was largely, but not exclusively, intended to teach students structured programming.〔(Essential Pascal ) by Marco Cantù〕 A generation of students used Pascal as an introductory language in undergraduate courses. Variants of Pascal have also frequently been used for everything from research projects to PC games and embedded systems. Newer Pascal compilers exist which are widely used.〔(tiobe.com ), Programming Community Index for January 2011.〕 Pascal was the primary high-level language used for development in the Apple Lisa, and in the early years of the Macintosh. Parts of the original Macintosh operating system were hand-translated into Motorola 68000 assembly language from the Pascal sources.〔Hertzfeld, Andy. "(Hungarian folklore.org ): Macintosh Stories. Retrieved 2012-03-06.〕 The typesetting system TeX by Donald E. Knuth was written in WEB, the original literate programming system, based on DEC PDP-10 Pascal, while applications like Total Commander, Skype and Macromedia Captivate were written in Delphi (Object Pascal). Object Pascal (Embarcadero Delphi) is still used for developing Windows applications but also has the ability to cross compile the same code to Mac, iOS and Android. Another cross-platform version called Free Pascal, with the Lazarus IDE, is popular with Linux users since it also offers write once, compile anywhere development. CodeTyphon is a Lazarus distribution with more preinstalled packages and cross compilers. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pascal (programming language)」の詳細全文を読む スポンサード リンク
