Line 9: \|bnf=http://en.wikipedia.org/wiki/ISO_7185}} {{language programming paradigm\|Imperative}} '''Pascal''' is an [[imperative programming\|imperative]] computer programming language, developed in 1970 by [[wp:Niklaus Wirth\|Niklaus Wirth]] as a language particularly suitable for [[wp:structured programming\|structured programming]]. A derivative known as [[:Category:Object Pascal\|Object Pascal]] was designed for [[object-oriented]] programming. Pascal can be used very easily in conjunction with fundamental [[wp:~~Discrete_mathematics~~discrete mathematics\|discrete mathematics]] as sets are built into the language. ~~Actually there~~There are actually several ~~versions~~varieties of Pascal. The most important ones are: * Standard Pascal ([[ISO]] 7185) is the original Pascal standard. However, there are many features missing from that language version, which has led to a wide variety of nonstandard extensions. On the other hand, there are features of Standard Pascal which are seldom implemented by Pascal compilers. A compiler which implements all features of Standard Pascal is [[GNU Pascal]]. * Extended Pascal (ISO 10206) is a later Pascal standard which adds a lot to the original Pascal standard. However, compilers implementing Extended Pascal are even more rare than those implementing Standard Pascal. [[GNU Pascal]] implements most of Extended Pascal as well. * [[Turbo Pascal]] was a very successful Pascal implementation for [[DOS]] and 16 bit [[Windows]] (the latest version was sold under the name "Borland Pascal 7.0") and became the de-facto standard for Pascal on DOS. Even today many Pascal compilers provide compatibility to Turbo Pascal. * [[Object Pascal]] is the Pascal dialect used in [[Delphi]], Borland's successor product to Turbo/Borland Pascal. It extends Pascal with a new object model (in addition to the object model introduced in Turbo Pascal 5.5). This language is also implemented by [[Free Pascal]] and [[Lazarus]]. * [[PascalABC.NET]] PascalABC.NET is the new generation Pascal programming language that combines simplicity of classic Pascal, a great number of modern extensions and broad capabilities of Microsoft .NET Framework. ==~~Citations~~Grammar== The [[wp:ISO 7185\|ISO 7185]] standard for Pascal uses [[wp:Extended Backus–Naur Form\|Extended Backus–Naur Form]]. * [[wp:Pascal (programming language)]]▼ Also [[wp:Van Wijngaarden grammar\|Van Wijngaarden's grammar]] can be used to define [[Pascal]]'s grammar[http://www-users.cs.york.ac.uk/~fisher/software/yoyovwg/exs/pascal.vwg]. ==See also== ▲* [[wp:Pascal (programming language)\|Pascal on Wikipedia]]
