==Versions==
* [[Borland]] used the name ''Object Pascal'' for the programming language in the first versions, but later renamed it to ''Delphi''. [[Compiler]]s that claim to be compatible with Object Pascal are often trying to be compatible with Delphi [[source code]].{{Citation needed|date=August 2009}} Because Delphi is a [[trademark]], compatible compilers continue using the name ''Object Pascal''.
* [[Embarcadero Technologies]], which purchased Delphi in 2008,<ref>[http://edn.embarcadero.com/article/38132 Community Letter: Embarcadero Technologies agrees to acquire CodeGear from Borland] {{Webarchive|url=https://web.archive.org/web/20180302044728/http://edn.embarcadero.com/article/38132 |date=2018-03-02 }}.

* [[.NET Framework|.NET]] support existed from Delphi 8 through Delphi 2005, 2006, and 2007, which now has been replaced by another language, ''Oxygene'' (see below), which is not fully backward-compatible.
* The [[Oxygene (programming language)|Oxygene]] language developed by [[RemObjects Software]] targets the [[Common Language Infrastructure]], the [[Java (software platform)|Java]] Runtime Environment and [[Apple Inc.|Apple]]'s [[Cocoa (API)|Cocoa]] frameworks for [[iOS]] and [[macOS]].
* The [[open source]] [[Free Pascal]] project allows the language to be compiled for a wide range of [[operating system]]s, including [[Linux]] ([[32-bit]], [[64-bit]]), [[FreeBSD]], [[Classic Mac OS]], [[macOS]], [[Solaris (operating system)|Solaris]], [[Windows API]] (32, 64, [[Windows CE|CE]]), the [[ARM architecture family|ARM]] [[instruction set architecture]] (ISA), and several other hardware architectures.

The language greatly simplifies [[HTML5]] development through object-oriented, and [[rapid application development]] (RAD) methods. Smart Pascal integrates tightly with established technologies such as [[node.js]], Embarcadero [[DataSnap]], and [[Remobjects SDK]] to produce high-performance [[client–server model]] web applications. The language allows easy creation of visual components and reusable libraries. The Smart Pascal dialect stems from the DWScript language, extended to better integrate with the JavaScript environment and libraries, such as <code>asm</code> sections which are plain JavaScript but have access to Pascal symbols, or ''external'' classes which map directly to prototypal JavaScript classes. Smart Pascal introduces true inheritance, classes, partial classes, interfaces, a [[virtual method table]] and many other advanced constructs which are not a part of JavaScript by default.
* The [[Morfik]] Pascal language, developed by Morfik, targets [[Ajax (programming)|Ajax]]-enabled Web applications. The compiler is built into the company's AppsBuilder IDE and allows Object Pascal code to be used in implementing code to execute in a browser or server. It uses the [[Free Pascal]] compiler to generate native binaries from Object Pascal.
* The open source [[GNU Pascal]] compiler is available as a front-end to the [[GNU Compiler Collection]], which implements the [[International Organization for Standardization]] (ISO) 7185 Pascal standard, and most of the ISO 10206 Extended Pascal standard.

==Interpreters==
{{Main|Pascal Script}}
[http://www.remobjects.com/ps Pascal Script] (formerly ''InnerFuse'') and [http://code.google.com/p/dwscript/ DWScript] (Delphi Web Script) are open-source Object Pascal [[Interpreter (computing)|interpreters]] and scripting engines written in Delphi. They support subsets of Object Pascal. DWScript can also compile Object Pascal code into JavaScript code (Smart Pascal), and supports [[just-in-time compilation]] (JIT). Modern Pascal provides 3 different interpreters: a [[command-line interface]] (CLI), Apache Module (Celerity), and CodeRunner (node.js like solution able to handle different scripts per port), besides the ability to compile and protect a script's [[source code]].<ref>{{cite web |url=http://www.modernpascal.com/ |title=Modern Pascal |access-date=2018-10-22 |archive-date=2018-12-11 |archive-url=https://web.archive.org/web/20181211010242/http://modernpascal.com/ |url-status=live }}</ref>

==Development==
Many features have been introduced continuously to Object Pascal with extensions to Delphi and extensions to FreePascal. In reaction to criticism, Free Pascal has adopted generics with the same syntax as Delphi, provided Delphi compatibility mode is selected, and both Delphi (partial) and Free Pascal (more extensive) support [[operator overloading]]. Delphi has also introduced many other features since version 7,<ref name="newftrs">{{cite web|title=New Delphi language features since Delphi 7|publisher=CodeGear|url=http://dn.codegear.com/article/34324|access-date=2008-07-06|archive-date=2008-07-02|archive-url=https://web.archive.org/web/20080702184859/http://dn.codegear.com/article/34324|url-status=live}}</ref> including generics. Whereas FreePascal tries to be compatible to Delphi in Delphi compatibility mode, it also usually introduced many new features to the language that are not always available in Delphi.
