`!Object Pascal`! is an extension to the programming language `F33f`_`[Pascal`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Pascal_(programming_language)]`_`f that provides `F33f`_`[object-oriented programming`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Object-oriented_programming]`_`f (OOP) features such as `F33f`_`[classes`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Class_(computer_programming)]`_`f and `F33f`_`[methods`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Method_(computer_programming)]`_`f.

The language was originally developed by `F33f`_`[Apple Computer`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Apple_Inc.]`_`f as `*`F33f`_`[Clascal`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Clascal]`_`f`* for the `F33f`_`[Lisa`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Apple_Lisa]`_`f Workshop development system. As Lisa gave way to `F33f`_`[Macintosh`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Mac_(computer)]`_`f, Apple collaborated with `F33f`_`[Niklaus Wirth`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Niklaus_Wirth]`_`f, the author of Pascal, to develop an officially standardized version of Clascal. This was renamed Object Pascal. Through the mid-1980s, Object Pascal was the main programming language for early versions of the `F33f`_`[MacApp`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=MacApp]`_`f `F33f`_`[application framework`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Application_framework]`_`f. The language lost its place as the main development language on the Mac in 1991 with the release of the `F33f`_`[C++`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=C++]`_`f-based MacApp 3.0. Official support ended in 1996.

`F33f`_`[Symantec`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Gen_Digital]`_`f also developed a `F33f`_`[compiler`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Compiler]`_`f for Object Pascal for their Think Pascal product, which could compile programs much faster than Apple's own `F33f`_`[Macintosh Programmer's Workshop`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Macintosh_Programmer's_Workshop]`_`f (MPW). Symantec then developed the Think Class Library (TCL), based on MacApp concepts, which could be called from both Object Pascal and `F33f`_`[THINK C`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=THINK_C]`_`f. The Think suite largely displaced MPW as the main development platform on the Mac in the late 1980s.

Symantec ported Object Pascal to the PC, and developed a similar object framework on that platform. In contrast to TCL, which eventually migrated to C++, the PC `F33f`_`[libraries`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Library_(computing)]`_`f remained mainly based on Pascal.

`F33f`_`[Borland`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Borland]`_`f added support for object-oriented programming to `F33f`_`[Turbo Pascal`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Turbo_Pascal]`_`f 5.5, which would eventually become the basis for the Object Pascal dialect used in `F33f`_`[Delphi`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Delphi_(software)]`_`f created by `F33f`_`[Anders Hejlsberg`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Anders_Hejlsberg]`_`f. Delphi remained mainstream for business applications on the PC into the early 2000s, and was partly displaced in the 2000s with the introduction of the `F33f`_`[.NET Framework`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=.NET_Framework]`_`f which included Hejlsberg's `F33f`_`[C#`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=C_Sharp_(programming_language)]`_`f.

>>History

>>>Apple Pascal

Pascal became a major language in the programming world in the 1970s, with high-quality implementations on most `F33f`_`[minicomputer`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Minicomputer]`_`f platforms and `F33f`_`[microcomputers`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Microcomputer]`_`f. Among the latter was the `F33f`_`[UCSD Pascal`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=UCSD_Pascal]`_`f system, which compiled to an intermediate `*p-System`* code format that could then run on multiple platforms. Apple licensed UCSD and used it as the basis for their `F33f`_`[Apple Pascal`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Apple_Pascal]`_`f system for the `F33f`_`[Apple II`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Apple_II]`_`f and `F33f`_`[Apple III`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Apple_III]`_`f.

Pascal became one of the major languages in the company in this period. With the start of the `F33f`_`[Apple Lisa`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Apple_Lisa]`_`f project, Pascal was selected as the main programming language of the platform, although this time as a `*compiler`* in contrast to the p-System `*interpreter`*.

>>>Clascal and Apple's early Object Pascal

Object Pascal is an extension of the Pascal language that was developed at `F33f`_`[Apple Computer`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Apple_Inc.]`_`f by a team led by `F33f`_`[Larry Tesler`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Larry_Tesler]`_`f in consultation with `F33f`_`[Niklaus Wirth`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Niklaus_Wirth]`_`f, the inventor of Pascal.`:cite-ref-2[`F5bf`_`[2`#cite-note-2]`_`f]`:cite-ref-3[`F5bf`_`[3`#cite-note-3]`_`f] It is descended from an earlier object-oriented version of Pascal named `F33f`_`[Clascal`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Clascal]`_`f, which was available on the `F33f`_`[Lisa`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Apple_Lisa]`_`f computer.

Object Pascal was needed to support `F33f`_`[MacApp`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=MacApp]`_`f, an expandable Macintosh application framework that would now be termed a `F33f`_`[class library`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Class_library]`_`f. Object Pascal extensions, and MacApp, were developed by Barry Haynes, Ken Doyle, and Larry Rosenstein, and were tested by Dan Allen. Larry Tesler oversaw the project, which began very early in 1985 and became a product in 1986.

An Object Pascal extension was also implemented in the Think Pascal `F33f`_`[integrated development environment`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Integrated_development_environment]`_`f (IDE). The IDE includes the compiler and an editor with `F33f`_`[syntax highlighting`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Syntax_highlighting]`_`f and checking, a powerful `F33f`_`[debugger`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Debugger]`_`f, and a class library.`:cite-ref-4[`F5bf`_`[4`#cite-note-4]`_`f] Many developers preferred Think Pascal over Apple's implementation of Object Pascal because Think Pascal offered a much faster compile–`F33f`_`[link`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Linker_(computing)]`_`f–debug cycle, and tight integration of its tools. The last official release of Think Pascal was 4.01, in 1992. `F33f`_`[Symantec`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=NortonLifeLock]`_`f later released an unofficial version 4.5d4 at no charge.

Apple dropped support for Object Pascal when they moved from `F33f`_`[Motorola 68000 series`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Motorola_68000_series]`_`f chips to IBM's `F33f`_`[PowerPC`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=PowerPC]`_`f architecture in 1994. MacApp 3.0, had already been rewritten in `F33f`_`[C++`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=C++]`_`f and ported to this platform.

`F33f`_`[Metrowerks`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Metrowerks]`_`f bundled an Object Pascal compiler with `F33f`_`[CodeWarrior`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=CodeWarrior]`_`f that targeted both `F33f`_`[68k`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Motorola_68000_series]`_`f and `F33f`_`[PowerPC`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=PowerPC]`_`f, both in their IDE and as MPW tools. Macintosh developers using Object Pascal had a path to port to the `F33f`_`[PowerPC`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=PowerPC]`_`f, even after both Apple and Symantec dropped support. `F33f`_`[MacApp`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=MacApp]`_`f 2.0, written in Object Pascal, was ported to the PowerPC using `F33f`_`[CodeWarrior`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=CodeWarrior]`_`f.`:cite-ref-mt1995-11-5-0[`F5bf`_`[5`#cite-note-mt1995-11-5]`_`f]`:cite-ref-mt1996-02-6-0[`F5bf`_`[6`#cite-note-mt1996-02-6]`_`f]

>>Borland, Inprise, CodeGear, and Embarcadero years

In 1986, `F33f`_`[Borland`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Borland]`_`f introduced similar extensions, also named Object Pascal, to the `F33f`_`[Turbo Pascal`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Turbo_Pascal]`_`f product for the Macintosh, and in 1989 for Turbo Pascal 5.5 for DOS. When Borland refocused from `F33f`_`[DOS`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=DOS]`_`f to `F33f`_`[Windows`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Microsoft_Windows]`_`f in 1994, they created a successor to Turbo Pascal, named `F33f`_`[Delphi`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Delphi_(software)]`_`f, and introduced a new set of extensions to create what is now known as the Delphi language.

The development of Delphi started in 1993 and Delphi 1.0 was officially released in the United States on 14 February 1995. While code using the Turbo Pascal object model could still be compiled, Delphi featured a new syntax using the keyword `B100`F9d9class`f`b in preference to `B100`F9d9object`f`b, the Create constructor and a virtual Destroy destructor (and negating having to call the `B100`F9d9New`f`b and `B100`F9d9Dispose`f`b procedures), properties, method pointers, and some other things. These were inspired by the `F33f`_`[ISO`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=International_Organization_for_Standardization]`_`f working `F33f`_`[draft`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Draft_document]`_`f for object-oriented extensions, but many of the differences from Turbo Pascal's dialect (such as the draft's requirement that all methods be `F33f`_`[virtual`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Virtual_function]`_`f) were ignored.

The Delphi language has continued to evolve over the years to support constructs such as `F33f`_`[dynamic arrays`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Dynamic_array]`_`f, `F33f`_`[generics`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Generic_programming]`_`f and `F33f`_`[anonymous methods`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Anonymous_function]`_`f. The old object syntax introduced by Apple ("Old-Style Object Types") is still supported.`:cite-ref-7[`F5bf`_`[7`#cite-note-7]`_`f]

Smart Pascal integrates tightly with established technologies such as `F33f`_`[node.js`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Node.js]`_`f, Embarcadero DataSnap, and Remobjects SDK to produce high-performance `F33f`_`[client–server model`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Client–server_model]`_`f 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 `B100`F9d9asm`f`b 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 `F33f`_`[virtual method table`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Virtual_method_table]`_`f and many other advanced constructs which are not a part of JavaScript by default.

>>Compilers

Object Pascal `F33f`_`[compilers`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Compiler]`_`f are available for a wide range of `F33f`_`[operating systems`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Operating_system]`_`f and architectures.

• `F33f`_`[Delphi`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Delphi_(software)]`_`f is probably the best known compiler. It is the successor of the highly successful Borland Pascal and `F33f`_`[Turbo Pascal`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Turbo_Pascal]`_`f product line. It targets `F33f`_`[Windows 9x`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Windows_9x]`_`f (Delphi 2007 and older), the `F33f`_`[Windows NT`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Windows_NT]`_`f family, `F33f`_`[.NET Framework`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=.NET_Framework]`_`f (Delphi 8, 2005, 2007), `F33f`_`[macOS`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=MacOS]`_`f (Delphi XE2 and later), `F33f`_`[iOS`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=IOS]`_`f (Delphi XE2 and later, generating native binaries in XE4 and later), `F33f`_`[Android`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Android_(operating_system)]`_`f (Delphi XE5 and later, generating native binaries in XE5 and later). Support for .NET finally became a separate product known as Oxygene (see below).
• `F33f`_`[Free Pascal`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Free_Pascal]`_`f Compiler (FPC) is an open-source Object Pascal compiler that supports many Pascal dialects, including `F33f`_`[Turbo Pascal`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Turbo_Pascal]`_`f 7, Delphi, and others. Currently, FPC can generate code for `F33f`_`[IA-32`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=IA-32]`_`f, `F33f`_`[x86-64`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=X86-64]`_`f, `F33f`_`[PowerPC`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=PowerPC]`_`f, `F33f`_`[SPARC`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=SPARC]`_`f, and `F33f`_`[ARM`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=ARM_architecture]`_`f processors, and for several operating systems, including `F33f`_`[Microsoft Windows`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Microsoft_Windows]`_`f, `F33f`_`[Linux`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Linux]`_`f, `F33f`_`[FreeBSD`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=FreeBSD]`_`f, `F33f`_`[Classic Mac OS`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Classic_Mac_OS]`_`f, and `F33f`_`[macOS`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=MacOS]`_`f (with an `F33f`_`[Xcode`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Xcode]`_`f integration kit). Several separate projects exist to facilitate rapid application development with FPC, the most prominent one being `F33f`_`[Lazarus (IDE)`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Lazarus_(IDE)]`_`f.
• `F33f`_`[GNU Pascal`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=GNU_Pascal]`_`f (a separately distributed part of the `F33f`_`[GNU Compiler Collection`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=GNU_Compiler_Collection]`_`f), while not formally aimed at the Delphi dialect of Pascal, does contain a Turbo Pascal compatibility mode, and is very slowly incorporating a few Delphi language features. It is unsuitable for recompiling large bodies of Delphi code directly, but is notable as having prolific support for operating systems and hardware architectures.
• `F33f`_`[Oxygene`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Oxygene_(programming_language)]`_`f (formerly `*Chrome`*) is an Object Pascal compiler from `F33f`_`[RemObjects Software`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=RemObjects_Software]`_`f that integrates into `F33f`_`[Microsoft Visual Studio`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Microsoft_Visual_Studio]`_`f. It is also available as free `F33f`_`[command-line interface`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Command-line_interface]`_`f compiler that runs native on `F33f`_`[CLI`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Common_Language_Infrastructure]`_`f.

>>>Legacy products

• `F33f`_`[Borland Kylix`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Borland_Kylix]`_`f was a `F33f`_`[Linux`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Linux]`_`f variant of Delphi which only targets Intel 32-bit Linux using the `F33f`_`[Qt`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Qt_(software)]`_`f library. It does not work out of the box with most modern Linux distributions.
• `F33f`_`[Virtual Pascal`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Virtual_Pascal]`_`f was a free 32-bit Turbo Pascal and Delphi compatible compiler for mainly `F33f`_`[OS/2`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=OS/2]`_`f and Microsoft Windows. Later, it also received a DOS+ Extender and an experimental Linux cross-compiler. The compiler's development stopped at about the level of Delphi 2. In 2007, its official website ceased to operate, and further development ceased.

>>Interpreters

Pascal Script (formerly `*InnerFuse`*) and DWScript (Delphi Web Script) are open-source Object Pascal `F33f`_`[interpreters`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Interpreter_(computing)]`_`f 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 `F33f`_`[just-in-time compilation`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Just-in-time_compilation]`_`f (JIT). Modern Pascal provides 3 different interpreters: a `F33f`_`[command-line interface`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Command-line_interface]`_`f (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 `F33f`_`[source code`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Source_code]`_`f.`:cite-ref-16[`F5bf`_`[16`#cite-note-16]`_`f]

>>>Turbo Pascal version

Still supported in Delphi and Free Pascal. FPC also packages its own substitutes for the libraries/units. Delphi does not. The Free Pascal 1.0 series and the FPC textmode IDE are the largest open codebases in this dialect. Free Pascal 2.0 was rewritten in a more Delphi-like dialect, and the textmode IDE and related frameworks (Free Vision) are the only parts in the TP version of Object Pascal.

`B100`F9d9 HelloWorld4: PHelloWorld;`f`b
`B100`F9d9begin`f`b
`B100`F9d9 { This works in a similar way as the code above, note the allocation and de-allocation, though,`f`b
`B100`F9d9 many people get confused. In the past there was a wrong example with wrong comments here... }`f`b
`B100`F9d9`f`b
`B100`F9d9 New(HelloWorld); { one instance }`f`b
`B100`F9d9 HelloWorld4 := HelloWorld; { this is valid - a pointer copy }`f`b

`B100`F9d9 HelloWorld2 := HelloWorld3; { this is valid - a pointer copy }`f`b
`B100`F9d9 Dispose(HelloWorld); { it allocates only two instances }`f`b
`B100`F9d9 Dispose(HelloWorld3); { so it must release only two instances }`f`b

>>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 `F33f`_`[operator overloading`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Operator_overloading]`_`f. Delphi has also introduced many other features since version 7,`:cite-ref-newftrs-17-0[`F5bf`_`[17`#cite-note-newftrs-17]`_`f] 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.
