It features modules with namespace control, including parallel tasking modules with semaphores, objects, dynamic arrays of any dimensions that are allocated at runtime, overloads, overrides, and many other extensions.

IP Pascal Implements the language “Pascaline” (named after Pascal’s calculator), which is a highly extended Pascal compatible with original Pascal according to ISO 7185.Currently, older versions of Turbo Pascal (up to 5.5) are available for free download from Borland’s site. Slow floppy disk drives were common for programmers at the time, further magnifying Turbo Pascal’s speed advantage. Turbo Pascal was compactly written and could compile, run, and debug all from memory without accessing disk. Turbo Pascal was the dominant Pascal compiler for PCs during the 80s and early 90s, popular both because of its powerful extensions and extremely short compilation times.P5 compiler, is an ISO 7185 (full Pascal) adaption of P4.P4 compiler, the basis for many subsequent Pascal-implemented-in-Pascal compilers, including the UCSD p-System.Current version runs a dialect of Object Pascal largely compatible with Delphi, but also supports language constructs elements introduced in Prism. DWScript aka DelphiWebScript, is an interpreter created by Matthias Ackermann and Hannes Hernler in 2000.

Modern Pascal is available for numerous platforms including Linux, FreeBSD, Mac OS X, Microsoft Windows, 32bit and 64bit CPUs, along with ARM for the Raspberry Pi. Available as a command line tool, Apache Module (like PHP), Middleware solution like ColdFusion, or Stand-Alone multi-threaded server like Node.js. Modern Pascal is a robust Turbo Pascal, Delphi and Free Pascal interpreter and p-code compiler.

Free Pascal Free 32/64/16-bit multi-platform Pascal and Object Pascal compiler.

CDC 6000 Pascal compiler The source code for the first (CDC 6000) Pascal compiler.

Extensions to the Pascal concepts led to the Pascal-like languages Modula-2 and Oberon. A derivative known as Object Pascal designed for object-oriented programming was developed in 1985 this was used by Apple Computer and Borland in the late 1980s and later developed into Delphi on the Microsoft Windows platform. Wirth had already developed several improvements to this language as part of the ALGOL X proposals, but these were not accepted and Pascal was developed separately and released in 1970. Pascal was developed on the pattern of the ALGOL 60 language. It is named in honor of the French mathematician, philosopher and physicist Blaise Pascal. Pascal is an imperative and procedural programming language, which Niklaus Wirth designed in 1968–69 and published in 1970, as a small, efficient language intended to encourage good programming practices using structured programming and data structuring.
