But thanks to some Free Pascal enthusiasts, the Lazarus IDE was developed as a powerful RAD environment especially for Free Pascal. It consists of the language, the compiler and a runtime-library - but does not include the RAD-tools which made Delphi famous. Delphi runs only on Windows, but can compile programs for GNU/Linux, MacOS, Windows, iOS and Android, too.įree Pascal in contrast is a free, Open Source implementation of the Object Pascal language. Today there are two major implementations: Delphi, the official Turbo Pascal successor, and Free Pascal.ĭelphi is a commercial Rapid Application Development (RAD) environment, which consists of the Object Pascal language, a powerful and fast compiler, a large runtime-library (RTL) and a designer for crossplatform Graphical User Interfaces (GUI). Over time some object-oriented additions were added to the language by Apple and later by Borland, which has evolved into what we now call Object Pascal. One of the most favourite versions, which made Pascal one of the most well-known and widespread programming languages of the 80s and the early 90s, was Borlands Turbo Pascal 2. But unlike other languages, there were different Pascal dialects and compilers since the very beginning. Pascal was standardized as an ISO standard in the early 90s. As an example, the first version of Photoshop was made with Pascal. With the appearance of the Classic Mac OS, Pascal was the language of choice propagated by Apple for serious application development. It was used as a teaching language as well as a language for business applications. Pascal was initially developed in 1969 by Dr. And although it is in fact one of the older programming languages, it has greatly evolved into a modern, full featured language over the last decades. Pascal is considered by many programmers as an old language from the past.
