There are many books and resources about Pascal<\/a> out there, but too many of them talk about the old Pascal, without classes, units or generics.<\/p>\n

So I wrote this quick introduction to what I call modern Object Pascal. Most of the programmers using it don\u2019t really call it “modern Object Pascal<\/a>“, we just call it “our Pascal<\/a>“. But when introducing the language, I feel it\u2019s important to emphasize that it\u2019s a modern, object-oriented language. It evolved a lot since the old (Turbo) Pascal that many people learned in schools long time ago. Feature-wise, it\u2019s quite similar to C+ +<\/a> or Java<\/a> or C#.<\/p>\n

\u2022 It has all the modern features you expect \u2014 classes, units, interfaces, generics\u2026<\/p>\n

\u2022 It\u2019s compiled to a fast, native code,<\/p>\n

\u2022 It\u2019s very type safe,<\/p>\n

\u2022 High-level but can also be low-level if you need it to be.<\/p>\n

It also has excellent, portable and open-source compiler called the Free Pascal Compiler, http:\/\/freepascal.org\/ . And an accompanying IDE (editor, debugger, a library of visual components, form designer) called Lazarus http:\/\/lazarus.freepascal.org\/ . Myself, I\u2019m the creator of Castle Game Engine, https:\/\/castle-engine.io\/ , which is an open-source 3D and 2D game engine using modern Pascal to create games on many platforms (Windows, Linux, macOS, Android, iOS, Nintendo Switch; also WebGL is coming).<\/p>\n

This introduction is mostly directed at programmers who already have experience in other languages. We will not cover here the meanings of some universal concepts, like “what is a class”, we\u2019ll only show how to do them in Pascal.<\/p>\n","protected":false},"excerpt":{"rendered":"
