• A multi-paradigm language that supports procedural, object-based, object-oriented, and functional programming styles, allowing for flexible educational pathways.

• An ideal tool for teaching, with a clear and logical syntax that is easy for beginners to understand, enabling them to write compact, efficient, and readable code. It is an excellent choice for a wide range of learners, from school students to university-level IT majors.

• A practical everyday tool, perfectly suited for creating console applications and general-purpose programming tasks.

• Distributed under the free LGPLv3 license.

Why PascalABC.NET is Relevant Today

In the 21st century, there is a growing demand for programming languages that allow you to write high-level code in a lightweight, compact, and understandable form. Modern implementations of the Pascal language, such as PascalABC.NET, have a lot to offer here.

Created in 2007 and based on C# and Delphi (Object Pascal) – which hold the 5th and 9th positions, respectively, in the TIOBE 2026 popularity index – PascalABC.NET borrows Python's compact syntax and several constructs while retaining all the advantages of a compiled language (early error checking, high execution speed).

Development & Adoption

PascalABC.NET is a joint international project. Its primary development center in Russia is based at the Institute of Mathematics, Mechanics, and Computer Science of the Southern Federal University.

The platform is widely used in secondary and higher education across Russia and neighboring countries. At the Southern Federal University, it serves as the primary tool for teaching programming fundamentals to IT students and schoolchildren in one of Russia's largest computer schools.
