A++ stands for 'abstraction plus reference plus synthesis' which is used as a name for the minimalistic programming language that is built on ARS.

ARS is an abstraction from the Lambda Calculus, taking its three basic operations, and giving them a more general meaning, thus providing a foundation for the three major programming paradigms: functional programming, object oriented programing and imperative programming.

The language is introduced on the Web Site:http://www.aplusplus.net
and is fully covered in the book A++ The Smallest Programming Language in the World
published in 2004 with the following ISBN:
3-87820-116-8.

A++ is an educational programming language offering an ideal environment for basic training in programming with its interpreter available in Perl, C, Scheme, Java, C++ and Python, enforcing a rigorous confrontation with the essentials of programming languages.

A++ has been developed in 2002 with the purpose to serve as a learning instrument rather than as a programming language used to solve practical problems.

It is supposed to be an efficient tool to become familiar with the core of programming and with programming patterns that can be applied in other languages needed to face the real world.
