APL (A Programming Language) is an array oriented, functional, interactive programming language created and developed by Kenneth Iverson in the 1960's. It uses a large range of special graphic symbols to represent functions and operators, giving very concise code.^{[1]} It influenced many other programming languages such as J and Mathematica.
