Welcome to APL Wiki,

447 articles about APL that anyone can edit

APL is an array-oriented programming language. Its powerful, concise syntax lets you develop shorter programs that enable you to think more about the problem you're trying to solve than how to express it to a computer.

Running APL

Traditionally a commercial language, there are now quite a few implementations available to download for free without feature limitations, and several of these can be tried online without installing anything.

Examples

APL's terseness means that substantial programs are expressible in a small space, relative to many other programming languages. Here are some examples:
