APL Wiki main page
This wiki is all about APL, an array-oriented programming language that will change the way you think about problems and data. With a powerful, concise syntax, APL lets you develop shorter programs that enable you to think more about the problem you're trying to solve rather than how to express it to a computer. You can try APL now online or download it for free.

Who uses APL?
There are many case studies of both hobby and real-world APL applications. Many of these are still active today.
There is an active APL chat room on Stack Exchange.
There are active user groups all around the globe, many of these hold regular in-person meet-ups.
Examples
APL's terseness lends to substantial programs begin expressable in a small space, relative to many other programming languages. Here are some examples:
| Split text by delimiter | ','(≠⊆⊢)'comma,delimited,text' |
| Conway's "Game of Life" | {↑1 ⍵∨.∧3 4=+/,¯1 0 1∘.⊖¯1 0 1∘.⌽⊂⍵}
