APL (named after the book A Programming Language) [3] is a programming language developed in the 1960s by Kenneth E. Iverson. Its central datatype is the multidimensional array. It uses a large range of special graphic symbols [4] to represent most functions and operators, leading to very concise code.

APL 是 A Programming Language 或 Array Processing Language 的缩写。 肯尼斯·艾佛森 在1962年设计这个语言时他正在 哈佛大学 工作，1979年他因对 数学表达式 和 编程语言 理论的贡献而得到 图灵奖。 在过去数十年的使用历史中，APL 从它的原始版本开始不断改变和发展，今天的版本与1963年发表时的版本已经非常不一样了。 但它始终是一种解释执行的计算机语言。 现代的 APL 版本支持其初始版本不支持的结构和模式编程。 APL 至今依然使用一种非标准化的字母 …

The Johns Hopkins University Applied Physics Laboratory (or simply Applied Physics Laboratory, or APL) is a not-for-profit university-affiliated research center (UARC) in Howard County, Maryland. It is affiliated with Johns Hopkins University and employs 8,700 people as of 2024. [2] APL is the nation's largest UARC. [3]

Without proper rendering support, you may see question marks, boxes, or other symbols instead of APL symbols. The programming language APL is distinctive in being symbolic rather than lexical: its primitives are denoted by symbols, not words. These symbols were originally devised as a mathematical notation to describe algorithms. [1] .

Welcome to APL Wiki, 452 articles about APL that anyone can edit. See the navigational overview of content. APL is an array-oriented programming language. Its natural, concise syntax lets you develop shorter programs while thinking more about the problem you're trying to solve than how to express it to a computer.

APL's syntax refers to the way programs are written—the arrangement of functions and arrays, along with other values, keywords, and punctuation—in contrast to its semantics, that is, the meaning of the actual operations performed.
