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.

APL is an array-oriented programming language that will change the way you think about problems and data. With a powerful, concise syntax, it lets you develop shorter programs that enable you to think …

APL is an array language, and one of the oldest programming languages still in use today, next to FORTRAN, Lisp and COBOL. APL uses its own curious-looking symbols, like ⍎⌽⍕⌈* ≡⍬, rather …

While the Basics and Fortrans of the world continue as popular models of what programming languages are, the unconventional APL will persist as a model of how much better programming languages …

GNU APL is made up of more than 100,000 lines of C++ code. In a code of that size, programming mistakes are inevitable.

Unlike many programming languages, APL wasn't designed to match the ways in which a computer works internally. It was intended to help people define procedures for solving problems.

What is APL? APL (named after the book A Programming Language) is an advanced array programming language developed in the 1960s by Dr. Kenneth E. Iverson. Its most powerful attribute …

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 …

What APL is best known for is its use of non-ASCII symbols, including some Greek letters. It is a dynamically typed interactive, array oriented language with a dynamic scope. In APL, all expressions …
