APL, short for A Programming Language, is a language for working with arrays that grew out of a mathematical notation devised by Kenneth Iverson at Harvard in the 1950s for describing computation. A working implementation for IBM computers was developed in the mid-1960s, and the language became widely used for financial and scientific work. It is known for a large set of special symbols, written with a special keyboard, and for very compact programs in which one line can do the work of many in other languages. Iverson received the Turing Award in 1979, and APL influenced later languages and tools such as J, K and MATLAB.
