(A Programming Language) A high-level mathematical programming language noted for its brevity and matrix generation capabilities. Developed by Kenneth Iverson in the mid-1960s, it runs on micros to mainframes and is often used to develop mathematical models. It is primarily an interpreted language, but compilers are available.|
APL uses unique character symbols and, before today's graphical interfaces, required special software or ROM chips to enable the computer to display and print them. APL is popular in Europe.
