A+ (programming language)

For information on the A+ computer certification program, see CompTIA. A+ is an array programming language, a dialect of APL with aggressive extensions.  Arthur Whitney developed the "A" portion of A+, while other developers at Morgan Stanley extended it, adding a graphical user interface and other language features. A+ was designed for numerically intensive applications, especially those found in financial applications. A+ runs on many Unix variants, including Linux. A+ is a high-level, interactive, interpreted language.

APL (A Programming Language) is an array programming language based on a notation invented in 1957 by Kenneth E. Iverson while at Harvard University. It originated as an attempt to provide consistent notation for the teaching and analysis of topics related to the application of computers. Iverson published his notation in 1962 in a book titled A Programming Language, and APL got its name from the title of this book. In 1964, a subset of the notation was implemented as a programming language. Iverson received the Turing Award in 1979 for his work.
