"A+ is an array programming language descendent from the programming language A, which in turn was created to replace APL in 1988. 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."@en . . . . "A+"@en . "4.20-2" . . .
