A+ is a high-level, interactive, interpreted array programming language designed for numerically intensive applications, especially those found in financial applications. In 1985, Arthur Whitney created the A programming language to replace APL. Other developers at Morgan Stanley extended it to A+, adding a graphical user interface (GUI) and other language features. The GUI A+ was released in 1988. Arthur Whitney went on to create a proprietary array language named K. Like J, K omits the APL character set. It lacks some of the perceived complexities of A+, such as the existence of statements and two different modes of syntax. More information...
