A is an APL implementation created in 1985 by Arthur Whitney at Morgan Stanley. It has been replaced by its successor, A+, which featured language enhancements and a graphical user interface and was released in 1988.
A was the first APL to be based on leading axis theory, and included many other new features such as a redesigned defined function syntax with lexical scope and the ability to call functions with function arguments.
