For a discussion of APL, the philosophy behind it, and the role of mathematical notation in programming, I recommend the 1979 Turing Award lecture, by Kenneth Iverson, the designer of APL, entitled "Notation as a Tool of Thought". It is published in the book _ACM Turing Award Lectures: The First Twenty Years_ (1987 - ACM Press).
