Abstract :
Since the release in August 1968 of the APL/ 360 interpretive time-sharing system, the algebraic language called APL has gained many enthusiastic users. Users of APL consist of those who use it as a desk calculator, as a tool for programming and calculating complex mathematical functions, to define and simulate computer systems, to teach elementary and secondary school children, to teach engineering, to edit technical papers, and to carry out many other tasks with varying degrees of complexity. A novice in the use of the APL will find the book very helpful as a guide to concepts and use of an APL terminal system for solving simple and complex problems.
