Recent advances in the design of computer systems and programming languages have created a need for a state-of-the-art book on programming and computer techniques. This book has two objectives. The first is to present the APL language and terminal system. APL combines the power and relevance of Iverson's programming language* with the convenience of time sharing to provide an effective system for solving small intermediate, and large-scale problems. The second objective is to provide and introduction to computer techniques for scientists, engineers, business analysts, and managers. One of the major difficulties, initially, is a conceptual one of gaining familiarity with basic computing concepts and recognizing possible applications. A significant portion of this book is directed toward this end and toward the presentation of general information on computer systems and devices and on programming systems and languages.
