The APL\360 terminal system

Abstract

APL\360 is an experimental interactive system, programmed for IBM System/360 computers, which uses typewriter terminals connected to the central machine by telephone lines for both input and output. The basis of the system is APL [1-4], a truly machine-free programming language which leans heavily on mathematical notions, but does not slavishly follow classical mathematical notation. Correspondingly, the running system, which is completely interpretive, makes no significant concessions to implementation problems.
