Abstract
The typesetting of mathematics requires consistency and high quality, which has formerly meant high labor costs and long production schedules. OCR devices, computers, and CRT phototypesetters can provide a low-cost, high-speed alternative to labor-intensive metal typesetting when they are coupled to an adequate software system. The software must encompass the many complex, though precisely definable, rules for math setting and an easy-to-learn, labor-efficient input language. This paper describes such a system, currently in use, including hardware, the logic and assumptions of the software, and examples of the input language.
