An Experiment in a User-Oriented Computer System A version of a software-hardware system for the purpose of facilitating the programming and analysis of well-formulated problems is described. A modified Flexowriter is used to generate computer-acceptable input when equations or computable requests are typed in much the same manner as they would appear in conventional mathematical texts. The typing and language rules are quite flexible and unrestrictive. While the compiler part is efficient, the system as a whole has much broader aspects as a tool for the study of problem solving and self-teaching systems. CACM May, 1964 Klerer, M. May, J.
