The Structure And Performance Of Pluto, A Teaching Oriented Pl/I Compiler System
Peter Boulton, D.L. Jeanes · INFOR Information Systems and Operational Research · 1972
PLUTO is a fast in-core batch compiler and highly diagnostic interpreter developed at the University of Toronto for teaching most of the programming techniques possible with PL/I. The compiler uses a concise formal description of the language, and the interpreter provides detailed analysis of run-time errors and their probable causes. The system supports essentially the full PL/I language and provides an economical, effective facility for the teaching and practice of both scientific and data-processing programming.
