PEP: An interactive programming system with an Algol‐like programming language
Pieterjan Verhelst, N.F. Verster · Software Practice and Experience · 1984
Abstract PEP (Program Editor and Processor) is an interactive programming system based on an Algol‐like language. It is intended to replace BASIC as a system for interactive program development on small computers (LSI‐11). The language processed by the system allows declaration of variables, constants and procedures; it has structured statements for conditional and repetitive execution of program parts. We describe design and implementation of the system and give our impressions after 1 year of experience with the system.
