This booklet describes the Registration Management System, an online computer system developed as one part of a family of educational management systems. The system promotes the rapid collection and storage of course enrollment data and student demographic data through the use of remote timesharing computer terminals located at individual schools. The booklet is organized into two sections--a brief general description and a user's guide, which provides a detailed explanation of how to use the system. Numerous examples of various program functions and output are presented throughout the user's guide. (Author/JG)
