STUDY HALL is a system for developing and running Computer-Assisted Instruction. It is the least expensive, least complicated, most widely-usable way for you to create and use Computer-Assisted Instruction. STUDY HALL is in the Public Domain, so it is totally free, and there are no licensing fees or copyright legalities to worry about. You only need to learn thirteen control characters to write tutorials. And STUDY HALL should run on any Windows or DOS-compatible system in the world, even minimal ones. STUDY HALL is intended not only for professional educators and course developers, but also for students and hobbyists, such as myself. Even writers of fiction can use STUDY HALL, to create interactive text adventures, where the development of the plot depends on the reader's responses to situations in the story. SOURCE CODE is included, so you can make whatever changes in the program you make desire.
