From the Preface:
In "The Complete Rainbow Guide to OS-9", we explained how OS-9 works-inside, as well as on the command line. We gave you the foundation and structure needed to build a stable of OS-9 programming skills. We hope you will continue to learn from it as you use this book to move up to the fascinating windowing environment made possible by Tandy's Color Computer 3 and OS-9 Level II.
