At the heart of POWR-DOS is an invisible machine-language program that enhances TEXT and BASIC. Once these enhancements are in place, you have complete access to the PDD using BASIC commands. Surrounding this invisible program are a number of BASIC programs. You can load these independently of each other, and use them only when needed. Chapters One through Six in this manual Explain how to use the POWR-DOS utilities. Each of these chapters consists of three sections: * BASIC Procedures for using the utility. These instructions are as brief as we could make them; they will help you get "up and running" as quickly as possible. * Notes and Options to the basic procedures. Here you will find more detail and interesting options once you have mastered the basics. You may skip this section on first reading, but you will probably want to come back to it later. * Errors and Recovery from the more common problems. Turn to this section when something does not go as expected. We only covered the most common errors; to cover everything would have taken volumes.
