User's Guide IBM Personal Computer and Compatible Version Preface Congratulations on your decision to purchase UniForm. It will open new avenues of communication between your Computer and many others, giving you the ability to exchange diskettes füll of Information with people using other types of Computers. We think you'll agree that UniForm is one of the best additions you've ever rnade to your Computer System. UniForm allows you to redefine the Operating forrnat of one of your floppy disk drives. You manipulate the data on the diskette with the tools you normally use: word processors, file transfer Utilities, or other pro- grams. UniForm is Invisible to you when it is in use. This manual assumes that you have a basic working knowledge of your Computer System and the programs you will be using. If you have not yet learned to use COPY (for copying files between diskettes) and CHKDSK (for checking how much room is left on a diskette), you should read your DOS manuals and use a practice diskette to learn the basics of them. Once you know the basics, you can move on to UniForm. This User's guide will provide practical examples to Supplement the self-prompting menus of UniForm. If you want to know more about what First Edition (October 1984) UniForm does, read the introduction, which follows. When you're ready Copyright © 1984 by Micro Solutions, Inc. to start using UniForm, take just a moment to read about the conven- tions; then you'll quickly be on your way. Micro Solutions, Inc. -
