DIGITAL RESEARCH(r) CP/M Plus TM (CP/M Version 3) Operating ...

Section 5 rovides detailed information on each CP/M 3 utility program, arranged
alphabetically for easy reference. Many of these are programming utilities that you will not use
until you start writing your own CP/M 3 programs. Section 6 tells you how to use ED, the
CP/M 3 file editor. With ED, you can create and edit program source codes, text, and data files.
Appendix A lists the messages CP/M 3 displays when it encounters special condi- tions,
and describes corrective action where necessary. Appendix B provides an ASCII to hexadecimal
conversion table. Appendix C lists the filetypes associated with CP/M 3. Appendix D lists and
defines the CP/M 3 control characters. Appendix E provides a glossary of commonly used
computer terms.
If you are new to computers, you might find some of the topics, such as the programming
utilities, difficult to understand at first. Learning to use your computer is a challenge, and we
hope you will find it fun. This book proceeds step-by-step so that you can quickly proceed from
opening your new system disk package to mastering CP/M 3's powerful facilities.
