This text is a step-by-step, hands-on introduction to the IBM PC, its hardware and operating system, and three primary areas of application: word processing, spreadsheets and data management. Upon completion of the text, the student will have a thorough working knowledge of today's most popular software applications. There are numerous hands-on sections marked by easy-to-find computer icons and easy to use function templates for all software packages. The DOS section features a discussion of sub-directories and the dBase section includes programming in dBase. An extensive appendix covers Lotus 1-2-3, and other appendices contain command summaries of all the software packages. This book should be of interest to degree and diploma students on introductory courses in microcomputer applications using the IBM PC to teach DOS, word processing, spreadsheets and data management.
