Essential PC-DOSThis authoritative work presents the practical concepts of the IBM-PC disk operating system, along with detailed information on using, moving and safeguarding the files. It begins with a description of the components of the IBM-PC, the operating system, talking to PC-DOS, files and file names. Part II explains various PC-DOS commands--starting, using and moving files, safeguarding files, advanced commands, printer and screen controls, and using the hard disk. Part III deals with the application program EDLIN provided with PC-DOS, as well as PC-DOS batch files and how to use them to tune your system to your own specifications. The appendixes provide a brief history of microcomputing, and cover computer languages and numbers, output and communications devices such as Cathode Ray Tube, television screen and the printer, and MS-DOS equivalents.
