This newly updated and expanded volume contains detailed, thorough and accurate information on MS-DOS written for advanced-level programmers of all environments. Contains an index and appendixes.

The source code of MS-DOS is both secret and copyright-protected. Using the DOS work-alike RxDOS, created to emulate and parallel the commercial system, Dissecting DOS reveals for the first time the code-level operation of DOS. By studying the source code of RxDOS included on disk, readers will be able to understand MS-DOS's inner workings.

A powerful collection of Basic routines to make the intermediate to advanced programmer more productive--faster. Designed to be an erector set for sophisticated applications, the more than 50 reusable programs feature a code-intensive "learn-by-example" approach. The code and descriptions will be particularly useful to programmers who have experience with QuickBasic, Turbo Pascal, or Turbo C.

Explains how to exploit the undocumented capabilities of the MS- DOS operating system when programming commercial software. Updated from the first edition to incorporate not only DOS 5.0 and 6.0, but also the forthcoming DOS 7 and Windows 4. Coverage is also expanded on Windows interfacing, DOS internals, and the role of undocumented interfaces in the software industry. Includes a 3.5" disk; equivalent 5.25" disks are available for $10 more. Annotation copyright by Book News, Inc., Portland, OR
