Designed for use on advanced architecture courses, this is a practical reference text for anyone interested in assembly language programming and, more specifically, the configuration and programming of the Intel-based personal computer. Coverage includes both a concise presentation of assembly language programming for the beginner and a complete study of advanced topics. A disk containing many of the more advanced versions of the example programs is included with the text. This disk contains the unassembled source files of many of the example programs. It also contains a macro include file that eases the task of assembly language programming by providing macros that perform most of the I/O tasks associated with assembly language programming.
