Book excerpt: Provides comprehensive coverage of all 8086 (8088) and 8087 instructions, assembler directives, and the most important MS-DOS and ROM BIOS functions. Progressing from simple to complex tasks, this text allows students to write complete programs, prepare them for execution, run them, and use most of the facilities of the whole computer system. Most sample programs are preceded by PASCAL and BASIC programs meeting the same specifications. Includes detailed discussions and examples of CP/M and XENIX style file handling, thorough coverage of graphics, plus a thorough introduction to the 8087 coprocessor. Also included are 180 exercises, annotated tables of 8086 and 8087 instructions, chapter summaries and lists of key words, and numerous line drawings. All 60 programs are accompanied by diskettes, eliminating the need for lengthy typing.
