Explores the Micro's Internal Organization, Instruction Set, Programming Techniques, Input/Output & Register Management

This hands-on guide helps develop programming skills on the 8086-based microcomputers. Introduces readers to assembly language programming through a comprehensive set of input/output procedures and useful subroutines for the most popular 8086-based operating systems. Covering fundamental data types, segmentation, assembler operation and modular programming, these routines let users apply assembly language ``shortcuts'' and programming techniques to specific applications. Offers a brief outline of the design of the l6-bit microprocessor and the architecture of the 8086 including the 80286 family of chips, presents the essentials on binary and hexadecimal numbers and shows how to write and execute a program. The complete instruction set is presented in the last nine chapters.

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.
