汇编语言是计算机专业的专业基础课，也是电子、通信等相关专业的计算机课程。本书介绍80x86汇编语言程序设计的方法和技术，共分为两个部分：第一部分为基础知识，介绍80x86cpu的编程结构，汇编语言程序的格式和伪指令，80x86cpu的寻址方式和指令系统；第二部分为编程方法，深入讨论分支程序、循环程序、子程序基本程序设计方法，以及以中断为主的i/o程序设计，其中包括宏指令、多模块连接技术、汇编语言与高级语言的混合编程、dos和bios提供的常用中断调用，以及文件系统等内容。-Assembly language is a computer professional basic course, but also the electronics, communications and other related professional computer courses. This book describes 80x86 assembly language programming methods and techniques, is divided into two parts: the first part is the basics, introduction programming structure of 80x86cpu, assembly language program formats and directive, 80x86cpu addressing modes and instruction　The second part is the programming method, in-depth discussion of the branch program, recycling program, subroutine program design methods, and to interrupt the i/o programming, including macro, multi-module connection technology, assembly language and high-level language commonly mixed programming, dos and bios interrupt calls, and file system.
