Teaches assembly language programs for the IBM-pc as well as the principles of computer operations. also covers the intel 8088 word processor & use of line editor.

Presents features of Pentium architecture and key instructions. The book trains readers to understand hardware, machine-language code and hexagonal format, writing programs in assembly language, trace element execution, writing macro instructions and linking separately assembled programs into one.

Explains how the computer represents data and introduces the variables, constants, statements, and expressions of assembly language.

Basic features of PC Hardware - Instruction addressing and execution - Examining computer memory and executing instructions - Requirements for coding in assembly language - Assembling, linking, and executing programs - Symbolic instructions and addressing - Program logic and control - Introduction to video and keyboard processing - Disk storage I : organization - Disk storage II : writing and reading files - Disk storage III : INT 21H functions for supporting disks and files - Disk storage IV : INT 13H disk functions - Facilities for printing - Defining and using macros - Linking to subprograms - Program loading and overlays - BIOS data areas, interrupts, and ports - Operators and directives - The PC instruction set.

This unique approach to teaching assembly language takes advantage of the built-in "system" subroutines in the IBM-DOS operating system. No previous experience with assembly language is assumed.
