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.

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.

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.

The book presents both a tutorial and a reference on programming the IBM PC microcomputers in the assembler language and on related hardware and architectural issues of the IBM personal computers or IBM-compatible ones. Essentially no previous knowledge of any programming language or about PC architecture is required for this text. The author goes through all the relevant material, starting from the very basics and ending with more advanced topics concerning assembler language programming and the interaction with operating system, in sufficient extent and clarity of exposition.
