This book is not a reference book, it is an introductory book. It is therefore not suitable by itself to
learn how to professionally program in x86 assembly language, as some details have been left out to
make the learning process smoother. The point of the book is to help the student understand how
assembly language and computer programming works, not to be a reference to the subject. Reference
information about a particular processor can be obtained by contacting the company which makes it.
