To the eternal memory of Kathleen M. Duntemann, Godmother 1920–1999 who gave me books when all I could do was put teeth marks on them. There are no words for how much I owe you!

Acknowledgments

First of all, to the authors of the software that I am honored to provide by their permission on this book''s CD-ROM:

Robert Anderton, author of NASM-IDE: www.inglenook.co.uk/nasmide/

Anthony Williams, author of ALINK: http://alink.home.dhs.org/

And, of course, the NASM team: Julian "Jules" Hall, Simon Tatham, H. Peter Anvin, John Fine, Kendall Bennet, Gary Clark, and Andrew Crabtree: www.web-sites.co.uk/nasm/

Because of their generosity, there is "nothing else to buy." Everything you need to program in assembly is right here on the CD-ROM for this book.

Abundant thanks also go to Bill Schindler, for teaching me the ways of the C library, and Michael Abrash, who has always has been the rock upon whom my knowledge of assembly language itself has been anchored.

Finally, to Carol, as always, for the sacramental friendship that has challenged me, shaped me, and redeemed me every day of our 30 years together and 23 years as spouses.
