That book was great. I made the mistake (perhaps) of using it to try to learn assembly language right after learning BASIC (Advanced BASIC that comes with MS-DOS/PC-DOS) and before learning Pascal or C. It had a program you were supposed to type in (a hex editor), and I was able to get it to work, but I was not able to get programs of my own design to work except very tiny programs or to modify existing executables using DEBUG. (Then again, shortly after, I could not get C programs of my own design to work very often either. I forget how hard C is to a beginner sometimes.) Then again, eventually I was able to throw together a decent hex editor, in C this time, in an afternoon, and I am certain it was from internalizing what I had learned from that assembly book, and when I started including assembly language graphics routines in my C programs, I'm sure that helped as well. When everything moved to 32-bit protected-mode code I was kind of lost again though. That book is 16-bit real mode.
