Norton and Socha's authority makes this book a must to every "beginner" assembly programmer. This book presents basic items such as binary numbers, registers & basic arithmetic inside the 8086 family processors into part 1. The contents of the book becomes closely related with DSKPATCH - a real program written in assembly - so the reader has a UNIQUE opportunity to see how real programmers (and here Norton is a PC guru) use step-wise refinements techniques and modular projects in a real world. The 2nd edition is based in MASM 5/5.1, Borland TASM and OPTASM features. Maybe we must wait for MASM 6.1 update... then it'll become a rating 10...
