This book gives first-class explanations of the architectural knowledge required for assembler programming, supplying all you need to write easy material for the IBM PC.

The author used PCDOS as the Operating System for this book but states that CP/M has an almost identical assembler instruction set. He points out that the suppliers are continually upgrading their systems, so the final authority rests with the manuals.

Should you feel capable of teaching yourself how to program in assembler then Abel's book is as good as any other.

If you are unsure as to whether or not you would like to use a low-level language then look elsewhere for advice, or for a cheaper guide.
