MVS Assembler Language

Can't really find anything more to ask for in a book on Assembler development. Clear explanations.

The purchase was just what I hoped for and it was in the condition as described by the seller. Thanks!.

I wanted to learn MVS assembler , and this book helped me to achieve it , use it as the first book , the one's who introduce you slowly but surely to the MVS assembler world , then if you want to discover system programming stuffs search for the book written by Carmine Cannatello (Advanced ..), unfortunately those books are rare these days.
