    New to mainframes
  

*by J***N on Reviewed in the United States on June 6, 2010*

Start with this book if you need to learn about mainframes!  This was one of the best written technical books I have ever read. I just started a job that uses mainframes and had no idea what a mainframe was or where to start learning the basics. This book answered so many question and has helped me interface with my team members.  It covers so many of the things you need to know and be able to talk to experienced mainframe programmers. operators, etc.  Best of all this book was so easy to read. I would recommend this book to anyone new to mainframes or just interested in learning about mainframes.

    Well written but a bit too brief
  

*by A***K on Reviewed in the United States on February 28, 2020*

In the description they clearly stated that it is a brief high-level introduction. As such, it is very good. But it is, indeed, a high-level introduction. I would prefer it to go a bit deeper but it does what it claims, so honest 5 stars there.Using the info from the book, already knowing what to look for, I was then able to scour the wikipedia for more details on various topics. So all in all, for me personally it was 20 bucks well spent.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Mainframe for Dummies
  

*by D***N on Reviewed in the United States on March 1, 2010*

Of course they would never have titled it "The Mainframe for Dummies", but that's really what it is, and it is a genuinely needed book. Too many books about the mainframe assume the reader already understands what is meant by terms like JCL or VSAM. That simply isn't the case; most people in technology careers have not been exposed to mainframe terms. Then, when they finally are, they are confronted by an avalanche of information. This book certainly does not go into depth, but it acts as a greatly needed first step into the world of big iron. You can read this book in a day, and once you are done you will understand what it means when someone fires up a 3270 session to check the abends on a CICS transaction. If you are ever faced with mainframes or mainframe programmers and you have no idea what either of them do then this book will serve as an excellent introduction.
