About the Author
I worked as a programmer for a major insurance company. In 1976 I aided in the introduction of TSO to the staff by testing it, creating a TSO user’s guide, writing Clists, teaching classes in TSO, and making recommendations to the technical support personnel about TSO. I worked on TSO administration, managing user id’s. I automated the administration by writing Clists, TSO native mode commands, utilities, JCL, Assembler language programs, and MVS utilities. At another major insurance company I was introduced to REXX on CMS, and there wrote a user guide for programmers on REXX. When TSO REXX became available in 1988, I began working with it. Several years of that led to the creation of my book “REXX in the TSO Environment.” As a programming contractor, I automated the transfer of an entire data center’s JCL and procedures to another data center, using REXX, IBM utilities, and TSO/ISPF panels. When the publisher decided to drop mainframe books in 1996, the book was no longer published. Shortly after that I created a course for TSO REXX, and began teaching it in various companies throughout the country, including at an IBM site. I turned the course into a book which I published and sold directly on one of my websites until 2004. When I became aware of On Demand publishing, I updated my book, converted it to electronic format and published it in 2012.

The ONLY reliable source
By Richard C. Forcier
I have taught REXX programming for more than 15 years. I have taught it in several countries besides the USA. Gabe's book is the ONLY definitive resource for developing REXX prowess on you own, or after taking a class. His examples are great. I consider it a worthwhile investment in your IT career.

Knows his stuff!
By Michael
Gargiulo explains how REXX works. No jargon. Clear language.
I had to maintain a few old REXX programs without any training. Not a smart situation.
I use this book every day on my job, and it has really helped me.
I couldn't figure out EXECIO on my own but the examples in the book really helped.
There's a web page with practice problems and solutions. I'll probably do one or two in my spare time. (Not much of that!)

Fantastic book
By Marc
Much better than his first book.
I had "REXX in the TSO Environment" when it first came out. It was good,
but not always very clear.
This is better. A lot clearer. The long discussion of the STACK has been
shortened. It gives you all you need to know about the STACK and leaves
you with a warning about using it too much.
I like the part about Error Traps.
