The front papers neglect previous editions. This is exciting news about a reliable product. Please try to keep up.

Hi Christopher, We wrote this book at the z/OS V1.12 level. We did not single out the enhancements to VSAM in each z/OS release since those are specifically addressed in the DFSMS Release Guides.

In a few places in the book, sample code is shown as:
TM SMF64SMB,X’80’ SMB USED?
to find out if SMB is being used or not. I believe both bits 0 and 1 should be tested to find out if SMB is in use or not, not only bit 0.
So, this should probably be used instead:
TM SMF64SMB,X’C0’ SMB USED

I downloaded this book and started at Chapter 1.
Section 1.1 told me that VSAM stood for
Virtual Sequential Access Method. Huh?
I started working on S/370 in 1975 and one of the things I learned that year was that Virtual Storage was the new thing and that VSAM worked with Virtual Storage and VSAM was the Virtual Storage Access Method.
This is borne out by the glossary in the latest DFSMS Introduction manual. Look up VSAM and see!
