Who this book is for
This book is for COBOL programmers on MVS or VSE systems who need to know
how to access and process DL/I databases in their programs.
By the way, both MVS and VSE allow for DL/I database, or DB, processing,
which is what this book covers. On an MVS system, though, DL/I is part of
a product called IMS/VS, which also allows for data communications, or DC
processing. That's taught in IMS
for COBOL, Part 2.
