Here's your guide to writing or maintaining IMS/DC
programs, interactive programs that access IMS databases
under the data communications component of IMS.
To begin, you'll learn all the COBOL considerations
for DC programs—from the COBOL elements themselves
to the coding techniques that work best for DC programs
to testing using the Batch Terminal Simulator (BTS),
a tool that lets you test using IMS resources without
disrupting production IMS processing.
But that's not all. This book also covers Message
Format Service (MFS), which serves as an interface between
your I/O coding and the screen I/O. So you'll learn
how to use MFS to format user-friendly screens. And
you'll learn what tasks you can handle easily through
MFS instead of having to code for them in your DC programs.
