If you're new to CICS programming, the last thing you need is a long-winded explanation of every nuance and detail of the system's operation. The first thing you need is the CICS/ESA Primer. It puts your hands on the keyboard quickly—even if you have no previous online experience—and provides loads of diagrams, screen shots, and code, as well as crisp, clear explanations of the basics of CICS programming. In practically no time, you'll learn everything you need to know about:

CICS screen design
Basic Mapping Support (BMS)
Program function keys
Debugging techniques
File updating
Creating a simple menu

And that's not all! This is the only introduction that includes an entire section on CICS and client/server technology, the topic that has companies clamoring for CICS-trained programmers. But whether you're working on client/server or mainframe systems, this book helps you master the fundamentals and prepare for more advanced material.
