Too often, programmer training ends before you've had time to master all the vital elements of CICS. You're expected to figure out the rest on your own. And with this book, you can! It teaches you the advanced CICS features you'll use regularly (though you won't need all of them in every program):
how to use browse commands to process a file sequentially
how to use the browse commands to process VSAM alternate index files
how DB2 database processing affects CICS programming (if you don't have any DB2 experience, this is just an introduction; you can get the additional DB2 training you'll need from our two-part DB2 series, DB2 for the COBOL Programmer, Part 1 and Part 2)
how DL/I database processing affects CICS programming (again, this is an introduction; you can get the additional DL/I training you'll need from our book, IMS for the COBOL Programmer, Part 1)
how to produce multi-page output using BMS page building
how to use the ROUTE command to direct output to one or more terminals
how to use terminal control commands that let you communicate directly with a terminal, bypassing BMS
how to use temporary storage queues to store and retrieve small amounts of temporary data
how to use transient data queues (transient data exists only from the time it's written to the time it's read)
how to use interval control commands to start a task
how to create an abend exit to keep your task from abending when an error occurs
how to use the distributed processing features of CICS, including Distributed Program Link and APPC
After finishing this book, then, you'll know a wide variety of advanced CICS features. Just as important, though, you'll know what features do similar things and when to use each one. And it's that knowledge that will save you time and work every day.
