If you're new to CICS, by the end of chapter 2, you'll see how a complete CICS program works, so you'll understand all the pieces involved. And by the end of section 2 (just 6 chapters), you'll be able to design, code, and test pseudo-conversational CICS programs on your own.
But that's just the beginning. Whether you're a new or experienced programmer, the rest of the book covers features that enhance your skills and answer the questions that crop up on the job every day.
To be specific, section 3 presents additional commands and techniques you'll use regularly. Then, section 4 presents a complete CICS application made up of 4 interrelated programs. Once you understand the design, BMS mapsets, and COBOL code for these programs, you'll have the skills of an entry-level CICS programmer in industry.
The last two sections present commands and skills you can learn in whatever sequence you prefer. Section 5 shows you how to process files and DB2 databases (essential skills in any CICS shop). And section 6 gives you an overview of other CICS features and skills that you should know about, even if you don't use them every day.
Of particular interest are chapters 20 and 21 in section 6 because they give you a view of where CICS is headed. In chapter 20, you'll learn how to design, code, and test CICS programs in which the "presentation logic" (all the functions related to sending data to and from the terminal)is separated from the "business logic" (the functions that process the data). That way, you can use CICS for what it does best-transaction processing on the mainframe-while languages like Java or Visual Basic are used for the user interface. In chapter 21, you'll see that this approach can also be used for web applications, making CICS a more flexible transaction processor for the enterprise applications of the future.
All of the content is presented in an innovative way, with the coding details and examples for each feature on the right-hand page and added perspective on the left. This is a real time-saver, both when you're learning CICS in the first place, and when you're looking up information or coding details later on.
