CICS is the world−class transaction processor thats used on IBM mainframe computers. In fact, CICS systems are used to handle billions (yes, billions) of online transactions every day for banks, airlines, insurance companies, hospitals, e−business siteseven the Olympics. So when you withdraw money from an ATM, place an airline reservation, or order a product over the Internet, chances are that CICS has been used to process your transaction.

The vast majority of the CICS code for those applications is in the form of CICS commands that areembedded within COBOL programs, which is why this book is called CICS for the COBOL Programmer. Today, there are close to a million CICS programmers, and they are among the highest paid programmers. These programmers not only maintain the billions of lines of CICS code that is currently in operation, but they also develop new CICS applications. In fact, CICS can now be used as the transaction processor for applications that have user interfaces written in languages like Java and Visual Basic or that run in a Web browser. In short, CICS programming is a valuable skill today, and CICS is going to continue to be the transaction processor for enterprise applications of the future.
