What we need to know to understand this book

To write message queuing applications using WebSphere MQ, we need to know how to write programs in one of the supported programming languages:

• C or COBOL (available on all supported platforms)

• PL/I (available on z/OS only)

• z/OS assembler (available on z/OS only)

• Visual Basic (Windows systems only)

If the applications you are writing are to run within CICS system, you must also be familiar with CICS on your platform and its application programming interface. To understand this book, you do not need to have written message queuing programs before.
