CICS Application Programming Advanced

This course teaches advanced CICS programming concepts.

This course is intended for experienced CICS application programmers with a good basic understanding of CICS concepts and commands. Attending this class will lead to a better understanding of CICS application programming, at the advanced level, and a greater knowledge of the CICS application programming facilities.

Some experience of CICS application programming is assumed. Ideally, delegates will have attended our CICS Application Programming course.

This hands on course is designed to increase the knowledge and productivity of CICS application programmers by introducing advanced CICS programming concepts in temporary storage, transient data, interval control and many other CICS functions. Attendees will also be introduced to CICS design techniques, management of storage and task control which will help their development of advanced programming skills.
