CICS Interview Questions And Answers
CICS Interview Questions and Answers will guide us now that CICS (Customer Information Control System) is a transaction server that runs primarily on IBM mainframe systems under z/OS and z/VSE. CICS is a transaction manager designed for rapid, high-volume online processing. This processing is mostly interactive (screen-oriented), but background transactions are possible.

Re: CICS Interview Questions And Answers
I want share some my ideals. I hope it's useful:
1.What is the difference between START and XCTL?
START is used to start a new task. It is a interval control command. XCTL is used to pass control to a program within the same task. It is a program control command.
2.Can you access QSAM (seq) files from CICS?
