Types of CICS Tasks and Role of EXEC CICS START

In CICS, there are several types of tasks that can be initiated:

• Transient Data Tasks
• Interval Control Program (ICP) Tasks
• Long Running Tasks
• Batch Tasks

The EXEC CICS START command is used to initiate a task within a CICS region. It allows a program to start a new task asynchronously, while the existing task continues to run. This is particularly useful for handling concurrent processes in a CICS environment.

By using EXEC CICS START, a program can spawn a new task and pass control to it, enabling parallel processing and efficient utilization of resources within the CICS system.
