smile_rajeev,

Let me explain the concept of task and Transid and programs in relation to PCT.

A task is the basic unit of system activity that is managed by cics. The resources of the system, such as stirage and cpu cycles, are allocated among all the tasks in the system, using various strategies to optimize throughput and response time.

A task is an invocation of particular transaction. Transactions are identified to cics by a transaction identifier(transid) of 1-4 characters, listed in the program control table(PCT). A given transaction may be execueted many times during the course of a day, each execuetion is a different task.

Each transid listed in the PCT is associated with a program.when a transaction is invoked(by specifying its transid), it is a request to cics to execuete the associated program.

The primary function of the PCT is to register the control information of all CICS transactions. PCT contains a list of valid Trans-id paired with the name of a program CICS will load when the transaction is initiated with that transaction identifier. It identifies priority and security level (RSLC) of transaction.

The difference between transaction and task is that while several users may invoke the same transaction, each initiates a separate task.

Hope this helps...

Cheers
