What is the difference between a COMMAREA and a EIBRESP field in CICS

In CICS, the COMMAREA is a data area used to pass information between a program and a CICS transaction. It is typically used for passing input and output data. On the other hand, the EIBRESP field is a part of the CICS executive interface block (EIB) that contains the response code from CICS indicating the success or failure of the transaction.

While the COMMAREA facilitates data exchange between programs and CICS transactions, the EIBRESP field specifically captures the outcome of the transaction, providing valuable information for error handling and decision-making within the program.
