Differences between EIBRESP and EIBRESP2 in CICS

In CICS, EIBRESP and EIBRESP2 are fields in the Executive Interface Block (EIB) that provide information about the status of the last command executed.

EIBRESP is a one-byte field that indicates the response code of the last command. It can have values ranging from 0 to 255, with 0 indicating successful completion and non-zero values indicating errors or exceptions.

EIBRESP2 is a two-byte field that provides additional information about the last command's response. It is used in conjunction with EIBRESP to offer more detailed error information, such as specific error codes or messages.

While EIBRESP provides the primary response code, EIBRESP2 offers secondary details that can help in diagnosing and troubleshooting errors in CICS applications.

Focus Keyword: EIBRESP vs EIBRESP2 in CICS

When working with CICS (Customer Information Control System), it's important to understand the distinctions between EIBRESP and EIBRESP2.

EIBRESP:

• EIBRESP stands for EXEC Interface Block Response Code.
• It is a single byte field that indicates the outcome of an EXEC CICS command.
• EIBRESP is a general response code that signals the success or failure of an operation.
• Its values range from 0 to 255, with 0 typically indicating success and other values representing different types of errors.

EIBRESP2:

• EIBRESP2 is an additional two-byte field that provides more detailed information in case of errors.
• This field can be used to give specific error details beyond what EIBRESP provides.
• EIBRESP2 is often used in conjunction with EIBRESP to troubleshoot and diagnose problems more accurately.

Therefore, while EIBRESP gives a general indication of success or failure, EIBRESP2 offers more specific error information for better problem analysis in CICS programming.
