Common ABEND Codes in COBOL

1. S0C4 – Protection Exception (Storage Violation)

• Cause: Attempt to access restricted or unallocated memory, misaligned data access, or out-of-range subscripts.
• Solution: Verify subscript ranges, ensure proper memory allocation, and check file status codes before accessing records.

2. S0C7 – Data Exception (Decimal or Numeric Error)

• Cause: Invalid numeric data in a computational field or moving alphanumeric data to a numeric field.
• Solution: Validate input data, use NUMERIC CHECK routines, and ensure data integrity.

3. S222 – Job Cancelled by Operator

• Cause: The job exceeded system limits or was manually canceled.
• Solution: Optimize job execution and review system logs for operator messages.

4. S322 – Time Limit Exceeded

• Cause: The job exceeded its allocated CPU time.
• Solution: Optimize loops and file handling, or request more CPU time allocation in JCL.

5. S806 – Load Module Not Found

• Cause: The program or subroutine specified in JCL or CALL statement is missing.
• Solution: Ensure the correct program is compiled and available in the load library, and verify STEPLIB or JOBLIB parameters.

6. S837 – Space Issue (Out of Extents)

• Cause: A dataset exceeded its allocated space and available extents.
• Solution: Allocate more primary and secondary space, and use multi-volume datasets if necessary.

7. S913 – Security Violation

• Cause: Insufficient permissions to access a dataset or resource.
• Solution: Ensure correct RACF (or equivalent security system) permissions.

8. S0C1 – Operation Exception

• Cause: Invalid machine instruction due to an unloaded module or incorrect memory address branching.
• Solution: Ensure all subprograms are properly compiled and linked.

9. U4038 – COBOL Runtime Error

• Cause: Runtime issues such as file open errors, missing DD statements, or logic errors.
• Solution: Check SYSOUT and system logs for specific error messages.
