What happens if I try to access a record beyond the total number of records in a table in a COBOL-DB2 program?

In a COBOL-DB2 program, if you try to access a record beyond the total number of records in a table, it may result in an "end of file" condition. This means that you have reached the end of the result set or table, and there are no more records to retrieve.

When this occurs, the program should handle the situation gracefully by checking for end of file condition after each FETCH operation. You can use condition handling mechanisms in COBOL, such as the use of SQLCODE or SQLSTATE values, to detect and appropriately respond to such situations.

By implementing proper error handling and validation in your COBOL-DB2 program, you can ensure that it functions correctly and efficiently, even when accessing records beyond the total number of records in a table.
