How does COBOL handle record locking when multiple programs access the same file in "I-O" mode?
- COBOL automatically handles record locking, preventing conflicts
- COBOL doesn't support record locking in "I-O" mode
- COBOL relies on the operating system for record locking
- COBOL uses exclusive lock, allowing only one program to access the file at a time
COBOL typically relies on the underlying operating system for record locking when multiple programs access the same file in "I-O" (Input-Output) mode. It doesn't inherently provide built-in record locking mechanisms.
