Specifies the type of record locking.
| 0 | Programs can read locked records, but not access them in other ways. This is the standard method with this COBOL system. |
| 1 | Programs cannot access locked records at all. This is as in languages other than COBOL. |
| 2 | Creates a new file with the same basename as the file being opened but with a .lck extension. Any record locks are recorded in this file. This enables the File Handler to read and write to files up to 4 gigabytes in size regardless of whether the file is shared or locked. You cannot set this value for striped files. |
