Selects the locking implementation to be used.

Restriction: These tunables are supported for native COBOL only.

Syntax:

>>-----set lock_mode=---.-0-.-----------><
                        +-1-+
                        +-2-+
                        +-3-+ (UNIX)

0	Uses the locking mechanism provided by Micro Focus COBOL V3.1 and earlier versions.
1	Provides compatibility with DOS and OS/2 locking mechanisms.
2	Provides interlanguage locking. This method causes record locks to lock the physical record.
3 (applies to UNIX environments only)	Provides compatibility with C-ISAM version 5 and above.

Default:	1 (Windows) or 2 (UNIX)
IDE equivalent:	Project > Properties > Micro Focus > Run-time Configuration > File Handling > Lock mode strategy

This tunable is only applicable if the File Handler configuration option FILEMAXSIZE is set to 4.
