This option is used to lock, unlock, or display locked files.
Files can be locked or unlocked for all users or for all but utility/EXF users. Once locked for all users, a file cannot be unlocked for utility users only.
Locking is immediate: a transaction in process whose file becomes locked will be backed out.
Unlocking makes the file available again for normal use.
Equivalent direct commands are
LOCK FILE
UNLOCK FILE
