unlock-file command

.md

The unlock-file command clears file locks which have not been cleared through normal system operation.

File locks are set by BASIC filelock statements and other mechanisms, and provide a means of assuring data reliability by preventing one process from updating a file while another process examines a batch of records from that same file.

File locks are displayed by list-locks as special item locks with an item-ID of an asterisk and a hash of 0.

Note: A clear-locks (I or a clear-locks releases all file locks.

Syntax

Parameter(s)
