## Description

> Macro (excerpt)
> 
> Creates a named lock. Scripts using the same lock key will be blocked and wait for the current script to release the lock.  Note that this does not prevent the issue from being edited or otherwise changed by other means or plugins. This lock only makes sense for the SIL scripts. Locks will be cleared at the termination of the script or when the script currently holding the lock calls sysUnlock(lockKey). Also note also the locks are not guaranteed to be re-entrant.

Creates a named lock. Scripts using the same lock key will be blocked and wait for the current script to release the lock.

```javascript
use "system";
