Releases a logical lock on a variable name.

|varname||Name of the variable to be unlocked.|
Each time a lock is obtained on a varname a lock count is incremented. Unlock decrements this count. Only when the lock count falls to zero will the logical lock be released. For this reason, you should balance each call to Lock with a corresponding call to Unlock.
The following example uses the Lock function to obtain a logical lock on a global variable name (glvn) with a timeout of 10 seconds, and then uses the Unlock function to release the logical lock.
If Lock(^PatientData(PatientID),10) = True Then Println "Got the Lock" Unlock(^PatientData(PatientID)) 'Release the logical lock Else Println "Couldn't get the lock" End If
