   KILL id[,id[,...]]

The KILL command terminates the execution of a thread, thereby stopping its execution and returning it to a “terminated” state. This command occurs regardless of what the thread is doing; therefore, it can cause processes or procedures to fail. Any thread can be killed at any time, as long as it is active. If a thread is not active, killing it will have no effect. You can interrupt a set of threads contained in an array by supplying the array name.

  KILL handleThread
