1. Please link **current** documentation. v8.0 is dead, dead, dead.

1. You cannot call this function from the designer script console. It is available in gateway scope only. (And Perspective, which is an extension of gateway scope.)

(Use a gateway message handler to call the function. In the designer, use `system.util.sendRequest()` to invoke it.)
