3.3 Error

Error( messages... )

Error signals an error. First the messages messages are printed, this is done exactly as if Print (see Print) were called with these arguments. Then a break loop (see Break Loops) is entered, unless the standard error output is not connected to a terminal. You can leave this break loop with return; to continue execution with the statement following the call to Error.
