This function is ignored in Windows, as it would cause all scripts to hang, but is maintained for compatibility. Instead, you can use a `.TimerAfter` timer, like this: .TimerAfter (3, `some_code); For example, to call the "myMethod" method with no arguments: .TimerAfter(3, `(@self).myMethod()); Or, for example, to print "end": .TimerAfter(3, `princ("end\n"));
