The 'opened' property

Boolean scalar

Valid for: All objects

The opened property is 1 if the object is currently open, and 0 if it is closed. For all objects except the System object, you can set the value of opened in order to force the object to open or close. Setting it to 1 is equivalent to calling the Open method, and setting it to 0 is equivalent to calling the Close method with an argument of 1 (unconditional close).
