Close by Handle

Hello all,

Is there an alternative to the close() function where I can use the Handle() of a window?
In the Windev help I can only find the close() function which is only compatible by the window name.

I would like to create something like this:

id is system int = Handle(CurrentWindow())

"Close the window"
Close(id)

Or is there some function which translates the Handle to window name?

Best Regards,
Rik
