> What signal does clicking a Win9x DOS box's close box generate?

Via $2f interrupt (see unit below and the Interrupt List
http://www.ctyme.com/rbrown.htm). Also possible to change
the Window title & subtitle. Win3.x+ also allows transferring
the clipboard! Example in... http://members.xoom.com/gdemont/edit.htm
