Hello, Frank Barknecht a écrit : However messages reaching a message box do not
carry such an unique identifier, as $0 is a property of the canvas, not a property of the incoming message: There is no $0 in messages, there's only a $0 in a canvas. An effect of this is, that there's no $0 in message boxes, but there's a $0 in object boxes. So to get $0...

I was just wondering why $0 wouldn't be implemented as a message property.
Message boxes couldn't be drawn anywhere else than into a canvas, so I really don't get why canvas properties wouldn't be parsed through message boxes with some variable, and then the $0 would be an excellent guest for the canvas's unique identifier into messages.
