>Well I'm not quite clear on what the rules are, but at least this way you can bind multiple properties to the same method, and the method would know the name and value of the property which changed. If you need something else, then I solved the problem you didn't have :).

Oh, my problem is that I have method that needs the value from a property. What property is not fixed. The method is used independend of the change of the property. I have more changes then uses. And I have more time on the use then on the change, for that. That defines the rules - as less calls to EVAL or GETPEM as possible.

You helped with the solution - by bringing up GETPEM. :)
