>>Tom Rettig's envlib.prg does this in .init() - saves the current value to this.oldval, and sets the date (or any other setting, there's a subclass for each) to whatever is passed as parameter to init. Pretty much the same idea, but saves you one line when calling - and that's 50% of the lines you need to write :).

His classes do that in their .init()s, and you create them in your form's .load() and assign them to some property of something on your form (or the big object with all the settings) so they have a reference on the form and don't revert everything when they get out of scope.
