Therefore when the form.unload contains DODEFAULT() (or no code), the parent class Unload() fires and returns a value only to the next level down the heirarchy. If that next level doesn't do anything with the value, it will be lost before the bottom-level form.unload() fires. (Hope this makes sense!)

Hi Alan,

Your analysis and solution is correct.

* If in the subclass method you've only 
DODEFAULT() 
* is the same as 
DODEFAULT() 
RETURN

As you can see return value from the parent class code is lost in this case.
