Dave Fanning may already have answered this question. If so, forgive.

Look at the _REF_EXTRA keyword. See 'Keyword Inheritance' in the
online help. Not having used it, I'm not completely sure it will fit

*values* of the keyword parameters to the called routine when using
_ref_extra.

How can one return anything from the cleanup routine of an object?
