Question is as in the title - I'm ignoring the error from the Close Reference (and not checking the reference exists) since I gather that does nothing useful (assuming a case structure and Is A Refnum test) but I'm wondering if it's possible that since execution order isn't enforced here, I could possibly write the new reference first, and then close the old reference (I realize a different reference is passed into the CS, but I don't know how Close Reference works - perhaps it closes based on a memory location etc.)
