AppleScript: The Definitive Guide, Second Edition by Matt Neuburg The unconfirmed error reports are from readers. They have not yet been approved or disproved by the author or editor and represent solely the opinion of the reader. Here's a key to the markup: [page-number]: serious technical mistake {page-number}: minor technical mistake : important language/formatting problem (page-number): language change or minor formatting problem ?page-number?: reader question or request for clarification This page was updated March 26, 2007. UNCONFIRMED errors and comments from readers: (111) 5th paragraph; This sentence: "When a script property is initialized to a value where this makes a difference (a list, a record, a date, or a script object) it is set by reference (see ...etc)". I understand what is intended (by reference vs by value, etc) but the "where this makes a difference" is a bit enigmatic (surely, setting a scalar also "makes a difference") and I wonder if there was a typo.
