						<<adrcalendar is the address of a valid calendar structure.
						<<d is an optional date which defaults to clock.now ().
						<<If the address corresponding to d exists, we return it.
						<<Otherwise we walk backwards in time until we find an element and return its address.
						<<We throw a scriptError if the calendar does not contain elements corresponding to times before d or if adrcalendar does not point to a valid non-empty calendar structure.

This listing is for code that runs in the OPML Editor environment. I created these listings because I wanted the search engines to index it, so that when I want to look up something in my codebase I don't have to use the much slower search functionality in my object database. Dave Winer.
