						<<adrcalendar is the address of a valid calendar structure.
						<<We return the date corresponding to the address of the first element in the calendar.
						<<We throw a scriptError if adrcalendar does not point to a valid non-empty calendar structure.
						<<We call mainResponder.calendar.getFirstAddress to do the actual work.
						<<This script is called from mainResponder.calendar.getMostRecentAddress and mainResponder.calendar.getMostRecentDay to perform bounds checking.

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.
