From this and later remarks, it is obvious that you are a Quiche Eater. I expect that you even think that integer overflow is an error to be avoided, instead of an opportunity for creative uses of computed GOTO.

It's evenly divisible by 13 and by 1. It's also (not evenly) divisible by any non-zero real number that you care to think of, and also by numbers that you can only imagine.

Many financial systems have a 13th month (well, usually called "period 13") every year for year-end closing transactions. Sometimes it even has a day in the calendar, and using it can be interesting... It has been noted that we have received a couple of journal entries with a December 31 effective date. This is a reminder that using that date will post the journal entry to Period 13. Period 13 is reserved for business unit collapsing entries and Corporate year end entries. http://thedailywtf.com/Articles/Nobody-Does-Business-on-December-31st!.aspx -- I worry that 10 or 15 years from now, [my daughter] will come to me and say 'Daddy, where were you when they took freedom of the press away from the Internet?'
