Re^3: In-place file filtering

Fair point. Might be worth dropping a bug-report/patch to Abigail-II.

Where do you get the info on which US codes are valid/invalid?

To actually get the list of zip codes costs money, either from the USPS or other sources. However, by repeatedly typing in zip codes into the zip code locator as USPS.com I found out the valid upper and lower bounds.

Don't new codes get added? In other countries valid/invalid codes aren't contiguous sequences. I'd assumed that the lower/upper bounds were part of the spec? If not I'm not sure I'd rely on all the codes outside those bounds being invalid if it were me.	[reply]

Your friendly snail-mail corp will sell you same (sorta' -- they'll sell list of valid zips, from which one can deduce the 5 digit #s which are NOT valid.) But bigbuck$$$$.	[reply]
