Given that you would likely want to do this test with a binary search I don't see any reason why it should be slow (effectively you can do the entire search with about 17*k compares). The bigger concern with validation would be in having the complete list of zip codes to validate against. It might make more sense to see if your weather service can "fast fail" on an invalid zip code, since they will likely maintain a valid zip code list, and if you do it yourself you would want to maintain the same one they do. -- David Duncan Apple DTS Animation and Printing _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
