StreetFinder 1.01 - is a 6K package which implements the Manhattan Address
Locator algorithm found in the NYNEX Yellow Pages. Given an avenue name and a
building number in Manhattan, StreetFinder will tell you the nearest
cross-street. It also does a similar thing for addresses on side-streets: it can
tell you (roughly) the nearest avenue. Freeware. by Alan Simon
