Matcher: An Archive Utility Program

We have all had the experience of receiving 2 or 3 copies of the same catalog each with a slightly different version of our address on it. Mail order companies buy address databases from many sources and often the same address may be in more than one in a slightly different form. This fools the company into mailing multiple catalogs to the same address. Even a simple weeding of addresses would save a lot of mailing and printing costs. There is no doubt that having a database of specialized information can be an extremely valuable commodity. But one also needs to have the programming power to screen the data and verify its consistency.
