DATABASE.0
U.S. Zipcodes
The enclosed file, DATABASE.0, contains 1478 entries. It consists of
those cities in the United States with urban populations at or greater than
20,000. Urban populations are defined as thos cities which are incorporated
as cities, villages and towns. Sources for this information are the NeW York
Telephone Company, U.S. Postal Service and the U.S. Bureau of the Census.
Cities not listed, did not have a minimum of 20,000 population according to the
1980 Bureau of the Census data.
As you probably know, the MSYS BBS written by Mike Pechura, WA8BXN, offers
the "G" command used for user-searches on specific files based upon specific
words and/or phrases. The default database (which does not exist in the
distribution of MSYS) is DATABASE.0. This database, therefore, could be
incorporated as DATABASE.0 and would, therefore, allow users to search for
proper zipcodes cross-referenced to the applicable cities/states. As example,
this would serve the NTS community when sending NTS traffic with the syntax
ST <zipcode> @ NTSxx
if the zipcode was unknown to him or her. A quick access of this file with
the "G" command would probably yield the info being sought.
To use this database, simply copy this 36KB file, already labeled
DATABASE.0, to the FILES subdirectory of your MSYS BBS. Its as simple as that.
The information is, then, immediately available to your users.
Its also recommended that you provide, in that same FILES subdirectory,
a quick HELP file (perhaps called DATABASE.HLP) which would list the contents
of various databases you migh have available. In this way, users could choose
databases other than the default database (DATABASE.0) on which to search.
Although there's no guaranty offered for accuracy, a substantial degree
of caution was used in the preparation of this data. If users can't locate
a city with this database, odds are that the population IN 1980 was under the
20,000 cut-off point.
If you find this useful, please let me know. I'm thinking, next of
including the same data for Canadian cities since they, too, use zipcodes for
NTS routing on packet.
