ZIPKEY v2.0 by Erik Isaacson Registration $ 25.00

Major update
ZIPKEY zipcode directory program V2.00
ZIPKEY is a complete city-level directory of 5-digit United
States zipcodes and 3-digit telephone area codes, combined
with a keyboard enhancement program. The goal of ZIPKEY is
to provide enough power and flexibility so that no one with
an IBM-PC (or hardware-compatible computer) will ever again
have to manually type in the name of a United States city or
town (at least not one big enough to have its own zipcode).
When run as an ordinary program, ZIPKEY allows you to
instantly access any of the 42000+ zipcodes in the directory,
searching by zipcode, state-and-city, city-only, or area
code. If you want to use ZIPKEY just to occasionally look up
a zipcode or area code, you simply choose main-menu option 2
and follow the prompts.
ZIPKEY achieves its full power when installed permanently in
memory. In this "memory-resident" mode, you can invoke
ZIPKEY from within any other program (a word processor, a
data-base manager, etc.). You can type just a 5-digit
zipcode, and ZIPKEY will fool the program you're running into
thinking that you have typed any or all of the following: the
city name, the state name and/or abbreviation, the zipcode,
the area code, and any other combination of fixed
keystrokes. This "keystroke output" can be in any format
that you wish.
ZIPKEY is completely configurable. You can specify any
combination of keystrokes (the "hotkey") that will invoke
ZIPKEY when you're running another program. You can also
specify alternate hotkeys to allow differing sources of
zipcode specifications (repeat the last zipcode, use a fixed
sequence of first digits, or get the zipcode from your
screen), and/or a differing format when ZIPKEY feeds the
city/state/zip back through your keyboard. You may have up
to 99 different hotkeys. Your configuration is stored in a
disk file, which is automatically read by ZIPKEY whenever it
is invoked.
ZIPKEY has a sophisticated abbreviation algorithm, allowing
you to specify a limit to the length of the city name, so
that it will fit into a fixed field.
ZIPKEY's database is based on data from numerous sources,
including the U.S. Postal Service. It has been extensively
cross-checked to ensure accuracy and consistency. The data
is highly compressed, so it won't occupy very much space on
your disk or in memory. The compression method was
custom-designed for this database, providing for maximum
compaction while retaining instant access. It occupies less
than 128K bytes (less than 3 bytes per entry), small enough
to allow installation of the data base in either LIM-EMS or
main memory. But access to the data is fast enough so that
it is perfectly reasonable to leave the database on your hard
or RAM disk.
