This diskette contains the ZIPKEY zipcode directory and keyboard 
enhancement program.  Please feel free to distribute the program 
by uploading it to bulletin-board systems, and by copying and 
distributing the diskette to anyone interested. 

You can run the program by putting ZIPKEY.EXE and ZIPKEY.OVL 
into your current directory, and typing ZIPKEY to the MS-DOS 
command prompt. 


What's New In This Version

I have added telephone area codes to ZIPKEY's database.

Now when you specify a zipcode or a city, you'll also get
the telephone area code displayed in ZIPKEY's window.  You
can "play back" the area code with the T specifier in your
hotkey or exit key configuration.

Conversely, you can type a left bracket [ followed by an
area code to ZIPKEY's window to obtain the location of the
area code.

Of course, the data itself is updated every month.  The 
evaluation data is constrained to be at least six months old, so 
that you're now getting the data provided to registered users 
six months ago. 


File Name Conventions for BBS Uploading

If you distribute files in a compressed format, using PKZIP, 
ARC, ZOO, or a similar program, I recommend that the evaluation 
ZIPKEY.EXE file and the manual ZIPKEY.DOC/ZPROG.DOC be packed 
together into one file, and the ZIPKEY.OVL file be provided as a 
second file. 

If you are a BBS sysop, with the ability to delete files on your 
BBS, you can maintain the single name ZIPKEY for the package. 
The compressed EXE-and-manual file can have the extension (.ZIP, 
.ARC, etc.) reflecting the compressing program used.  The OVL 
file can keep its name ZIPKEY.OVL. ZIPKEY.OVL does not need to 
be compressed-- it's already so compact that there is little or 
no further gain from compression. 

If you are uploading to a BBS on which you cannot delete the 
previous version, I suggest that the names contain the version 
information. The EXE-and-manual file should be named ZKxxx, where 
xxx is the ZIPKEY.EXE version number -- for example, ZK200.ZIP for 
ZIPKEY V2.00e.  The ZIPKEY.OVL file should be stored using a 
compression program (not for the compression, which is minimal, 
but so that the file will be named ZIPKEY.OVL again when it is 
extracted). The compressed OVL file should be named ZKmmyy, 
where mm is the 2-digit month and yy is the year of the ZIPKEY 
database -- for example, ZK0890.ZIP for the August, 1990 
version of the data. 

Here are sample directory lines for ZIP files, including 
recommended comment lines: 

ZK200.ZIP        ZIPKEY zipcode dir V2.00 prog/doc,1 of 2
ZK0890.ZIP       ZIPKEY.OVL 08/90 zipcode data,    2 of 2

Note that the data file does NOT contain the program version 
number in its comment line.  I release new data files more often 
than new program versions, so that the data file is not married 
to the program version number.  People can download new data 
files even if they already have the latest program version.
