This diskette contains the ZIPKEY zipcode directory and
keyboard enhancement program. Please feel free to distribute
the files by uploading them to bulletin-board systems, and by
copying and distributing the diskette to anyone interested.
You can run ZIPKEY 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
ZIPKEY V2.04 fixes a few minor bugs.
If you have DOS V3.0 or later, ZIPKEY V2.03 can now find its
auxiliary files in the same directory from which ZIPKEY was
invoked, so you don't need to change the current directory
to install ZIPKEY in memory or run it in non-resident mode.
With V2.00 I 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,
ZK204.ZIP for ZIPKEY V2.04e. 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, ZK0592.ZIP for the
May, 1992 version of the data.
Here are sample directory lines for ZIP files, including
recommended comment lines:
ZK204.ZIP ZIPKEY zipcode dir V2.04 prog/doc,1 of 2
ZK0592.ZIP ZIPKEY.OVL 05/92 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.
