PLEASE read Chapter 1 for legal terms, how to register/subscribe
for the package, and the overview of the program.  Just type
ZIPKEY if you don't like reading manuals.

This DOC file is an entire manual-- over 50 pages.  I have
formatted this file so that it can be printed at 10cpi with
margins.  To save space, I don't have a left margin in the file.
You'll need to set your printer to a one-inch left margin to have
room to punch holes for a ring binder.

If you got ZIPKEY from an XYZ software house, that advertises
great software for $5 per disk, and you are now confused as to
your rights, you might ask the following

QUESTION: "What's going on here?  Have I already bought the
  program, or what?"

ANSWER: Well, no, not exactly.  You've bought a disk that has
  great software on it; unless you legally purchased the
  registered version of ZIPKEY, you haven't bought the software
  yet.  ZIPKEY, like most major software offered by the
  $5-per-disk distribution houses, is free-distribution software
  (also known as "shareware", or "user-supported software").
  That means I retain the rights to ZIPKEY, but I choose to let
  people pass the evaluation copy around.  I have no business
  relationship with any distribution houses in the U.S.; I don't
  get a penny of the $5 (or whatever) you paid them for the disk
  containing ZIPKEY.  So I need and expect to be paid by you,
  because I make my living out of making and supporting shareware
  products.

  Some distribution houses do a pretty poor job of revealing the
  shareware nature of the software they sell.  If you thought you
  had purchased the software free and clear, you might feel
  justified in being angry with them for having misled you.  And
  you might look around for houses that do a better job of
  informing the public.  But I hope you'll take the time to
  consider everybody's role in the shareware marketing scene; if
  you do, I think you'll conclude that although you may have been
  misled, you haven't really been cheated out of anything.

  Shareware is great for authors like me, who have spent all
  their years in their computer holes, learning to be great
  programmers, and no time in business school learning marketing
  and distribution techniques.  We simply cast our programs to
  the winds.  They are distributed at practically no cost to us.
  That's why we can charge a lot less than the cost of
  "commercial" software.
                                                              0-2

  Shareware is also great for customers like you.  You can try
  out the software before paying for it.  You'll know that a
  successful shareware product is good, because only satisfied
  customers pay for it.  The existence of shareware infuses
  healthy competition into the entire software market, for both
  price and quality.  In the case of ZIPKEY, I'm utterly
  convinced that you'll never find a better value for a zipcode
  directory, anywhere.

  Finally, let's consider the distribution houses.  They provide
  a legitimate service, for which they charge a reasonable price.
  The best houses act as librarians, evaluating and cataloguing
  software.  Most pay thousands of dollars for advertising.
  Their cut is far less than the distributor's cut for
  "commercial" software (they prosper because their volume is
  bigger and their support responsibilities are smaller).  Most
  customers for the distribution houses are repeat customers, who
  are aware of, and happy with, what they are getting.  If it
  weren't for your XYZ House, you might never have heard of
  ZIPKEY, or might never have figured out where to obtain it.

  So I hope you'll be happy with shareware, and actively desire
  to support it.  You'll feel good about promoting a healthy
  situation for everybody.  And you'll encourage the best
  programmers in the world to keep writing for you, instead of
  for the big corporations.

Now that I've said that, let's move on to the package.   The
ZIPKEY evaluation package consists of the program ZIPKEY.EXE, the
database file ZIPKEY.OVL, this manual ZIPKEY.DOC, and ZPROG.DOC,
a supplement for programmers.

CHAPTER 6 PROGRAMMATIC INTERFACE

INDEX

CHAPTER 1   INTRODUCTION AND LEGAL TERMS


Installing ZIPKEY from Floppy to Hard Drive

To install ZIPKEY on your hard drive, place the diskette
containing ZIPKEY into your A or B drive and type either
A:INSTALL or B:INSTALL to your DOS command prompt, depending on
which diskette drive you used. The INSTALL program will prompt
you for the various installation options.


Overview of This Manual

Welcome to ZIPKEY!  I've tried to make the ZIPKEY program as
self-explanatory as possible, so that you won't need to consult
this manual very much.  You may simply wish to run INSTALL to set
up the program on your hard drive, and go from there.  But ZIPKEY
is a complex program with a fair number of sophisticated
features.  If you'd like to explore every nook and cranny of
ZIPKEY's functionality, you'll want to read this manual.  It
describes ZIPKEY in more detail than the built-in documentation,
and provides examples you can work through as you read.

Some of this manual (especially in Chapters 2 and 3) tries to do
double duty, as both a tutorial and a reference guide.  A
tutorial is intended to be read from start to finish; it may
contain a thread of discussion that runs from section to section.
A reference guide is intended to be consulted a section at a
time, to look up specific facts; it may repeat information so
that the user doesn't need to read the whole manual to obtain the
desired fact.  I've tried to keep the tutorial-vs.-reference
annoyances to a minimum: the continuing (tutorial) threads are
restricted to the more elaborate examples presented; I hope they
are easy enough to pick up when you consult a section as a
reference.  And I have tried to organize things to keep
repetitions to a minimum, so you can read the manual as a
tutorial.

I would, of course, like you to read this first chapter,
including the legal terms and conditions pertaining to the
program.  Then, if you're just getting started with ZIPKEY, you
should read through Chapter 2 while running ZIPKEY in
demonstration mode, to follow the examples and gain a familiarity
with all of ZIPKEY's search capabilities.  Chapter 3 tells you
how to configure ZIPKEY for memory-resident use, and Chapter 4
tells you how to set up the files on your computer so that ZIPKEY
is permanently available.  Chapter 5 gives you details about
ZIPKEY's built-in facility for creating an order form to
subscribe to ZIPKEY and regularly receive fresh data.  Chapter 6
is for computer programmers who wish to access ZIPKEY's functions
from within their programs.
                                                              1-2

Overview of ZIPKEY

ZIPKEY is a complete city-level directory of 5-digit United
States zipcodes, 3-digit telephone area codes, and time zones,
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 (or just type ZIPS to your
DOS command prompt) and follow the prompts.

ZIPKEY achieves its full power when placed resident in memory.
In this 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, the time zone, 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 placement 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.
                                                              1-3

What ZIPKEY Doesn't Do

ZIPKEY's database doesn't contain street names, so ZIPKEY can't
tell you the exact zipcode for a street address within a city
that has more than one zipcode.  Such a database would occupy
many megabytes, even with ZIPKEY's rate of compression.  Right
now I consider that too big for mass distribution; but when the
technology improves (e.g., when writable CD-ROMs are
commonplace), I may offer such a database.

ZIPKEY has been tested against all the major database managers,
word processors, and spreadsheets, and works fine with the vast
majority of them. But there are some programs that ZIPKEY is
incompatible with.  Here are the problems that I know about and
haven't been able to solve:  Keystroke playback doesn't work
within Microsoft Works 1.0, which apparently ignores the usual
keyboard drivers in your computer; but you can make Works 2.0
work either by choosing "Text" in "Works Settings", or
configuring ZIPKEY to work in graphics mode. ProKey 2.1 causes
problems, but 4.0 works fine.  Microsoft Word 4.0 doesn't allow
typeahead within ZIPKEY's window so you must either disable
intermediate results or type slowly -- Word 5.0 solved this
problem.  NamePal 1.4 has a bug that limits playback to 15
keystrokes.



Operating Requirements

ZIPKEY requires an IBM-PC, IBM-PC AT, or 100% hardware-compatible
computer with at least 256K bytes of memory, running MS-DOS V2.0
or later.  A hard disk is not required but is recommended unless
you have lots of memory to store ZIPKEY's data when it is
resident.

Most of the "clone" computers work fine running ZIPKEY.  The
areas of compatibility needed are in the memory-mapping of the
video interface, the BIOS variables and buffers managing both
video and keyboard, the timer-interrupt hardware, and the
keyboard-interrupt mechanism.  Some computers are compatible
except for the mapping of internal codes passed from the keyboard
to the computer.  For those computers, ZIPKEY will work properly
except during configuration, when the wrong names are displayed
for the hotkeys.


Legal Terms

ZIPKEY is a copyrighted work -- it is not and never has been in
the public domain.  Each release of the ZIPKEY program comes in
two versions: ZIPKEY.EXE, the evaluation copy, may be copied and
distributed to others, subject to the conditions I'm about to
describe.  The other version ZIPKEY.COM, the registered user's
copy, is subject to the same legal restrictions as
traditionally-distributed ("commercial") software.  Neither
version has any physical copy-protection schemes.
                                                              1-4

WARNING: Before installing this or ANY new software, you should
BACK UP any valuable data on your computer system.  ZIPKEY has
been extensively tested on numerous different machines, and it is
believed to be reliable and non-harmful.  However, software is
the most complicated kind of product there is.  No mortal human
can be absolutely and completely certain that a piece of
complicated software will work on any given machine.  So you are
completely responsible for determining the fitness or usability
of this package.  I will not be liable for damages of any kind,
including but not limited to lost sales or profits, arising from
any failure of this package to perform as expected.

If you have the evaluation copy ZIPKEY.EXE, I hereby grant you
permission to install this version of ZIPKEY in its
memory-resident mode for up to one month.  After that, you must
either remove ZIPKEY from your system, or subscribe -- option 5
of the main menu (described in detail in Chapter 5) will create
an order form for you.

If you have the registered copy ZIPKEY.COM, you may install it
only on those computers servicing the keyboards you have
licensed.  You may make copies for backup and archival purposes.
You may not allow the registered copy to be run from more
keyboards than you have licensed.  The license for running ZIPKEY
in its non-memory resident (demonstration) mode is permanent --
you don't need to renew unless and until you want fresh data.
The license for running ZIPKEY in its memory-resident mode
(hotkeys, key playback, and/or program interface) is paid by the
year, according to the rate schedule published in Chapter 5, and
built into the order-form section of ZIPKEY, option 5 of ZIPKEY's
main menu.

A simple registration for a single keyboard, with printed manual
and one disk with the latest data, is $30.  Update disks are $25
apiece.  Again, the license is permanent if you use ZIPKEY only
in demonstration mode; it is good for one year if you use ZIPKEY
in memory-resident mode.

If you are a casual user -- only calling up ZIPKEY occasionally
in non-memory-resident mode for private, non-commercial use --
then your subscription is optional.  You may send however much
money you feel the program is worth to you.  If you send $30
($31.50 in Indiana), you'll get the printed manual and a disk
with the registered version of the program and the most current
database.  Your support is much appreciated, and will encourage
the continued production of high-quality "try before you buy"
software.

I reserve the legal right to change legal terms and prices for
future versions without prior notice.  At the present time I have
no plans to change prices until inflation has seriously reduced
the value of the dollar (say, when the price of unleaded regular
gasoline goes over $1.50).  I will never consider you committed
to a higher price before being advised of the price-- you'll
always have the option to cancel your subscription and receive a
refund for unused time.
                                                              1-5

Legal Conditions for Free Distribution

Here are the conditions for free distribution of the evaluation
version of ZIPKEY:

1. You may copy the disk-file version of this manual, the
   evaluation version ZIPKEY.EXE, and any version of ZIPKEY.OVL
   more than six months old, and give them to anyone who accepts
   all the legal terms spelled out in this chapter.  The copies
   you distribute must be complete and unmodified.  You are
   specifically prohibited from distributing the ZIPKEY.OVL data
   in any unpacked format, or any format other than ZIPKEY.OVL.

   Each ZIPKEY.OVL file that I distribute begins with a copyright
   message containing the date after which the file can be
   distributed freely.

2. No part of ZIPKEY may be sold to anyone without my prior
   written permission.  If the package is distributed on a
   diskette, any fees collected must be specified as
   materials/handling, and may not exceed $10 for the diskette.
   Thus, I am allowing shareware distribution houses to
   distribute the evaluation version of ZIPKEY, as long as they
   don't try to deceive their customers into thinking they have
   bought the full rights to the program.

3. I reserve the right to prohibit specific individuals and/or
   companies from distributing any or all of my copyrighted
   works.  If I exercise this right, I shall inform such
   individuals/companies in writing, by certified letter.

   So far, I have exercised this right against only one company,
   Sizzleware.  They received a prohibition against distributing
   my A86/D86 packages after they marked the packages Public
   Domain in their catalog, and then neglected to change the
   entry in the next catalog.  The subsequent catalog was
   published three months after I wrote them and they wrote back
   saying they would make the change.  It is my impression that
   this was sheer carelessness on their part; but the mistake,
   particularly after they were notified and had three months to
   correct it, was a grave one.  I considered the prohibition
   necessary to protect my copyright.  The prohibition was lifted
   when they published a catalog with a corrected entry for
   A86/D86.
                                                              1-6

Sources and Copyright Status of ZIPKEY's Database

ZIPKEY's database consists of over 42000 zipcode entries,
covering over 31000 different cities and towns.  It was created
using numerous different references, most notably the data files
provided by the U.S. Postal Service correlated against the cities
and zipcodes from the 150000-entry database of a fair-sized mail
order firm.  The latter "real-world" data provided much better
accuracy in terms of the city names people actually use for their
own addresses, as opposed to the Postal Service's
officially-designated "primary city" for a zipcode.  The
following references were also used, as a part of an extensive
cross-checking and verification effort:

   * maps and lists from several dozen telephone directories

   * U.S. Census data files

   * USPS National Five-Digit Zip Code & Post Office Directory

   * AAA Road Atlas

   * Rand McNally Commercial Atlas and Marketing Guide

   * National Atlas of the United States of America

   * Rand McNally Road Atlas

   * Bellcore Telephone Area Code Directory

   * ATT's ZIP-PHONE files

The resulting ZIPKEY database differs by thousands of entries
from any database that could be derived by mechanical means from
any of the sources I have mentioned.  It is much more accurate
than any of the sources for its purpose: to provide the city name
actually used by the most people in a given zipcode.

So the ZIPKEY database contains a large body of information that
is public knowledge, but at the same time represents a
substantial creative compilation effort.  It enjoys the same
copyright protection as other reference works, such as
dictionaries, that contain compilation effort.  You may use the
ZIPKEY database as a reference source, but you cannot simply
unpack and publish the database without independently
cross-checking and verifying the entire work, and adding
substantial effort to make it your own.  If you do such
unverified publishing, you will be in violation of federal
criminal copyright law.
                                                              1-7

Note that a skilled programmer can use ZIPKEY's programmatic
interface to unpack ZIPKEY.OVL into an ASCII format.  Again, I
emphasize that the data in ASCII still contains my creative
compilation effort, and is still under my copyright.  You may
create and manipulate such a data file from the keyboards for
which ZIPKEY is licensed, but you are specifically prohibited
from distributing such data to non-licensed computers, or in any
printed format.


Difference Between the Evaluation and Registered Versions

The evaluation copy of ZIPKEY has full functionality.  The only
differences between the evaluation and registered versions are as
follows:

1. The evaluation version is distributed as an EXE file, and the
   registered version is distributed as a COM file.

2. The version number, that appears on the console when ZIPKEY is
   run and also on the signon popup window, has an "e" appended
   to it for the evaluation copy.

3. Some of the help messages of the program are different, to
   reflect the program's registered vs. evaluation status.  But
   there is no missing information in the evaluation copy.

4. When you issue the ZIPKEY 4 command (typically in AUTOEXEC.BAT
   when the computer is started up), the evaluation copy of
   ZIPKEY will check dates before it executes your command to
   place ZIPKEY resident in memory.  If it is now the second
   month after you have created a ZC file, ZIPKEY reminds you
   that you need to register, and invites you to fill out an
   order form.  You can type N to the invitation and ZIPKEY will
   go resident normally and work just fine.  I'm just hoping
   you'll get tired of having to type that N every time you start
   your computer, and send for the registered copy.

5. The evaluation copy will refuse to read a ZIPKEY.OVL database
   whose free distribution is not yet allowed (less than six
   months old).  If everyone follows the distribution rules, this
   prohibition should never be encountered.  If you do encounter
   it, type DATE to the DOS prompt to make sure your own date is
   set correctly!


Naming Conventions for Distribution

I have abandoned a previous request that the program-and-manual
be in a separate file from the data.  It has proved to be too
confusing, and with inexpensive 14400-baud modems available, it
isn't burdensome to download everything at once.
                                                              1-8

So I recommend the distribution file name be either ZIPKEY, or
ZIPKEYym, where y is the last digit of the year of the data, and
m is the month of the data (1=Jan, ... , A=Oct B=Nov C=Dec).  The
extension of the file will, of course, reflect the compression
program used.

Examples: ZIPKEY45.ZIP will be the PKZIPped version containing
the 5/94 data.  ZIPKEY5C.ARJ will be the ARJ-compressed file
containing the 12/95 data.  If you prefer not to have version
information in file names, you can use just ZIPKEY.ZIP.


About the Author

I am a professional software author.  I have been programming for
myself since 1965, and professionally since 1975.  I worked for
Intel Corporation for several years, first as a subcontractor,
then as an employee, and then as an independent contractor.  I
have also done contract work for numerous other software firms.
In 1986 I started marketing programs directly to the public,
releasing my A86 assembler and D86 debugger packages as
shareware.  I have been making a living from shareware receipts
since 1987, supporting myself, my wife, and my daughter.

In the summer of 1988 I was persuaded by a friend that the world
needed a zipcode-directory and keyboard-enhancement program.  I
naively thought I could complete the program in about ten weeks.
At my level of experience I should have known better-- the first
release took about seven months of full-time work.  The resulting
product is much more powerful and elaborate than the original
vision.  The extra time spent also reflects the difference
between a software tool and a professional-quality software
product -- self-documentation, internal error detection for
"bullet-proof" operation, configurability to anticipate a wide
range of uses, and extensive testing in the field to enhance the
program's design as well as its reliability.

ZIPKEY has been a tremendous success, and now accounts for a
majority of my shareware income.  I will continue to update
ZIPKEY's database every month for the forseeable future.

CHAPTER 2   LOOKING UP ZIPCODES


In this chapter we'll explore all of ZIPKEY's search
capabilities, accessible from ZIPKEY's popup window.  As you read
along, you can execute the examples given from ZIPKEY's
demonstration mode, which pops up the ZIPKEY window without
placing ZIPKEY permanently resident in your computer's memory.
Occasionally I'll talk about what happens in the keystroke
playback sequence, which occurs in ZIPKEY's memory-resident mode.
Those features will show themselves after you've configured
ZIPKEY and then made the program resident in memory, as described
in Chapters 3 and 4.


Demonstration Mode

You can enter ZIPKEY's demonstration mode by selecting option 2
from ZIPKEY's main menu, or directly from the DOS command prompt
by typing

   ZIPKEY 2

followed by the Enter key.  If there is enough memory, ZIPKEY
will load the entire zipcode database into memory for the
demonstration.  If you are running ZIPKEY from a floppy disk,
this will take a few seconds (but the subsequent searches will be
breathtakingly fast if you're accustomed to floppy access speeds
for data lookup).  After the data is loaded, ZIPKEY's window will
pop up onto your screen, with the ZIPKEY signon message.  As long
as any ZIPKEY window is on the screen, it will tell you what
ZIPKEY expects you to be typing next, at or near the blinking
cursor.  Whenever the popup window is visible (whether in
demonstration mode or memory-resident mode), you can return to
the signon window by pressing the Home key, or you can pop away
the window by pressing the Esc key.

Whenever a zipcode specification is complete, ZIPKEY invites you
to confirm the entry by typing the Enter key.  In demonstration
mode, this will simply return you to the signon window, ready to
type another specification.  Later, when you make ZIPKEY
memory-resident, the confirming Enter will initiate the keystroke
playback sequence, in which ZIPKEY fools your computer (and
whatever program you are running) into thinking you have typed a
complete city/state/zip combination.


Signon Window

The signon window contains information establishing my copyright
and advertising my name and address.  It also tells whether you
are running the evaluation copy of the program or the registered
user's copy.  This information exists to remind you that ZIPKEY
is not in the public domain, and that I appreciate being paid for
my efforts.  But it doesn't waste your time-- you can start
typing your zipcode specification right away.

The blinking cursor appears just beyond the prompt indicating
each of the four types of zipcode search available to you:
                                                              2-2

1. If you type a digit (0 through 9), ZIPKEY treats it as the
   start of a zipcode to look up.

2. If you type a letter, ZIPKEY assumes you are typing a
   two-letter state abbreviation, to be followed by a city name.

3. If you type a question mark, you are signalling ZIPKEY that a
   city name without a state will follow.  For convenience, the
   unshifted / does the same thing.

4. If you type a left square bracket [, you are signalling ZIPKEY
   that a telephone area code will follow.  For convenience, the
   shifted { does the same thing.

There is a fifth specification type, not mentioned explicitly on
the window: the quote mark " to repeat the last zipcode.

We'll discuss each search type individually in the following
sections.


Zipcode Search

The zipcode search is simple: you type in a five-digit zipcode,
and ZIPKEY instantly tells you the associated city, if there is
one, with its state and area code.  If the zipcode isn't in the
directory, ZIPKEY will tell you and try to make a guess as to
what city it might be. You can either accept the guess with a
confirming Enter key, correct the entry with the backspace key,
or explore nearby zipcodes with the arrow keys (described
shortly).

ZIPKEY is so fast that it can afford to display intermediate
results as you type each digit of the zipcode.  Most people will
ignore these results when typing in most zipcodes-- they are
frills added to make ZIPKEY a little more convenient (and more
fun).

To demonstrate this, type the zipcode 47125, pausing after each
digit to see what ZIPKEY tells you.  After the first digit, you
get a lost of all the states whose zipcodes begin with 4.  After
the second digit, you get a list of the 10 possible 3-digit
regions beginnning with those 2 digits.  After 3 digits, ZIPKEY
lists the main city, area codes, and time zones for the region
selected.  After 4 digits, ZIPKEY lists the 10 possible 5-digit
zipcodes and their cities.  Finally, after 5 digits, you get all
the information ZIPKEY has for the zipcode given.

In demonstration mode, you can type either the Enter key or the
Home key to begin another search; the Esc key will exit the
program. Later, when you run ZIPKEY as a memory-resident program,
the Enter key acts as a confirmation of the zipcode given,
causing ZIPKEY to pop away the window and play the
city/state/zipcode combination through your keyboard.  The
guessed city will be used if the zipcode did not exist.  If you
don't want the guessed city to be used, you exit via the Esc key,
and type in the city/state/zip yourself.
                                                              2-3

The 2- and 3-digit display reflects the fact that zipcodes are
organized around three-digit regions: all non-local mail is
sorted according to region, and shipped to a main center for that
region.  Only when the mail reaches the regional center is it
sorted by the last two zipcode digits.  Most cities listed by
ZIPKEY are the postal service's regional centers for those three
digits, but many are not.  The exceptions are the regions
surrounding large cities, in which the cities themselves have
their own first-three digits.  The postal service considers the
large city to be the regional center; ZIPKEY will instead
typically give the name of a large suburb within that region.
For example, the postal service's regional center for 471 is
Louisville, KY, which handles the mail for nearby areas across
the Ohio River in Indiana.  ZIPKEY gives the main city for 471 as
Jeffersonville, IN, because it gives a better sense of where the
region is.

A handy feature of ZIPKEY is that it displays the current time in
the city you've looked up.  To do this, ZIPKEY must know the
timezone in which your computer resides.  This is specified when
you run the INSTALL program that comes on the ZIPKEY diskette.
If it isn't specified correctly, you can rerun INSTALL to get it
right.


Arrow and Paging Keys During Zipcode Search

To allow exploration of ZIPKEY's database, ZIPKEY allows you to
use the up-arrow, down-arrow, PgUp, and PgDn keys at any time
during the entry of a zipcode.  These keys either add or subtract
1 from the value already typed, letting you "move" through the
database.

The up-arrow key subtracts 1 from the digits typed (reflecting
the fact that if the zipcodes were listed in order on a page, the
zipcodes would decrease as you move physically up the page).  The
down-arrow key adds one to the digits typed.  For example, if you
type the single digit 0 to ZIPKEY's signon window, you'll get the
list of states whose zipcodes begin with 0.  You can now press
the down-arrow key repeatedly, to get the states lists for 1, 2,
3, etc.  You can go backwards by pressing the up-arrow key.
Likewise, you can type the two digits 00 to ZIPKEY's signon
window, then press down-arrow repeatedly to get successive lists
of main region cities.  The value will increment from 09 to 10,
so that the entire list of regions can be cycled through with 100
presses of the down-arrow key.  You get similar results after 3,
4 and 5 digits -- the 4-digit case is most useful, letting you
page through the individual cities in order.  Holding the
down-arrow key down for auto-repeat with 4 digits typed will give
you a sense of the sheer size of ZIPKEY's database, all packed
into your computer's memory.
                                                              2-4

The PgUp and PgDn keys don't provide any radically new
functionality over the up- and down-arrow keys: they simply work
because you might subconsciously think you are in a
word-processor, and expect them to work.  If you press PgUp or
PgDn after 1, 2, or 4 digits are pressed, you get exactly the
same action as the corresponding arrow key.  If you press PgUp or
PgDn after 3 or 5 digits are pressed, ZIPKEY will drop you back
to the 2- and 4-digit cases, respectively, to give you the
"paging" action you might have expected.  If you have configured
ZIPKEY not to display intermediate results (see Chapter 3 for how
to do this), the PgUp and PgDn keys will temporarily enable the
intermediate-results display.

Note that these "exploration" keys do not place you into any
special mode: when the typed zipcode increments or decrements, it
is just as if you had typed in the new digits in the first place,
and you can continue typing the zipcode from the new value.  For
example, any of the following keystroke sequences will get you
from the signon window to zipcode 12345:

   12345
   0{down}2345
   2{up}2345
   119{down}{down}{down}{down}45


State and City Search

Now we'll discuss the case in which you know the city and state,
and you want to look up the zipcode.  For this case, you start
from ZIPKEY's signon window, and type the two-letter abbreviation
for the desired state.  If you don't remember what the
abbreviation is, don't worry: just type the first letter of the
state's name, and you'll get a display of all the states, with
their abbreviations, that begin with that letter.

Your entry of either the state code or the city name can be in
either lower-case or upper-case: ZIPKEY doesn't care.  I give
them in upper case in the following paragraphs just to make them
easier for you to read.

After you type the two-letter state abbreviation, ZIPKEY prompts
you for the city name.  As you type the city, ZIPKEY will look up
all cities within that state that start with the letters you have
typed so far.  As soon as there are 50 or fewer matching cities
(usually after only one or two letters), ZIPKEY generates a
display of matching cities.
                                                              2-5

For example, suppose you need to know the zipcode for Robinson,
Illinois.  When you see the ZIPKEY signon window, you can type IL
for Illinois, followed by the city name.  There are more than 50
towns in Illinois whose name begins with R, so you don't get a
display if you type just R.  But after you type the second letter
O, a display is generated.  You may continue typing the city name
until there is only one city left.  Or, once there is a display
of cities, you can type a digit to select one of the cities on
the list.  In the database current to this writing, Robinson is
on the line numbered 3 in the RO display, so the complete
specification ILRO3 will select Robinson.  In the ROB display
Robinson moves up to number 2, so that ILROB2 would also select
Robinson.  Robinson is the only city in Illinois starting with
ROBI, so ILROBI would also select Robinson.

If there are more than ten cities in the generated display,
you'll see PgDn displayed off the end of the tenth city.  This is
your indication that the PgDn key will give you more cities.  If
you type PgDn once, you'll get the second ten cities that match
what you've typed so far.  A PgUp appears above the top right of
the cities list, to signal that you can now page back to the
first ten cities.  If there are still more cities beyond this
group of ten, the PgDn indicator will remain.  For example,
suppose you want to view all cities in Oregon whose name begins
with the letter B.  You type ORB to the ZIPKEY signon window,
followed by several PgDn keys to reveal several pages of Oregon
"B"-cities.


Multiple Zipcode Cities

If you perform a city search for a city having more than one
zipcode, ZIPKEY will give you the complete list of zipcodes for
that city, but it can't tell you which zipcode matches your
address -- that's beyond the scope of ZIPKEY's city-level data
base.  In this case, once the search has narrowed down to the
single city, ZIPKEY invites you to complete the zipcode with the
trailing digits it needs to resolve the multiple-zip ambiguity.
In ZIPKEY's demonstration mode, this will serve no purpose other
than to show you how the window will work in memory-resident
mode.  In memory-resident mode, the digits you type are needed to
provide the complete zipcode in the keystroke playback of
city/state/zip.  If you type a confirming Enter at a time that
ZIPKEY is prompting you to complete the digits of a zipcode,
ZIPKEY will fill out the zipcode with 0's, just as you might do
when addressing an envelope with a zipcode whose final digits you
don't know.
                                                              2-6

For example, suppose you wish to look up the zipcode for
Worcester, MA.  You type MAWORCES to the ZIPKEY signon window,
which is more than enough to narrow the display to the single
city.  Worcester has numerous different zipcodes, all beginning
with 016.  ZIPKEY places the blinking cursor after the common
digits 016, and invites you to complete the zipcode.  If you type
01, the prompt changes to a confirming Enter, and you'll get a
keystroke playback of 01601 as the zipcode.  If you type Enter
right away instead of 01, you'll get 01600 as the zipcode.  The
Postal Service will send your first-class later to region 016,
where it goes to a "don't know the zip" bin for special
processing.

A note about the list of zipcodes for a city: it consists of a
sequence of either individual zipcodes or zipcode ranges.  In a
zipcode range, the first and last zipcodes are always valid
zipcodes for the city displayed.  There will be no zipcodes in
the range that represent a city different than the one displayed.
However, there may be zipcodes within the range that are
undefined.  For example, in the database current at this writing,
the range 01613-55 for Worcester, MA represents a range running
from 01613 to 01655.  You can view the range in detail if you
switch back to zipcode lookup: type Home to return you to
ZIPKEY's signon window, then type 0161 followed by four presses
of the down-arrow key.  You'll see that there aren't any
non-Worcesters between 01613 and 01655, but that most of the
range is undefined.


City-Only Search

ZIPKEY also allows you to search for a city name without
specifying the state.  To use this feature, you type a question
mark to the ZIPKEY signon window.  ZIPKEY will prompt for the
city name, and tell you to press the Enter key when you want the
search to begin.  This search requires ZIPKEY to walk through the
entire zipcode database, which is too slow to display
intermediate results.  You may type either a partial name (the
first few characters), or a complete name.  When you press the
Enter key, ZIPKEY will change the state display to the first
state containing a matching city name, and list the matching
cities.

If there are no matching cities, ZIPKEY tells you, and invites
you to correct the entry with the backspace key.  Remember, you
don't have to type the whole city name-- the first few letters
may narrow the possibilities enough for you to find your city
without risking a misspelling.
                                                              2-7

Let's do a sample city-only search.  There's a commercial on TV
in which a woman tells how they prepare Shredded Wheat back home
in Nome.  A co-worker replies, "I didn't know you were from
Alaska.", to which the woman replies, "I'm not; I'm from Nome,
Texas."  As a vigilant ZIPKEY user, you wish to know if there are
any other Nomes out there.  You type ?NOME followed by the Enter
key to the ZIPKEY signon window.  ZIPKEY displays the first
state, Alaska, containing a Nome.  Now read on to the next
section to see how to get the other Nomes.


Moving From State to State

The city-only search just described will give you just the first
state containing a matching city.  To move on to subsequent
states, you press the down-arrow key.  So, from our previous
example, when you have Nome, Alaska selected, you press the
down-arrow key to find the next state containing a matching city.
ZIPKEY reveals a hitherto-unrevealed Nome, in North Dakota.
Pressing down-arrow again moves the display to the Nome, Texas of
the Shredded-Wheat woman.  Another down-arrow cycles us back to
Alaska, so we conclude that there are exactly three Nomes in the
database.

What happens when there is a state containing a matching city,
but that is the only such state?  If you press down-arrow, ZIPKEY
will take several seconds to try to find another state, then
return to the same display.  You can tell that the search is
complete because the blinking cursor goes to the state code
during the search, then returns to the city name when the search
is over.

Again, I've tried to minimize the number of special modes in
which you can be.  When you perform a city-only search, and reach
the first state, it is just as if you had typed that state's code
instead of ? in the first place.  Conversely, if you type a
state-and-city specification, you can move to other states with
that same city specification by pressing the down-arrow key to
move to the next state; or the up-arrow key to move to the
previous state containing a matching city.
                                                              2-8

Unabbreviation

For consistency and completeness, ZIPKEY's data base stores all
city names in a totally unabbreviated form, spelling out words
such as Saint, Sainte, Fort, Mount, North, South, East, and West.
(The one exception is the word "National" in cities containing
the phrase "National Park", which is stored as "Ntl".  I wanted
to minimize the number of excessively long city names.)  The
unabbreviated forms will not cause a problem for you if you need
to fit your city name into a fixed field, because ZIPKEY does a
good job of abbreviating names as necessary to fit in such fields
(details are in Chapter 3).  But you might forget to spell out a
name such as St. Louis when typing a city specification that you
would like ZIPKEY to search.  So ZIPKEY allows the abbreviations
St, Ste, Ft, Mt, N, S, E, and W for the above-mentioned full
names.  The abbreviations must be followed by a period or a space
for ZIPKEY to accept them.

For example, suppose you type MNST to the ZIPKEY signon window.
You'll get a list of Minnesota cities beginning with ST, and none
with Saint.  But if you now type a period or space, ZIPKEY will
switch to a list of Saint cities.


Telephone Area Code Search

You may use ZIPKEY to find out what geographical area is
associated with a given telephone area code.  Simply type a left
square bracket [ followed by a three-digit area code.  If an area
code is the only code for its state, you'll be told the name of
that state.  If there are other area codes within the state,
ZIPKEY will give a list of sample cities, to give you an idea of
what part of the state your area code covers.

Note that for APO/FPO and Pacific territories, ZIPKEY returns an
"area code" of 011 -- that's actually the direct-dial access code
for overseas. Since 011 is not a true area code, the [ search
doesn't recognize 011: I didn't think it was worth the special
coding necessary.


Repeat Last Zipcode

Finally, we cover a fifth specification that can be typed from
ZIPKEY's signon window-- a double-quotes mark " to call up the
last zipcode returned.  This option exists to accommodate hotkeys
that repeat the last zipcode specified, and also hotkeys that
play back a keystroke sequence unrelated to any zipcode.  These
possibilities are covered, with examples, in Chapter 3, in the
fixed-keystrokes option of the Zipcode Source section.
                                                              2-9

Typing the quotes mark " causes ZIPKEY to display the previous
zipcode, city, and state found, and immediately prompt for the
confirming Enter key.  The "previous" zipcode specification
starts out nonsense (Aaron, AL 00000 in the current database at
this writing) until a real zipcode is looked up.  The "previous"
specification does not change if a lookup is cancelled via Home
or Esc -- it changes only after the confirming Enter or alternate
exit key is pressed.

CHAPTER 3   ZIPKEY CONFIGURATION


In this chapter we discuss how you can tailor ZIPKEY to your
specific needs.  You can choose where the zipcodes are stored
when ZIPKEY is loaded into your computer's memory, which keys you
will press to invoke ZIPKEY, the location and color of the ZIPKEY
popup window, and the format for the city/state/zip combination
to be played back though your keyboard.

These adjustable selections for ZIPKEY are stored in a special
file on your disk, called a ZC (for ZIPKEY Configuration) file.
Every time ZIPKEY is placed resident in your computer's memory, a
ZC file is automatically read, to determine all of the
configuration choices you made.


Determining Your Configuration Needs

Before you attempt to create a ZC file, you should spend a little
time exploring how you are currently typing in addresses.  In
order to let ZIPKEY fool the computer into thinking you have
typed in a complete city/state/zip, you'll have to tell ZIPKEY
exactly what you type-- this can include preliminary positioning
keystrokes, intervening keystrokes for punctuation, spacing, or
further positioning, and trailing keystrokes for termination or
still more positioning.

For example, suppose that you use two different programs to enter
addresses: a database management program and a word processor.
Before you try to configure ZIPKEY, you should invoke each
program and type in a sample address.  You enter the database
manager, which puts an address template onto the screen.  You
type in a name and an address, noticing that you use the Enter
key to move from field to field.  You press the Enter key to
reach the start of the city field.  At this point, you should
count the number of available spaces in the city field.  If this
is visually difficult, the sample name you type can assist you:
type Xxxx xxxx xxxx xxxx etc. to mark spaces.  Let's suppose
there are 17 spaces available.  Make a note of this number:
ZIPKEY will need it.  You press the Enter key to advance the
cursor to the two-letter state abbreviation field.  You type a
sample two-letter state code, and notice that the cursor
automatically advances to the zipcode field without your typing
Enter -- such a detail is important for the accurate recording of
the keystroke sequence.  Then you type the five-digit zipcode and
notice that another Enter is required to advance the cursor to
the telephone field. Finally, you type the area code, a minus
sign (hyphen), and the telephone number.  So the exact keystroke
sequence for getting from the last field before the city to the
hyphen after the area code is:

{Enter}C{Enter}AZ{Enter}T-

where the variable parts of the entry are denoted by the letters
C,A,Z,T.  Again, the lack of an {Enter} between A and Z reflects
the fact that the cursor moves automatically from the state
abbreviation to the zipcode field.
                                                              3-2

Now you discard the sample record you have created, exit your
database manager, and invoke your word processor.  You use this
program to type letters: addresses are typed in as a letterhead.
The format consists of the city name, a comma, a space, the
two-letter state abbreviation, a space, the zipcode, and two
Enter keys.  In our notation, this is

C, A Z{Enter}{Enter}

with no limitation to the length of the city name.  You have now
gathered the information needed for a ZIPKEY specification.  You
can exit your word processor and invoke ZIPKEY's configuration
option, described in the next section.


How to Create a ZC File

You create a ZC file by selecting ZIPKEY main menu option 3,
"Configure ZIPKEY for memory-resident use".  You may also go
directly to this option from DOS's command prompt, by typing
ZIPKEY 3 followed by the Enter key.  If you've never configured
ZIPKEY before, you will immediately be given the configuration
questionnaire, as described in the following sections.  If you
have already configured ZIPKEY, you will be given the
configuration editing menu.  You can repeat the entire
configuration by choosing option 1, "Replace entire
configuration."


Default Options

The following sections describe each configuration option you'll
encounter.  Before we begin each option, however, let's discuss a
feature that covers the entire ZIPKEY configuration process: the
default option.

In most situations during ZIPKEY configuration, ZIPKEY attempts
to discern what option it thinks you are most likely to select.
It will display that option underneath the current cursor
position as it waits for your response.  If you wish to select
this default option, you may do so explicitly by retyping the
already-displayed selection.  But you can also select the default
option by simply pressing the Enter key.

If you are respecifying a previously-existing configuration, the
default options will be those from the old file.  You can press
Enter for those sections that you don't want to change.  If you
are configuring for the first time, the default is the option
that I think most people will choose.  If you are confused by an
option and aren't sure what to select, press Enter to get the
default setting.

Memory Model

ZIPKEY consists of two parts: the ZIPKEY program that controls
ZIPKEY's functions, and the database that contains the zipcodes
themselves.  When you make ZIPKEY resident, the program always
goes into your main computer memory -- it occupies about 22000
bytes (22K of the 640K available in most late-model computers).
Unless you use an outside utility such as LOADHI, you don't have
any choice as to where the ZIPKEY program is stored.  However,
you do have a choice as to where the database (occupying about
128K) is stored:

1. You may have the database stored in Lotus-Intel-Microsoft
   expanded (EMS) memory.  This is a special kind of memory,
   provided by add-on boards such as Intel's AboveBoard, designed
   to break the 640K memory capacity "barrier" of the IBM-PC
   family.

   If you're not sure whether your system has EMS memory, don't
   worry: ZIPKEY determines this for you, and makes this option
   the default if there is sufficient EMS memory available to
   load the database.

   If this option is available to you, it is usually the best.
   It allows the fastest access to the database without occupying
   main memory, and it avoids any potential problems resulting
   from attempting to access the disk from a popup utility.

2. You may keep the database on your disk, causing ZIPKEY to
   access the database file every time it looks up a zipcode.
   This option is slower than the other two options, but not too
   slow: only two disk read operations (maximum 400 bytes and
   usually much less) are required to look up each zipcode entry.
   On a hard disk this takes a small fraction of a second.

3. You may load the database into main memory.  This allows the
   same fast access as the EMS option (maybe even a shade
   faster), but it means that every other program running on your
   computer will have 128K bytes less memory to work with.  There
   are many situations in which this won't be a problem: for
   example, if the computer is dedicated as a workstation for
   order entry, you can experiment to see if it works just as
   well with ZIPKEY's data stored in main memory.  If it does,
   fine: you get the fastest access without having to buy an EMS
   memory board.

There is an additional question if you did not choose to keep the
data on the disk (you chose EMS or main memory instead).  ZIPKEY
asks if you will be running Desqview after making ZIPKEY
resident.  This option will force ZIPKEY to make an additional
compatibility check before popping up its window (the check is
made anyway if the data comes from the disk).  Even if you don't
run Desqview, if you have problems with ZIPKEY in EMS or
main-memory mode, but not in disk-mode, you should try answering
Y to this question.
                                                              3-4

Intermediate Results

As an added convenience (and also for fun!) ZIPKEY is capable of
displaying what it knows about the specification you have typed
so far.  For example, if you have typed in exactly 4 of the 5
digits of a zipcode, ZIPKEY will display a list of the 10
possibilities for the fifth digit.  If you type a partial
specification and then use the up-arrow, down-arrow, PgUp, and
PgDn keys, you can "explore" the database.

There are two reasons why you might want to suppress the display
of intermediate results: first, to avoid the time it takes to
look them up.  If you are getting the zipcode data from a slow
disk, or you are running on an older slow (4.77 MHz) computer,
then the results are likely to lag a bit behind your typing.  The
lag is typically no more than about a second-- it's a matter of
taste whether this is acceptable to you.  The second reason for
suppressing intermediate results is purely a matter of taste: you
might be visually annoyed by all that unused information flashing
past as you type.  If that is the case, however, you may wish to
choose the option (described later) of taking zipcodes from the
screen -- that way you can arrange for ZIPKEY's window not to pop
up at all, which absolutely minimizes the visual distraction.


Slow Down Keyboard

This option insures that ZIPKEY doesn't provide keystrokes too
fast for your program to successfully digest.  To be on the
conservative side, you should select Y for this option when you
configure ZIPKEY for the first time.  Then, after you have ZIPKEY
working, you can try changing this option to N, so that the
entire city/state/zip combination appears instantaneously in your
program.

Two programs that definitely need Y are the Condor database
system, and older versions of the Wordstar word processor.

If you select N when you needed Y, you'll see missing keystrokes
in the playback of city/state/zip.  The problem exists in some
modern programs, but it is most common in older programs.  The
problem was made widespread when Borland, in its Turbo Pascal
version 2, published a recommended procedure for programs to
fetch keystrokes from the computer.  The procedure involved
fetching each keystroke two or three times, relying on the fact
that no human could type the next key before such multiple
fetches were made.  This programming method did not foresee the
advent of keyboard enhancement programs such as SmartKey, ProKey,
and now ZIPKEY, that simulate keyboard typing at computer speeds.
                                                              3-5

Window Characteristics

This section of ZIPKEY's configuration allows you to adjust the
visual characteristics of ZIPKEY's popup window.

ZIPKEY tries to present you with a window that is both easily
noticed and unobtrusive.  To be easily noticed, ZIPKEY pops a
window with a different color than the underlying screen (reverse
video for monochrome monitors).  To be unobtrusive, ZIPKEY avoids
popping up in a location that would cover up the current cursor
location on the screen.

For windows configuration, ZIPKEY simultaneously pops up two
windows.  The main window shows where ZIPKEY usually pops up.
The alternate window shows where ZIPKEY pops up if the main
window would cover the current cursor position.   You can
eliminate the alternate window (thus disabling the cursor-dodging
feature) by pressing the F5 key, which toggles the alternate
window on and off.  You'll need to disable the alternate window
if you want the main window to pop up in the middle of the
screen, where there isn't room on either side for an alternate
window.  You can swap the main and alternate windows by pressing
the F6 key.

During this configuration window display, you can use the arrow
keys (Up, Down, Left, or Right) to move the main window.  You
cannot move the alternate window directly, but you can
temporarily swap the main and alternate windows with F6, move the
temporarily-main window, and then reswap with F6 again.

The remaining function keys are used to adjust the colors for the
popup window.  The internal numeric codes for the colors are
displayed, so that you can manually record the settings if you
wish.  There are two function keys for each setting: one to
decrement the numeric code, the other to increment the code.  F1
and F2 change the window color (sometimes called the "background"
color) usually displayed.  F3 and F4 change the text
("foreground") color.  If most of the underlying screen (actually
a diagonal sample of cells, to save time) is the same background
color as the window's main color, then ZIPKEY uses the alternate
color, displayed on only four lines of the main configuration
window.  The alternate window color is adjusted by F7 and F8; the
text color by F9 and F10.

When you have completed adjusting the windows to your taste, you
press the Enter key to pop away the configuration windows, and
move on to the next stage of configuration.
                                                              3-6

Monochrome and Color Window Settings

If you are installing ZIPKEY on multiple computers, some with
monochrome screens and others with color screens, then you should
create your ZC file on one type of screen, and modify it for
window colors on another computer with the other type of screen.
ZIPKEY stores separate color codes for monochrome and color
screens.  When it is run, ZIPKEY detects whether you have color
or monochrome.  If you have a color screen, ZIPKEY uses the
selections you configured on a color screen; if you have a
monochrome screen, ZIPKEY uses the other selections you made on
monochrome.  Thus, you don't need to have a different ZC file for
your monochrome vs. color computers.


Hotkey Configuration

All of the options described up to now are general settings--
they determine the overall characteristics of ZIPKEY, that don't
depend on which hotkey was pressed to invoke ZIPKEY.  Now we'll
discuss the characteristics specific to hotkeys -- they change
depending on the keystroke combination used to invoke ZIPKEY.

We recall the example spelled out in the section "Determining
Your Configuration Needs" earlier in this chapter.  In that
example, you will invoke ZIPKEY in two different contexts: from
within a database manager, and also from within a word processor.
The format for typing city/state/zipcode differs in the two
contexts.  In the following sections, we'll present one method of
handling the difference: we'll define two different hotkey
combinations to invoke ZIPKEY.  One hotkey is to be used while in
the database manager, and the other hotkey is to be used while in
the word processor.  Later, we'll talk about other ways to handle
the difference (with alternate exit keys, or with alternate named
ZC files).


Hotkey Name

The first part of a hotkey specification is its name-- the
combination of keystrokes you will use to invoke ZIPKEY.  To
detect hotkeys, ZIPKEY monitors the signals coming directly from
the keyboard into your computer, so that ZIPKEY can tell when you
have pressed keys simultaneously.  You should select some
combination of keys that won't be pressed for any purpose other
than invoking ZIPKEY.  Often you won't need a combination: you
might find some individual keys on your keyboard that are
otherwise unused.  Here are some ideas for hotkeys you can use:

1. You can use the 5 key on the numeric keypad.  Of course, you
   should only choose this if you habitually keep Numlock off.
   Otherwise, you wouldn't be able to use the keypad to type any
   numbers containing the digit 5.

2. Other individual keys that are seldom used are the F11 and F12
   keys on the newer-generation keyboards, and the SysReq key on
   the AT keyboard.
                                                              3-7

3. If the computer using ZIPKEY is dedicated to a single purpose,
   such as order entry, you might have a printing key on your
   keyboard, such as the back-quote key, that is almost never
   used.  You can make this key a ZIPKEY hotkey without causing
   too much inconvenience.  If you do so, you may wish to define
   Alt-backquote as a special hotkey that produces a back-quote
   (how to do this is discussed later).

4. Exotic combinations of the shifting keys (Shift, Ctrl, Alt),
   possibly combined with a single non-shifting key, are often
   used as hotkeys to invoke memory-resident programs.  Examples:
   Ctrl-RightShift, both Shift keys, Ctrl-Shift-Z, or both Shift
   keys and Z.  A couple of cautions are in order here: First, if
   there are other memory-resident programs residing
   simultaneously with ZIPKEY, you must insure that every
   programs' hotkeys can be detected by that program.  For
   example, Ctrl-Alt-Z wouldn't be a good ZIPKEY hotkey if you
   have Sidekick, because Sidekick would pop in when it saw the
   Ctrl-Alt.  Second, you should be aware that ZIPKEY
   distinguishes between left and right shifting keys.  If you
   don't want ZIPKEY to distinguish, you can define identical
   hotkeys with each combination.

5. If you've used up all the obvious sequences, ZIPKEY allows
   combinations not usually seen in hotkeys; namely, you can have
   more than one non-shifting key.  A mnemonic choice would be
   the Z and C keys pressed simultaneously-- they're close
   together but not adjacent so the combination won't be pressed
   accidentally.  This hotkey requires an extra consideration:
   from the computer's point of view, the keys will never be
   simultaneous: one code will always be received before the
   other.  ZIPKEY doesn't care which key comes first, as long as
   the second key is pressed before the first one is released.
   But before ZIPKEY can pop up, one of the two keycodes will be
   seen by the program (e.g. the database manager or word
   processor) that you're running.  So an unwanted Z or C will be
   displayed. You handle this in your returned city/state/zip
   keystroke sequence, by specifying the first returned keystroke
   to be the backspace key, wiping out the Z or C.

   Another caution is in order for the most exotic sequences:
   some keyboards get confused by more than two non-shifting keys
   pressed simultaneously, and don't deliver all the codes to the
   computer for ZIPKEY to see. ZIPKEY lets you verify that your
   sequence is being received correctly, by echoing the sequence
   for confirmation.  You can experiment with various
   combinations to see what works, before confirming the name for
   your hotkey.

The echoing of your hotkey is based on the internal codes
delivered by the IBM-PC and 100%-compatible keyboards.   Most
keyboards are compatible with the IBM-PC, but some aren't.  For
those keyboards, the echoed names won't match the names of the
keys as you know them.  However, as long as the echoing is
consistent (you get the same thing on several tries), the hotkey
will work correctly when you use ZIPKEY.
                                                              3-8

Recalling our database/word processing example: let's assume you
have a newer-generation keyboard with F11 and F12 keys.  You'll
use F11 for the database hotkey and F12 for the word processing
hotkey.  So the first time you are prompted for a hotkey name,
type the F11 key for the name, and Y to confirm the name.


Zipcode Source

Once you have confirmed the name of a hotkey, ZIPKEY next asks
for the first action it should take when you have pressed the
hotkey.  There are four choices: first, ZIPKEY can simply pop up
its window and wait for the operator to type a zipcode
specification.  Second, ZIPKEY can look at the contents of the
video display, to find a zipcode that already appears on the
screen.  Third, ZIPKEY can pretend that it has popped up its
window and that a fixed sequence of zipcode specification
keystrokes has already been typed. Finally, ZIPKEY can look at
the last 16 keystrokes typed, and use the last 5 digits typed as
the zipcode to be searched.  Let's consider each choice in turn:

1. The popup-window option is the simplest and most
   commonly-used.  There are no further configuration choices you
   need to make for this option.

2. The video screen option is used when the zipcode has already
   been typed at the time ZIPKEY is invoked.  You can use this
   option to create a hotkey that verifies existing address
   records, or to create a data-entry scenario in which ZIPKEY's
   window normally doesn't pop up at all, and so is the most
   unobtrusive.

   If you choose to take the zipcode from the video screen,
   ZIPKEY will look for five consecutive digits on the same line
   as the cursor, or on an immediately adjacent line, above or
   below the current line.  If no five-digit sequence is seen,
   ZIPKEY will pop up a window just as if option 1 had been
   selected.  If a five-digit sequence is seen but it isn't a
   valid zipcode, ZIPKEY will pop up its window with that
   zipcode, and tell you that the city wasn't found.  For the
   final possibility, a valid five-digit zipcode, you have an
   option: you can have ZIPKEY pop up its window so that you can
   confirm the city, or you can have ZIPKEY automatically play
   back the city/state/zip sequence without popping up at all.
   If you want to allow the possibility of using alternate exit
   keys (described later), you must choose to have ZIPKEY always
   pop up the window.

   What happens if there is more than one five-digit sequence on
   the screen? ZIPKEY uses the first sequence it finds, searching
   in the following order: first, it starts five characters
   beyond the current cursor position, looking backwards to the
   start of the current line.  Then it looks from the current
   cursor position forwards to the end of the current line.  Then
   it looks backwards from the end to the start of the line above
   the current cursor position.  Finally, it looks from the start
   to the end of the line below the current cursor position.
                                                              3-9

3. The fixed-keystroke option is used for a number of
   special-purpose applications.  For example, if a large number
   of addresses that you type are in a local area in which the
   first three zipcode digits are always the same, you may wish
   to define a hotkey with a fixed-keystroke sequence consisting
   of those three digits.  Or, if your data-entry scenario
   includes typing the zipcode twice (as a part of an ID number,
   then later as a part of the address), you may wish to define
   an option 1 (popup) hotkey for the first instance of the
   zipcode, then another, option 3 hotkey for the second
   instance, with a fixed-keystroke string of "{Enter} to repeat
   the zipcode.  Finally, you can use this option to make hotkeys
   to generate keystroke sequences having nothing to do with
   zipcodes.  To do this, you again use "{Enter} as the fixed
   input sequence, so that the ZIPKEY window doesn't pop up.
   Then you specify a playback sequence that doesn't use any of
   the zipcode entries -- I'll give an example at the end of this
   chapter.

                                                             3-10

   When you choose this option, ZIPKEY prompts you for the fixed
   keystroke sequence.  Remember, this is a sequence of keys that
   you could have typed if ZIPKEY's window had popped up.  Thus,
   it should follow ZIPKEY's popup syntax: either a sequence of
   digits for a zipcode, or a two-letter state code followed
   optionally by a (partial or complete) city name, or a
   question-mark followed by a city name, or the double-quotes
   mark " to repeat the last zipcode.

   Note that the Enter key can be included in the keystroke
   sequence.  Thus you must use another key to tell ZIPKEY right
   now that you've finished typing the keystroke sequence.  I
   have chosen the * character as the signal for this, as it
   isn't a part of ZIPKEY's popup syntax.

   A common mistake is to confuse this fixed keystroke sequence
   with the sequence of keys intended to be played back through
   your keyboard.  If, for example, you provide Bloomington, IN
   47401* here, ZIPKEY will pretend you had typed BLOO etc. when
   its window popped up. ZIPKEY is forgiving about BL not being a
   proper state code, and will switch to a city-only search for
   the string given.  However, the comma and all the follows will
   be part of the city name being searched, so the search will
   fail.  You should instead provide the simpler fixed sequence
   47401{Enter}* and give a playback sequence (described shortly)
   that causes the desired fixed city/state/zip combination.

4. The last-keystrokes option is the only one you can use if you
   wish to type in zipcodes from within graphics programs such as
   Borland Reflex or Ventura Desktop Publisher.  ZIPKEY cannot
   pop up when your video display is in graphics mode; nor can it
   read the contents of the screen.  With this option, you type
   the zipcode first, before pressing the ZIPKEY hotkey.  ZIPKEY
   can replace the zipcode typed with the city/state/zip, without
   the window ever needing to pop up.  If the zipcode isn't
   already placed correctly when it is typed, you need to begin
   your playback sequence with bbbbb to wipe out the zipcode.

In the database management example, you'll choose option 1, to
pop up a window and wait for the operator to type in the zipcode.


Format of City/State/Zip Keystrokes

In normal ZIPKEY usage, after the zipcode has been specified and
the Enter key is typed to confirm the city found, ZIPKEY will
fool the computer into thinking a complete city/state/zip
combination has been typed.  You specify the format for this
combination now, during the specification of your hotkey.

The sequence usually consists of variable parts (city, state,
zip, area code, time zone) that depend on the zipcode, combined
with fixed parts: the keystrokes that separate the variable
parts, such as spaces, punctuation marks, and positioning keys.
As you specify the sequence, you type most of the fixed parts
(spaces, commas, Enter, Tab, arrow keys, etc.) just as you want
them played back.  For each variable part, you substitute a
letter (which you can type in either upper- or lower-case) from
the following list:
                                                             3-11

C  causes the name of the city to be generated.  ZIPKEY will
   abbreviate the name as necessary to fit it into a fixed-sized
   field.  When you type the C now at configuration time, a
   window pops up, prompting you to follow the C with the
   two-digit width you would like the city to fit into. You
   should type 99 if there is no limit.  A limit of 15 will give
   you reasonable results in all cases.  A limit less than 15
   will make some entries undecipherable and/or ambiguous.  A
   limit of 19 will cause all but a few cities not to be
   abbreviated at all.  The longest city name in the database is
   King and Queen Court House (Virginia), which has 26
   characters.

   If you type a limit less than 99, ZIPKEY will then ask you to
   specify whether the playback should follow the city name with
   a sequence of spaces (or right-arrows, or whatever) to fill
   out the fixed field.  Most database managers (including the
   one in our example) won't require this -- they let you type a
   single key, such as Enter or Tab, to advance to the next
   field. You would typically need this padding only if you are
   using a simple text editor to maintain a fixed-field database.
   If you need the padding, type F followed by the padding
   character (typically the space bar).  If you don't need the
   padding, type N and continue the playback sequence by
   providing the character needed (Enter, Tab, etc.) to advance
   beyond the city field.

A  causes the two-letter state abbreviation (in capital letters)
   to be generated.

Z  causes the five-digit zipcode to be generated.  There is one
   case -- a city search which returned multiple zipcodes in
   which the operator didn't complete the zipcode -- that 0's are
   provided to complete the zipcode.

T  causes the three-digit telephone area code to be generated.

H  causes a two-digit number indicating the time zone to be
   generated.  The number represents the number of hours beyond
   the Internation Date Line: 04 for Pacific, 07 for Eastern,
   etc.

D  causes a single keystroke to be generated, that indicates
   whether the city observes daylight savings time in the summer.
   You follow the D with two keystrokes: the one you want output
   if it is observed, followed by the one you want output if it
   isn't.  For example, DYN will output a Y if it is, an N if it
   isn't.

In addition to the above commonly-used letters, ZIPKEY offers the
following letters for more special purposes:
                                                             3-12

B  causes a backspace to be generated.  This is on this list so
   you can use the backspace key right now to correct your
   configuration entry.  You will begin your playback sequence
   with B if the hotkey name was something like Z C, which causes
   one letter to escape to the application program.  You can also
   begin the playback sequence with BBBBB if you used option 2 or
   option 4 above to read a just-typed zipcode, and you wish to
   replace the zip with city/state/zip in the playback sequence.

L  causes the next character to be literalized -- that is, it is
   output as-is even though it might be on this list.  You can
   and should literalize all letters played back, just in case
   future versions of ZIPKEY add new letters to this list.  You
   can also literalize the * character to cause it to be played
   back instead of being interpreted as the terminator to this
   sequence.  For example, you may wish to embellish our
   word-processing example by appending LDLeLaLr followed by a
   space to the playback, causing "Dear " to be generated below
   the letterhead.

R  is used to retreat back across a variable-length city name.
   This would be used in a special case in which an address is
   being generated that might be indented on the page by an
   unknown amount.  Some text editors might require you to
   left-arrow back to the start of the name, then down-arrow to
   the next line to be aligned with the city-line.  You follow
   the R with the left-arrow key, or whatever other key you wish
   to be repeated by the length of the city name.

S  causes the full name of the state to be generated.  Most
   people will not use S, but instead use A to generate the
   two-letter abbreviation.

W  causes the computer to wait until the next 1/18th-second timer
   tick before generating the next keystroke.  This is an
   alternative to the keyboard slowdown option.  Some
   applications require an extra-slow playback at one particular
   point -- perhaps at the beginning, or at some point at which
   the program switches screens or accesses your disk. At those
   points, you may need to insert one or more W's into the
   playback sequence.

Just as with the fixed input specification, you can include the
Enter key as part of the sequence of keystrokes.  So you signal
ZIPKEY that the sequence is complete with the * character.

Returning to our database example, recall that the keystroke
sequence used for entering the city/state/zip/areacode
combination was

{Enter}C{Enter}AZ{Enter}T-
                                                             3-13

This is what you should type when ZIPKEY asks for the keystroke
playback sequence.  When you type C, ZIPKEY asks for the maximum
city width-- you should give the field width 17.  Then ZIPKEY
tells you to type F if you need padding, and N if you don't.  You
don't need padding, so you type N.  The complete specification
you type, including the terminating *, is

{Enter}C17N{Enter}AZ{Enter}T-*


Multiple Hotkeys

As a more advanced option, ZIPKEY allows you to define multiple
hotkeys.  (The limit is 99, which I hope is much more than anyone
will ever need.)  When you are setting up a new configuration
file, ZIPKEY will invite you to define another hotkey after the
first hotkey specification is complete.  You may also add hotkeys
at any point later in time, by selecting the appropriate option
in the configuration editing menu.

In our example, you answer Y to the invitation to define another
hotkey, and name the second hotkey F12.  You again choose zipcode
source option 1, to pop up the window and wait for keyboard
input.  The keystroke return sequence for word processing,
including the 99 for unlimited width and the terminating *, is

C99, A Z{Enter}{Enter}*


Exit Keys

Here is another option for more advanced users.  We've just seen
that one way to specify different keystroke playback sequences is
to define a different hotkey for each sequence.  Another way is
to define one or more alternate ZIPKEY exit keys.

The normal method for confirming a zipcode and initiating key
playback is the Enter key.  If you have defined an alternate exit
key, you can press that alternate key instead of Enter to confirm
a zipcode.  The keystroke playback sequence is associated with
the exit key, and so remains the same no matter what hotkey was
used to invoke ZIPKEY.
                                                             3-14

Since the function keys (F1, F2, etc.) have no other meaning at
the moment you are about to exit the ZIPKEY window, they are good
choices for alternate exit keys.  Let's consider our
database-and-word processing example.  Suppose you don't have a
new-generation keyboard with F11 and F12 keys, and you don't like
exotic keystroke combinations.  So you wish to define only one
hotkey, numeric 5.  You decide that most addresses will be typed
in through the database manager, so you specify the database
return sequence {Enter}C17N{Enter}AZ{Enter}T-* for the hotkey.
It will be played back whenever the Enter key is used to confirm
a zipcode.  For word processing, you define an alternate exit key
F1, and specify the word-processing sequence C99,  A
Z{Enter}{Enter}* as the playback sequence for F1.  Then, whenever
an address is being typed to the word processor, it is confirmed
with F1 instead of Enter, to get the alternate playback.

You can, of course, have both multiple hotkeys and alternate exit
keys. This would be desirable, for example, if you wanted to have
a number of different input combinations (e.g. popup a window
immediately, take the zipcode from the screen, and several
different fixed keystroke combinations for different localities),
combined with a number of different playback sequences.  You
would define a different hotkey for each input possibility, and
an alternate exit key for each playback sequence (except the most
commonly-used sequence, which you specify for every hotkey as the
sequence used when Enter is pressed to confirm an entry).

Another usage of exit keys is to handle exceptional cases of
address entry. Two examples come to mind.  First, you may wish to
define an exit key for cases in which ZIPKEY's city doesn't match
the city you wish to type. Alas, the existence of zipcodes
covering two cities makes this a possibility. You can define a
key sequence that fills in everything except the city, and leaves
your cursor at the city field ready for entry.  That way you're
still saving keystrokes having used ZIPKEY.  Second, you could
define an exit key that facilitates the entry of 9-digit (ZIP+4)
codes.  ZIPKEY doesn't have any information about 9-digit
zipcodes-- that database would occupy over 25 megabytes, even
with ZIPKEY's rate of compression.  But you can define an exit
key to handle 9-digit address entry, by specifying a key sequence
that outputs a hyphen after the zipcode, and leaves the cursor
positioned after that hyphen.  Then you can type the first 5
digits to ZIPKEY, and the final 4 digits after the window pops
away.  In the coming years, when 9-digit zips appear in the
majority of addresses, you can make this sequence the main hotkey
sequence, and the 5-digit case a special exit key sequence.
                                                             3-15

Configuration Editing Menu

After your configuration specification is complete, ZIPKEY goes
to the configuration editing menu.  This menu allows you to
display and/or modify the configuration choices you have made.
There are the general options (memory, intermediate results, slow
keyboard, and all the window settings), the hotkey names, and the
exit key names and playback sequences.  Again, the default values
for the general options are the values you chose before -- if you
wish to change just a single option, choose "General options" and
then just keep pressing Enter until that setting comes up.

Option 6 of the configuration menu allows you to generate your
own quick reference card. I do not provide a printed
quick-reference card as a part of the ZIPKEY software package,
because much of the useful information contained on that card is
specific to your configuration.  Instead, this option prepares a
quick-reference document containing the configuration
information, that you can print out yourself.  The file is
written as ZIPKEY.ZQR (ZQR stands for Zipkey Quick Reference) on
your current disk directory.  You may wish to edit the document
for formatting before printing it; or you can simply type to the
DOS prompt the command COPY ZIPKEY.ZQR PRN.


Named Configuration Files

The final action in the configuration process is to save the ZC
(Zipkey Configuration) file to your disk, so that ZIPKEY can read
it every time you make ZIPKEY resident in memory.  If you will
have only one configuration, you should use the default file
name, ZIPKEY.ZC.

You may, however, wish to have different configurations, either
for different users or for different computing contexts.  In our
example, this would be a third way to provide a different
playback sequence for the database manager vs. word processor
case.  You could configure a single hotkey for the database, and
name its ZC file DATA.ZC.  Then you could make another
configuration, named WORD.ZC, with a single hotkey for the word
processor. Before entering the database manager, you always load
ZIPKEY using DATA.ZC; before entering the word processor, you
load ZIPKEY using WORD.ZC.

When ZIPKEY asks you for the name of the configuration file, you
do not need to type the file-name extension .ZC, but you can if
you want.  Any extension other than .ZC will be ignored, and .ZC
will be used.

The ZQR file produced by the quick reference document generation
option is always named after the ZC file.  For example, the ZQR
file for DATA.ZC is DATA.ZQR.
                                                             3-16

Modifying Configuration Files

You may modify a configuration file at any time, by selecting
option 3 from the main menu, or by invoking ZIPKEY 3 from the DOS
command prompt.  You may also include the name of the ZC file in
the DOS command prompt.  For example, ZIPKEY 3 DATA will cause
ZIPKEY to look for DATA.ZC. If the ZC file you wish to modify is
not found, ZIPKEY initiates a brand new configuration sequence,
but the first choice (Memory model) give you the option of
retyping the configuration file name in case you mistyped it.

The default choice in the configuration editing menu tells you if
you have made any modifications to the file.  If it is 8 (abort,
exiting without saving), you haven't modified the file.  If it is
7 (disk save), you have.


More Hotkey Examples

Here are the complete configuration specifications for a few of
the scenarios mentioned earlier in this chapter.  To work the
examples in this section, type ZIPKEY 3, then either walk through
a configuration process until you get to the "Hotkey name"
prompt, or select option 3, "Hotkey settings", of the
configuration editing menu.

First, let's configure so that the zipcode comes from the screen,
and the ZIPKEY window doesn't pop up at all if the zipcode is
found.  When prompted for the hotkey name, press the back-quote
key.  Select option 2, "From the zipcode near the current cursor
position on the screen."  Then type N, you don't want the screen
to pop up for confirmation if the zipcode is found.  For the
playback sequence, we'll assume that you want to erase the
just-typed zipcode and replace it with a letterhead: type

BBBBBC99, A Z{Enter}

and terminate with the * key.

Because we used a displaying key (the backquote key) as the
hotkey in the previous example, let's define another hotkey that
generates a backquote.  When prompted for the hotkey name, type
Alt-backquote.  Select option 3, fixed string, for the zipcode
source.  ZIPKEY then asks for the fixed specification, and you
type the double-quotes key " followed by {Enter} and the
terminating * key.  Your keystroke playback sequence then has
nothing to do with zipcodes: it is simply the backquote key
followed by the terminating * key.  Now if you need to generate a
back-quote, you can type Alt-backquote.
                                                             3-17

Next, let's handle the case in which a zipcode is typed twice:
once as a part of an identification code, and then later as a
part of the address.  When prompted for the hotkey name, type the
Z and the 1 keys simultaneously.  For the zipcode source, choose
option 1, "The operator types it in after the window is popped
up."  Since you used two non-shifting keys, one of the keys will
have been fed to your application program: you now wipe it out by
beginning the playback sequence with B.  Since the city and state
name aren't part of the identification code, the playback is just
the backspace and the zipcode: BZ followed by the terminating *
key.  Next you specify a second hotkey, named with the Z and 2
keys.  Since you are repeating the zipcode just looked up for the
identification code, you specify option 3, fixed string, as the
zipcode source.  ZIPKEY then asks for the fixed specification,
and you again type the double-quotes key " followed by {Enter}
and the terminating * key.  Then you type the keystroke playback
sequence: C17N{Enter}AZ{Enter}T- followed by the terminating *
key.

Finally, let's do an example in which we provide a fixed field on
a simple text editor.  The city field will be 19 characters wide,
starting at column 33 on a line, which is the fourth tab stop.
It will be followed by the state abbreviation and the zipcode.
For the hotkey name, press both Shift keys, then press the Z key.
Choose option 1 as the zipcode source.  For the playback
sequence, we assume that the Home key will put the cursor at the
start of the current line, so you can specify

   {Home}{Tab}{Tab}{Tab}{Tab}C19F A Z*

which will leave the cursor just beyond the zipcode.


Conclusion

This concludes the description of ZIPKEY configuration.  In the
next chapter we'll discuss how to arrange the ZC file together
with the other ZIPKEY files, so that ZIPKEY is permanently
available to you.

As you have seen, ZIPKEY has a wide array of options.  There is
often more than one method of handling a given configuration
requirement.  Which method you choose is often simply a matter of
personal taste.  If you are intimidated by the choices, then keep
things simple to start out with.  Like any complex program,
ZIPKEY will serve you best if you let yourself become familiar
with it before trying to exploit every feature.

CHAPTER 4   RUNNING MEMORY-RESIDENT ZIPKEY


This chapter assumes you have some familiarity with DOS concepts
and commands-- for example, it assumes you know what a
subdirectory is, and how to copy a file to a subdirectory.  If
you aren't very familiar with DOS (you run straight to your
word-processor and stay there when you turn your computer on),
you may need to have a DOS-knowledgeable person assist you.


Placing ZIPKEY Resident in Memory

In Chapter 3 we discussed how to create a ZC file to configure
ZIPKEY to your specific needs.  Once you have done so, you are
ready to run ZIPKEY as a memory-resident program.  You do so by
selecting option 4 of the ZIPKEY main menu.  You can also do so
directly from the DOS command prompt, by issuing the command

      ZIPKEY 4

followed by the Enter key.  If you have a ZC file named something
other than ZIPKEY, you include the ZC file name on the command
line.  For example, if you have a ZC file named DATA, either of
the following command lines will load ZIPKEY as a memory resident
program, using the configuration file DATA.ZC:

   ZIPKEY 4 DATA
   ZIPKEY DATA 4

The process of loading ZIPKEY as a memory-resident program causes
your computer to exit the ZIPKEY program, and return you to the
DOS command prompt.  You are now ready to run any other programs
you choose, but ZIPKEY is still in your computer's memory, ready
to be activated at any time by the hotkey or hotkeys you chose
when you configured ZIPKEY as described in Chapter 3.

As an example, let's assume you have defined a ZC file with the
two hotkeys we discussed in Chapter 3: one, F11, for use within
your database manager, and the other, F12, for use within your
word processor.  Having loaded ZIPKEY as a memory-resident
program, you can now enter either your database manager or your
word processor to see if ZIPKEY works.  You reenter your database
manager, just as you did before you configured ZIPKEY, to type in
a sample address.  Just as before, the database manager puts an
address template onto the screen.  You type in a sample name and
street address; but instead of typing the Enter that will advance
you to the city field, you type the F11 hotkey instead.  The
ZIPKEY window pops onto the screen, inviting you to type a
zipcode specification.  (If it doesn't, see the section "ZIPKEY
and Other Memory-Resident Programs", later in this chapter.)  You
may type any specification as described in Chapter 2.
                                                              4-2

For most business applications, you will already have the zipcode
available to you, and you will be using ZIPKEY to make the data
entry faster and more accurate.  You type in a zipcode, 31625,
and get the city Barney, GA for confirmation.  You confirm with
the Enter key.  Now, if you defined your keystroke playback
sequence to duplicate what you would have typed to your database,
you should see the city, state, and zip fields of your address
template filled with the correct values.

What do you do if the template is not filled correctly?  You need
to determine if you got the keystroke playback sequence right.
If the city/state/zip appears to be there but is in the wrong
fields, then it's likely that you got your cursor-positioning
keys wrong -- either too many or not enough.  You should repeat
the exact keystroke sequence used to enter city/state/zip, and
make sure that is the sequence specified to ZIPKEY's
configuration.  You can get a listing of what you specified by
printing out the ZQR (Zipkey Quick Reference) file that you can
create via option 7 of the ZIPKEY configuration editing menu.
For example, if you created ZIPKEY.ZQR, type the command

   COPY ZIPKEY.ZQR PRN

to the DOS command prompt, and the listing will be sent to your
printer.

If ZIPKEY appears to be playing back only every second or third
letter of the city/state/zip, then your program needs the
keyboard slowdown option, one of the general option settings of
the configuration.

In any case, if a configuration change needs to be made, follow
the instructions in the next sections to replace with a new
configuration.

Having checked out the database manager, you need to move on to
the word processor.  You exit the database and invoke the word
processor.  You type a sample name and street address.  Instead
of typing a city name, you press the F12 key, and the ZIPKEY
window pops up once again.  Now type 23054 to get the entry Fife,
VA.  When you press the confirming Enter key, the complete
specification Fife, VA 23054 appears, the cursor is positioned at
the second line below.  Again, if you didn't get the right
results, you need to figure out whether you got the playback
sequence right.


Correcting Your Configuration

If your check-out of memory-resident ZIPKEY revealed some changes
you need to make in the configuration, you may do so by typing

   ZIPKEY 3
                                                              4-3

followed by the ZC file name if it isn't ZIPKEY, to the DOS
command prompt.  The choice "General options" followed by several
presses of the Enter key will get you to the "Slow down keyboard"
option, which you can change to Y if your program was missing
regularly-spaced keystrokes.  You may wish to temporarily slow
down the keyboard even if this wasn't the problem, so that you
can more easily watch the playback to diagnose how you got the
sequence wrong.

The option "Hotkey settings" will change the keystroke playback
sequence for a specific hotkey.  You need to repeat the
specification sequence, giving the hotkey name, zipcode source,
and the corrected playback sequence.

When you have made your changes, you can type Enter to the ZIPKEY
configuration menu, to execute default option 7, the disk save,
which puts you back to the ZIPKEY main menu.   Press Enter again
to execute default option 4, to make the new ZIPKEY configuration
resident.


Removing a Previously Resident ZIPKEY

You may reverse the ZIPKEY 4 command with option 7 of the main
menu, which can be executed directly from DOS with the ZIPKEY 7
command.  This option removes ZIPKEY from memory.  If there have
been no other memory-resident programs placed after ZIPKEY, the
memory occupied by ZIPKEY is freed back for your other programs
to use.  In some systems, such as those running Sidekick, a short
stub of 200-300 bytes must be retained by ZIPKEY after its
removal.



Replacing a Previously Resident ZIPKEY

In most cases, you do not need to remove resident ZIPKEY in order
to make a new configuration resident.  You can simply repeat the
command to place ZIPKEY resident -- either option 4 from ZIPKEY's
main menu, or the DOS command ZIPKEY 4 followed by the ZC file
name if it isn't ZIPKEY. You may replace after you have modified
the ZC file already installed, or you may replace to change ZC
files.  ZIPKEY will detect that it was already resident, and
simply substitute the new configuration.  You'll be back at the
DOS command prompt, ready to invoke ZIPKEY within your programs
again.

There are only two situations in which you need to execute ZIPKEY
7 to change configurations:

1. If you change the location of ZIPKEY's database -- EMS memory
   vs. stay-on-disk vs. main memory -- this one change will be
   ignored when resident ZIPKEY is replaced, and not take effect
   until after resident ZIPKEY is removed.
                                                              4-4

2. If the new ZC file is more than 256 bytes bigger than the
   first ZC file made resident, ZIPKEY will tell you that the new
   ZC file is too big, and the new configuration will not take
   effect.  ZC files are usually much smaller than 256 bytes, so
   unless you have unusually complicated configurations, you
   won't have this problem.  If you do, you should make sure that
   your largest ZC file is loaded first when your computer starts
   up.


Making ZIPKEY Permanently Available

The MS-DOS operating system has a mechanism that allows you to
specify that certain programs should be run every time your
computer is started.  You create a file called AUTOEXEC.BAT, on
the same disk drive from which the operating system is loaded.
If you have a hard disk system, this is usually drive C.
AUTOEXEC.BAT is a text file, containing lines that you might type
to the DOS command prompt to run programs.  Every time your
computer is started, MS-DOS reads the AUTOEXEC.BAT file and
pretends that the first commands you typed into your computer are
the commands in that file.

ZIPKEY's INSTALL program will, with your approval, modify your
AUTOEXEC.BAT file to include a line that will install ZIPKEY
whenever your computer is started.  If you didn't elect to do so
when you first installed ZIPKEY, you may rerun INSTALL at any
time, to add the line.


ZIPKEY and Other Memory-Resident Programs

If you have other memory-resident programs placed at the same
time as ZIPKEY, you may need to experiment a little to determine
the best order in which to load the programs.  You would do so by
moving the ZIPKEY line within the AUTOEXEC.BAT file, by using a
text editor such as the program EDIT that comes with recent
versions of DOS.

Memory-resident programming is extremely tricky, and the
techniques are non-standardized and poorly documented.  A
resident program must monitor all the keyboard's signals to the
computer, while passing those signals to all the other resident
programs as well.  I believe ZIPKEY does a good job of this,
passing along every keystroke received except for its own
hotkeys.  But other memory-resident programs may not do a good
job: they may prevent certain keystrokes from being seen by
ZIPKEY, so that a ZIPKEY hotkey won't pop up ZIPKEY's window.
They may even become extremely confused and freeze up your
computer when ZIPKEY is invoked, forcing you to shut down and
restart the computer.
                                                              4-5

A specific example: Borland's Sidekick (the program SK) insists
that it be made resident after other resident programs such as
ZIPKEY, and with good reason.  You can get away with running one
program after SK that monitors keystrokes directly, but if you
run two such programs, SK locks out the first program and usually
locks out your keyboard as well.  So if you run ZIPKEY after SK,
and then run a text editor such as BRIEF or XYWrite, your
computer locks up.  If you make sure ZIPKEY appears before SK in
your AUTOEXEC.BAT file, there is no such problem.

A reverse example: Borland's SUPERKEY program must be run before
ZIPKEY. If you run SUPERKEY after ZIPKEY, the last keystroke you
typed to ZIPKEY's pop-up window (typically Enter) will be seen by
your program as well.

If ZIPKEY works in its demonstration mode (ZIPKEY 2), but not in
memory-resident mode (ZIPKEY 4), you should try ZIPKEY with all
other memory-resident programs removed.  You do this by renaming
your AUTOEXEC.BAT file to something else. For example, if your
current directory contains AUTOEXEC.BAT, you can issue the
command

   REN AUTOEXEC.BAT AUTOEXEC

to temporarily remove the .BAT extension from the file.  Then
shut down and restart your computer.  When the computer is
restarted, make ZIPKEY resident via ZIPKEY 4, and try to invoke
it with a hotkey.  If ZIPKEY now works, you know that some other
memory-resident program is interacting poorly with ZIPKEY.  You
can invoke the other memory-resident programs one at a time,
trying ZIPKEY after each one, to find the culprit. It's possible
that they will all load successfully and ZIPKEY will still work
-- in that case, you simply place the ZIPKEY invocation at the
start of the AUTOEXEC.BAT file, so it is loaded first.

When you have sorted things out, don't forget to rename your
AUTOEXEC file back to AUTOEXEC.BAT.


Finding ZIPKEY Files on Your Disk

When you set up ZIPKEY to be permanently available, you need to
make sure that the ZIPKEY files are placed on your disk where
they can be found.  This section describes how to do so.

Normally, when you give the name of a disk file to your computer,
you must let the computer know where it can find the file.  If
the file is on a floppy drive, you give the letter of the drive;
for example, A:ZIPKEY.OVL.  If the file is on a hard disk drive,
you might also need to name a subdirectory on the drive; for
example, C:\ZIPKEY\ZIPKEY.OVL.  To reduce this burden, DOS
maintains a "current drive" and "current directory", which act as
the defaults if you don't give a drive letter or subdirectory.
For example, the commands

    C:
    CD \ZIPKEY
                                                              4-6

make C the current drive and \ZIPKEY the current directory, so
you can refer to ZIPKEY.OVL instead of C:\ZIPKEY\ZIPKEY.OVL.

DOS's command processor adds an additional embellishment to the
current-drive-and-directory concept.  When you issue a command
such as ZIPKEY to DOS, it will look for the program file
ZIPKEY.COM first in the current directory.  If it doesn't find
ZIPKEY.COM there, it can be instructed to look in other default
directories, until ZIPKEY.COM is found.  You specify the list of
other default directories by the PATH (or SET PATH=) command,
placed into your AUTOEXEC.BAT file.  For example, your
AUTOEXEC.BAT file might contain the line

    PATH C:\DOS;C:\UTILS

or the equivalent line

    SET PATH=C:\DOS;C:\UTILS

to specify that programs may be found in the directories C:\DOS
and C:\UTILS as well as the current directory.

For convenience, ZIPKEY also recognizes the PATH command to find
its auxiliary files: ZIPKEY.OVL and the ZC file.  For example, if
your AUTOEXEC.BAT does contain the previously-mentioned PATH
specification, you may place ZIPKEY.COM, ZIPKEY.OVL, and your ZC
files into the C:\UTILS subdirectory.  Just make sure that the
PATH command in your AUTOEXEC.BAT comes before your ZIPKEY
command.  Then you won't have to worry about what the current
directory is when ZIPKEY is invoked.

Alternatively, if you want to keep ZIPKEY by itself on your disk,
you can provide the full path name on the ZIPKEY invocation line.
For example, you can place ZIPKEY.COM (evaluation version is
ZIPKEY.EXE), ZIPKEY.OVL, and *.ZC into a directory called \ZIPKEY
on the C drive, and make ZIPKEY resident with the command

   C:\ZIPKEY\ZIPKEY 4

If your version of MS-DOS is V3.0 or later, ZIPKEY will look in
the directory of its invoked program to find the ZIPKEY.OVL and
.ZC files.  On older versions of MS-DOS, you will need to change
the current drive and directory to ZIPKEY's directory so that
ZIPKEY can find its auxiliary files.

The only crucial factor here is the file-finding situation at the
time ZIPKEY goes resident (the ZIPKEY 4 command).  After that,
you may change the current drive and/or directory to anything you
want, and ZIPKEY will always find the files it needs.  The only
exception: if you run ZIPKEY from a floppy disk and you have
configured ZIPKEY to take its data from the disk, you cannot
remove the disk containing ZIPKEY.OVL-- it must still be there so
ZIPKEY can read it.
                                                              4-7

When deciding whether to place ZIPKEY into a PATH directory, you
may wish to consider the ease with which you would like ZIPKEY to
be invoked for modifying and reloading configurations.  With
ZIPKEY in a PATH directory, it can be invoked at any time without
changing the current directory.  If you modify an existing ZC
file, ZIPKEY will find and rewrite the file wherever it is.  (New
ZC files are always written to the current directory.)  This is a
powerful and convenient feature.  On the other hand, if you have
untutored users on your computer for which you consider such
power too dangerous, you may deliberately place ZIPKEY in a
non-PATH directory, to make careless modifications a little more
difficult.

CHAPTER 5   GENERATING AN ORDER FORM


Automatic Order-Form Generation

Because ZIPKEY is widely available on an evaluation basis, I felt
it necessary to make it easy for people to realize that ZIPKEY
isn't free.  So ZIPKEY has a special option 5 on its main menu to
generate an order for based on your usage, disk requirements, and
method of payment.  You may also execute this option directly
from the DOS command prompt, by issuing the command

   ZIPKEY 5

followed by the Enter key.  You'll also be invited to generate an
order form when making ZIPKEY resident (using the ZIPKEY 4
command), in two circumstances:

1. If your data is 13 or more months old, you'll be warned that
   it's out of date.  The postal service regularly makes changes
   to its zipcodes, so that you need fresh data to insure
   continued accuracy.  I'll be releasing new ZIPKEY.OVL files
   based on those changes monthly.  You are required to
   resubscribe and receive a new disk at least once a year; and
   you can elect to receive disks more often if you wish.

2. If you are running the evaluation version of ZIPKEY, and it is
   now the second month or later following the first creation of
   your ZC file, you'll be reminded that your evaluation period
   has expired, and invited to fill out an order form.

In either case, if you choose Y to the order-form invitation, you
will initiate the interactive session described in this chapter,
after which ZIPKEY will go resident as intended, and AUTOEXEC.BAT
(if that's where ZIPKEY was invoked from) will complete itself.

If you press N to the invitation, the order-form procedure is
skipped, and the computer continues normally, making ZIPKEY
resident and working just fine.  I'm not going to beat you over
the head with a club; I'm trusting that you'll answer Y
eventually.


ZIPKEY's Schedule of Prices

The pricing scheme for ZIPKEY is a little unusual in that it
involves the maximum, not the sum, of two fees.  The basic,
single-keyboard registration is $30, which buys you a printed
manual, a disk, and a year's license to run ZIPKEY in
memory-resident mode.  I felt that if you want disks more often
than once a year, you should pay more.  And if you wanted to
license more keyboards you should pay more.  But I also felt that
if you chose either price-increasing option, you should
automatically be entitled to the other at no extra cost.  I can't
explain it beyond that -- it's simply what seems fair to me.
Hopefully I can implement this scheme without too much confusion,
thanks to ZIPKEY's ability to figure out your subscription price
for you.
                                                              5-2

So your subscription fee is the greater of two qualifying
amounts: the materials fee and the license fee.

The materials fee is $25 for every diskette mailed to you, plus
$5 for every printed manual mailed to you.  You may copy the
contents of a single disk onto all computer systems for which you
have licensed ZIPKEY, so you do not need to order multiple copies
of the same diskette.

The license fee depends on the number of keyboards accessing
ZIPKEY.  Keyboards using ZIPKEY only in its demonstration mode
(ZIPKEY 2) have a one-time, perpetual license fee fee of $10.
Keyboards using ZIPKEY as a memory-resident program (hotkeys, key
playback, and/or program interface) have a sliding scale of
annual fees: $25 for the first keyboard, $20 each for the second
and third keyboards, $15 each for the next five keyboards, and
$10 each for all subsequent keyboards.

Again, the total charge is the maximum, NOT the sum, of the
materials and license fees.  This means, for example, that if you
would like to receive disks quarterly (materials fee $100), you
may license 5 memory-resident keyboards (license fee $95) for no
extra charge.  Conversely, if you license a lot of keyboards, you
may be able to receive disks more often for no extra charge.


Gathering Your Order Information

Before answering ZIPKEY's order form questions, you should take a
census of the number of keyboards you wish to license.  (I refer
to keyboards, not computers, to resolve questions raised by
networks.)  The non-resident keyboards are those from which
ZIPKEY is accessible, and from which occasional ZIPKEY 2 commands
are issued to look up zipcodes in demonstration mode, but which
the ZIPKEY 4 command is never issued.  The resident keyboards are
those for which ZIPKEY 4 is issued, and use any or all of the
following: hotkeys, keystroke playback, or the programmatic
interface.  If you use the programmatic interface to produce an
unpacked zipcode database file from ZIPKEY.OVL, then you must
also license any keyboards that access that database file, even
if they don't run ZIPKEY directly.

You should also decide how you will pay for your order, by
obtaining either a purchase order number or a credit card number
(Visa, Mastercard, or American Express), or by seeing to it that
you can obtain a prepaid check.  Keep in mind that you must be
either an established customer, a Fortune 1000 corporation, an
accredited school, or a government agency to issue a non-prepaid
purchase order.  Also, there is a $5 surcharge for non-prepaid
purchase orders under $100.
                                                              5-3

Answering the Order-Form Questionnaire

Now you're ready to answer the order-form questionnaire.  You'll
first be asked the number of non-resident, then resident
keyboards you are licensing. If this is a simple, one-keyboard
registration, you'll answer 1 for one of them and 0 for the
other.  If you are renewing a license, you don't need to
redeclare the non-resident keyboards-- their license is
permanent.  You do need to redeclare the resident keyboards.

What about keyboards that change resident vs. non-resident
status?  You declare the newly resident keyboards, and not the
newly non-resident ones.

Next, ZIPKEY asks for the number of printed manuals you'd like.
You may order any number from zero up to the number of keyboards
being licensed.

Next, ZIPKEY asks for the number of years you are paying for.  I
expect almost everyone to answer 1 to this question; but I myself
like to pay off my utilities bills for months in advance, so
maybe somebody out there will be like that.

ZIPKEY then asks for the number of disks per year to be
delivered.  This number multiplied by the previous number gives
the total number of disks you are paying for with this order.
You'll get one disk immediately, and the rest in evenly-spaced
periods.  The disk to be shipped exactly one year from now is
part of next year's order.

You are then give a choice of disk type.  Choice 1 is the
older-generation, 360K flexible-sleeve floppy.  Choice 2 is the
newer (PS/2 style) hard-shell, 720K disk.

You are then prompted for your name, address, and telephone
number, followed by the choices for method of payment.  If you
choose a credit card or purchase order number, you'll be prompted
for the additional information.

After the payment information is given, the order form is
complete.  The only remaining choice is whether to send the form
directly to the printer, or to a disk file or device.  Make sure
your printer is turned on before sending it to the printer.


Possible Amendments to the Total Price

The order form that ZIPKEY outputs includes the total price of
the package calculated for you.  There are only two things that
could add to the total:

1. If your shipping address is in Indiana and you are not exempt,
   you must add sales tax (5% at this writing) to the total.

2. If your shipping address is overseas, add $2 per disk and $3
   per manual to cover extra postage.  There is no extra charge
   for postage on domestic orders.

CHAPTER 6   PROGRAMMATIC INTERFACE


If you are writing a computer program and wish to call ZIPKEY
from your program, you may do so.  The complete descriptions of
the function calls, with sample calling code, is given in the
file ZPROG.DOC on your disk.  The following chart gives the
overview of calls to ZIPKEY's INT 179 (hex B3), as a quick
reference when you are writing your code:

INT 179 with AH=

070H   ZK_VERSION sets AX,CL,DX to version information
071H   ZK_ABBR_ST converts abbr. BX to state code AL
072H   ZK_ST_ABBR converts state code BL to abbr. AX
073H   ZK_ST_NAME outputs state BL's name to ES:DI
074H   ZK_ZIP_DIGITS outputs zipcode DXCH to ES:DI
075H   ZK_ZIP_ST sets AL=state BX=area code for zipcode DXCH
076H   ZK_ZIP_CITY outputs city name DXCH to ES:DI
077H   ZK_ZIP_KEYS plays exit key #BX for zipcode DXCH
078H   ZK_STCITY_ZIP sets BH to #cities DS:SI for state BL
079H   ..or ZK_CITY_ZIP for any state starting with BL
07AH   ..then ZK_CASE_ZIP sets DXCL-CH to case #BL
07BH   ZK_SAVE sets BX,CX,DX to ZIPKEY's context; BL=city width
07CH   ..then ZK_RESTORE restores ZIPKEY's context
07DH   ZK_POPUP pops up as if hotkey #BL were pressed
07EH   ZK_REGION_CITY outputs region DX to ES:DI; sets AL=state
07FH   ZK_SWITCH BL=0/1/2/3 en/dis/show/togg hotkeys; 6=newprog
080H   ZK_AREA_ST converts area code BX to state AL, 1st region DX

If Carry is returned, then if AL=

   0FDH  ZIPKEY is busy.
   0FEH  Illegal AH function number.
   0FFH  Search failed without even a suggested value.
