1. Introduction
~~~~~~~~~~~~~~~
This is a simple program to calculate the GST, PST(or any two taxes), and
total amount for any given subtotal, and which can also calculate
taxes-included pricing.  It's useful for consumers, who can save a little bit
of time figuring out the total cost of an item, and useful for professionals
who may have to write out bills at a client's site.  Restaurant owners who
price their beverages with taxes included will find this program invaluable.

For instance, the consumer who sees an ad for a computer costing
$1742.55 can simply double-click their sales tax calculator icon and
type 1742.55 and find out how much it would cost, while the computer
consultant writing out a bill can put his disk in his client's drive
and quickly determine the taxes and total owed, while eliminating errors
and time spent fumbling with the math.

The program defaults to calculating 7% GST and defaults to 8% Ontario PST.
It allows full customization of tax rates and descriptions, has a calculator
function, and allows either or both taxes to be exempted, or to be
compounded on top of each other.  It will also calculate taxes-included
pricing.  You can also copy the tax amounts and total and paste them into
another application, and add up a number of items by using the + and - keys
to add and subtract from the total.  The program can also be set to always
stay on top of other Windows applications.

Sales Tax Calculator for Windows will run on any computer with Windows.
It is compatible with all flavours of Windows, including Windows 3.x and
Windows 95/98.  You must have the file VBRUN300.DLL in your Windows/System
directory.  If you don't have this, it can be downloaded from the CCS
web site.


2. Usage Instructions
~~~~~~~~~~~~~~~~~~~~~
The Sales Tax Calculator is a very simple, intuitive program.  You should
be using it within seconds, even if you don't read this section of the
documentation.

To use this tax calculation program, simply double-click your sales tax
calculator icon, and fill in the amount.  To run from a floppy, simply
do File, Run, a:taxw.exe in Windows 3.x, or go to Start menu, Run,
a:taxw.exe in Windows 95.

To exempt either or both PST or GST, simply click in the check box beside
the tax you want to exempt.

To change either tax rate, click in the percentage box, and type in your new
tax rate.  Eg. For 10%, type 10.

To customize the names of the taxes, click on their names and type in new
names.  No colon is necessary.  Eg. To change GST to HST, click on GST:,
then type HST and press Enter.  The tax description will now read "HST:"

To compound one tax on top of another, click Options, then choose which
compounding option you want.

To calculate taxes-included pricing, click Options, then choose Tax-Inclusive
Pricing.  Then type in the price you want to sell for, and the program will
display the base price before taxes, and the taxes.  In cases such as $150
at 8% and 7% taxes, which has a base price of $130.43 which only adds up
to $149.99, and $130.44 jumps to $150.01, then the base price will display
in red.

To paste a tax amount or total into another application, highlight the
amount and press CTRL-C.  Then switch to your other application, and
press CTRL-V.

To add up the taxes on more than one item, enter an amount, press the "+"
key, and enter another amount.  If you make a mistake, use the "-" key to
subtract from the total.  When you have entered your last item, press Enter.

To use the calculator, for instance to add up a subtotal, simply click the
calculator button.  This calls the Windows Calculator accessory, which is
installed by default on any Windows installation.  

To have the program always stay on top of other Windows applications,
choose Options, Always on Top.

To save your settings, click on File, Save Settings.  Your settings are
saved in the file TAXW.DAT.


3. PGP Authenticity Verification
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
My PGP key is in the file MARKPGP.ASC, and is also available from the
Internet keyservers, or you can e-mail me requesting it.

To check that the files have not been altered, run "pgp taxw.sig taxw.exe",
then run "pgp taxw.txt".  If you don't get a good signature, don't trust
the copy you've got, and e-mail me for a good copy.

The official distribution is a .ZIP archive called TAXW19.ZIP,
which contains MARKPGP.ASC, TAXW.TXT, TAXW.EXE, TAXW.SIG, ORDER.FRM
and FILE_ID.DIZ.

The latest version of PGP is 2.6.3i, and it is available on the Internet from
ftp://ftp.cert.dfn.de/pub/tools/crypt/pgp/pc/dos/pgp263i.zip or from any
number of sites around the world, including the Carter Computer Solutions
