1:: Introduction
	The Universal Currency Exchange can convert any currency to any other currency, 
using their relative rates to an anchor currency (the default currency is the 
US Dollar, but you can change this (see chapter 3))  All currencies are defined 
by the user, and can be easily added or removed.  A virtually infinite number of 
currencies can be stored.  The currency names are stored in a string to 
protect them from accidental deletion.

2:: Files
 CURRENCY: The core program
 XESCROLL: The scrolling engine
 Luced: Miscellaneous data list
 Lucen: Encrypted currency names
 Lucer: Currency Rates
 (Str8 holds the names temporarily when the program is run)

3:: Converting and Changing Exchange Rates
	This is, of course, the purpose of the U.C.E.  When you choose 'convert' on the 
main menu, you will be presented with a 'From:' prompt and the name of the anchor 
currency.  This is actually a scrolling menu.  Press the up and down buttons to see the 
other currencies.  Once you bring up the currency you wish to convert from, press enter.  
At the prompt, enter the amount you wish to convert, then press enter.  Another scrolling 
menu appears at the 'To:' prompt.  Choose the currency you wish to convert to, and press 
enter.  The converted amount will be displayed. You will then be returned to the main menu
	To change a rate, choose that option on the main menu, and use the scrolling menu 
as described above to choose the desired currency.  The current rate will be displayed. 
Enter the new rate (number per anchor currency) and press enter.  It is recommended that you 
update all the rates once a month or before an international trip. You can find current 
currency exchange rates at http://www.oanda.com/convert/fxdaily
	Please note that the first currency in your list is your anchor currency 
and it's rate must always be one.  When you exit the U.C.E. after changing the rates, 
you will be prompted for the current date.  This tells you when you last updated the 
program.  You must input this date as a single number ('08062000', for instance), 
since it is stored a such in the data list.  Using a pair of slashes will 
divide the number (08/06/2000 = .00066667) and using a pair of dots will cause 
an error message (8.6.2000 is not a number). 

4:: Adding or Removing Currencies
	To add a currency to your custom database, choose the 'Add Currency' option on the 
main menu and input the name of the new currency.  Names can only be 10 characters long 
(which should be long enough).  Next input the exchange rate of this currency per the 
anchor currency.  Press enter and the currency is added to the end of the list.
	To remove a currency, choose that option and press enter.  Select the desired 
currency with the scrolling menu and when you press enter, the currency is deleted.
	To change the anchor currency (the currency all rates are relative to), 
simply remove the current anchor (the first currency in the list).  The 2nd currency 
will become the new anchor. Change it to one, or simply exit the U.C.E. and renter 
it, which will automatically set the rate of this currency to one.  You will now have 
to change the rates of all the other currencies to their new relative exchange rates. 
	You MUST exit the program normally (press exit on the U.C.E. Main menu)  If you 
break the program by pressing [ON], all your changes to the Currency name list will be lost.

5:: Contacting me
	If you have any questions, comments, or suggestions about 
this program, please e-mail me at mdduerbalkind@hotmail.com

The MDDB Programs web site has pre-made lists of currencies, 
current exchange rates, information on new versions, and other 
programs I have made, including Chess X.

	Because I believe in open source codes, this program is not 
protected, so feel free to look at my source code and e-mail me if you 
have questions.  But DO NOT use my code without asking me first and 
then crediting me, and DO NOT SELL THIS PROGRAM.

6:: Dedication
	U.C.E. version 1 is dedicated to South Africa, where it was 
coded on the shore of the Indian Ocean.  South Africa is a country 
of incredible beauty, wonderful people, and tragic polarities and 
challenges.  My father is South African, and thus his country 
holds a special place in my heart.

Bless and Blessed Be!
