Calculate and print an amortization table for level monthly payments 
with or without a balloon.  Show totals, balances, etc.  Give special 
attention to preventing round-off errors.

Input values are:

    Title of Schedule - Text Title of the Schedule to be printed at the 
    top of each page.

    Loan Amount - The loan amount in dollars and cents.  Do not use 
    commas or dollar signs.  Decimals are permitted.

    Annual Interest Rate - The interest rate, in percent, for the loan.

    Payment Amount - The payment in dollars and cents.

    Date of Loan - The month number, day number in the month, and year 
    separated by commas.  For example:  September 13, 1987 = 9,13,1987 
    and August 1, 1988 = 8,1,1988.  The schedule will use this date to 
    calculate the date of future payments.  It allows for the number of 
    days in a month and leap years and adjusts the payment date 
    accordingly.

    Is this a balloon? - answer Yes or No then provide the date of the 
    last payment or the number of the last payment.

    Calculate the amortization schedule and print it on the default 
    printer.
