Program: A or S box
By: David Billigmeier

   What this program does is determines
A box, S box, A double dot box, or S
double dot box.  These are formulas used
in theory of interest to determine future
and present values of annuities.

HOW TO USE:
   Start the program and choose which
formula you want.  The program will ask you
for the interest rate (i) and the number
of payments (n).  It will then spit out a 
number, all you have to do is multiply or
divide that number by the corresponding FV,
PV, or payment amount to get what you want.
I can't be anymore precise than that, its
kind of hard to explain these formulas to
anyone who hasn't taken a theory of interest
class.  If you have taken it you should
know exactly what I'm talking about.


Feel free to modify this program to better fit
your needs, open it up and check it out.  Feel
