- This application works with all versions of RISC OS.

- Introduction
- ~~~~~~~~~~~~
- Finance was my first real foray into WIMP programming. I had written numerous programs to run
- outside the desktop, but this was my first desktop application. I hope someone out there will
- find it useful.
-
- How to use !Finance
- ~~~~~~~~~~~~~~~~~~~
- Double-click on the icon in the directory viewer to load the program. The program will install
- itself on the right-hand side of the icon bar. Clicking with SELECT or ADJUST over the icon
- brings up the main window. Here there is a space to enter the initial amount, interest rate (as
- a percentage), time to pay back (in months) and, if any, deposit (as a percentage). If you try
- to calculate without entering values for the first three prompts you will get a message telling
- you to enter the relevant information. Pressing RETURN with the caret on the screen will move
- to the next section, and after the last one, calculate the amount.
-
- The two radio buttons directly above the results window allow you to select the interest type.
- Simple interest - Interest is only paid on the initial amount.
- Compound interest - Interest is paid on the interest, as well as the initial amount.
-
- The variable windows are not emptied after interest is calculated, or when the window is closed.
-
- The icon bar menu gives information about the program, a calculator utility and the quit option.
-
- The calculator layout is similar to the standard Acorn one supplied in ROM on RISC OS3 machines.
- The main difference is that as you enter a sum it adds to the sum in the window, so you can
- perform more than one step at a time. (This isn't a very good description, so try it yourself.)
-
- NOTE: This program was written on an A3010 and has been tested on an A7000 so should be fairly universally workable.
