>I am looking for modules which perform finacial calculations (such as those loan calculators found on many automobile websites) for use in an application my employeer is developing. If anyone can point me in the right direction, it would be greatly appreciated.

I have written several apps that incorporate these types of calculations. If you let me know specifically whan you are looking for, I might be able to post some code that shows how to do it.

VFP has several built in functions that make a lot of this simple:
PAYMENT(), PV(), FV().
