Hi,
Thanks to all who sent me info re: Mortgage Calc scripts.
Rhythmist, thanks much for the code snippet, that's really what I was
looking for.
FYI, here's a CGI mortgage calc that I like:
http://www.gotitle.com/mortgage/
I like how it let's you run a few calc's and shows the previous results to
refer back to.
I also found this comprehensive java app calc:
http://www.jeacle.ie/mortgage/ (warning - java!)
It has a lot of variables and different ways to look at the results, though
no source code available.
Thanks,
Jack
