This Web page shows a simple example that uses the Tcl
plug-in for Netscape Navigator. Enter information about a home
loan in the three entries, then type Return in any of the entries or
click on the
Calculate button. The Tcl applet will compute
the monthly payment for the specified loan and display it just below
the entries. In addition, it will create a graph that shows how much
of the loan principal has been repaid after each year of the loan.
If you move the mouse over the bars in the graph, additional information
about that year will be displayed under the graph.
