User interface like Time Value of Money in 48GX

[miker]

Hi,

I have an application with several related equations and variables. I would like to write a program that behaves as the Time Value of Money does in the 48GX, allowing any of the variable to be solved if the others are known. Does anyone have or know of source code examples of that programming behavior?

I have used a custom MENU, as in the example on page 1-81 of the Advanced User's Reference; but, that does not have the variables on the screen that can be navigated to and all seen at the same time.

Thanks,
Mike
