Programming Help

I believe it is not possible to make an interactive INPUT form at the moment. What you can do, however, is allow the user to enter an "S" (you will need to add another allowed type into your INPUT command). Then once the user presses OK or the ENTER key, you can search for which variables has an "S" and solve for those variables.

If you are trying to set up an equation solver, perhaps the solve app might be a better place to start. Clone the solve app, set up your variables and equations, and use the STARTVIEW command to enable the app.

Lastly, if you just want a solver (as opposed to trying out some programming for yourself) that will save your equations, try SolveSys (link in my signature below).

(Don't forget there is a built-in documentation on the calculator itself!)
