[Solved] HP48G How to calculate / record into form fields?

[Nick]

On the HP48G, for example:

-> SOLVE finance (though this question applies to any form in general)

The cursor is on field N by default ready to accept a number.

In financial applications, I'm used to being able to calculate a value for entry.

In HP terms, I'd like to be able to enter the result of '12*30' or <<12 30 *>> or maybe drop into the stack calculate a result, then return it to the form.

I know this can be done with the direct variables and alternate solver entry. Can this be done from the form UI?

Thanks,
Nick
