API Command for Not solved Equation

Hi Everyone,

I am new to the Macros.
After deleting features and sketches from a model through APIcalls, I try to clean up the non-evaluated equations that are leftbehind.
When I look in the Equation Dialogue box, the equation have novalue (i.e. they have an exclamation mark beside them). How can iget the not solved equations? Any idea? Is there any API Commandavailable to get not solved equations?

Thanks in Advance,
