First off, it's equal to the class name until its .init() exits; then it gets a number appended, which is usually 1 (for the first instance) but not necessarily so (other instances, code setting the form's name). I'd rather check for class, though - assuming the forms were class based; if not, there should be a function. SCX() maybe?

That is just an example of how to find if some form exists.
Instead of Name we could use Caption or other property to distinct form.
I often use one form for more than one purpose depending of parameter I passed to it, so the SCX name is not an option (for me :-)) I always set the name to some distinct values (again this is only me). So I am not sure WHAT makes the form different than the same form but called with different parameter.
