I'm of two minds here. Sometimes when I want a reference to the calling form, I will pass it as a parameter. Sometimes, I will rely on _SCREEN.Activeform in the load of the Called form. But since I've found that _SCREEN.Activeform is not so reliable, I prefer the explicit passing of the reference to the form.

As far as program() is concerned, I believe one advantage would be that you could use that information in the load instead of waiting until the init, but again you are relying on the call stack instead of explicitly passing it which may be safer.
