They are not the same but they do share some of the properties (e.g. ActiveForm, Forms collection).

_Screen is a special implmentation of a Form class and _VFP is not. As such, _Screen has all the methods and properties associated with forms. You can add objects using AddObject or NewObject. _VFP has none of these capabilities.

Take a look in the VFP help for a more thorough explanation of what _VFP and _Screen contain.
