These updates can take place anywhere in your form if your form has a property to store the reference. Now, when you get back from your form, the parameter object has the updated values and you can do whatever you need to with them. Kind of like global variables, only better!

Yes, it's still available in the calling routine. All you are "zapping" is the forms reference to the object, not the object itself.
