Form and Gadget References

!!Form and !!Form.Gadget are both PML references. After the command:

!X = !!Form.Gadget

!X is now a new reference, but the gadget itself has not been copied. Both PML variables now refer to the same gadget.

!X.val = 'New Value'

!!Form.Gadget = 'New Value'

This will both have the same effect and will assign a new value original gadget. You can think of a reference as another name for the same object or variable.
