Description Assigns an object reference to a variable or property .
Nothing Discontinues association of objectvar with any specific object. Assigning objectvar to Nothing releases all the system and memory resources associated with the previously referenced object when no other variable refers to it. The Dim , Private , Public , or ReDim statements only declare a variable that refers to an object. No actual object is referred to until you use the Set statement to assign a specific object. Generally, when you use Set to assign an object reference to a variable, no copy of the object is created for that variable.
