Clearing larg 2D user type arrays?

What is the best way to clear a larg 2D user type array?
Something as big as about PathClosed(100000000,100000000)

For a Ststic array:

Code:

---

Erase PathClosed

---

and if your array was dynamic

Code:

---

Redim PathClosed (#####,#####)

---

##### represents whatever numbers you are using
