Set Basket(2) = New Apple(0.98, "Red", "Delicious",33)

Set Basket(3) = New Banana(0.32, "Yellow")

Set Basket(4) = New Apple(1.2, "Yellow", "Delicious",35)

' Declare a list of references to base class: a Fruit Bucket.

Dim Bucket List As Fruit

Set Bucket("1") = New Apple(0.86, "Green", "Macintosh", 24)

Set Bucket("2") = New Apple(0.98, "Red", "Delicious",33)

Set Bucket("3") = New Banana(0.32, "Yellow")

Set Bucket("4") = New Apple(1.2, "Yellow", "Delicious",35)
