An array is one object with 1 or more elements

Code:
Dim myObject(4) as Object
Would define
myObject(0)
myObject(1)
myObject(2)
myObject(3)
myObject(4)

You can use redim to change the number of elements at runtime.

Code:
ReDim myObject(10)
This will erase any values stored in the array. If values need to be retained then you can use the Preserve keyword

Code:
ReDim Preserve myObject(10)
