empty/clear an array

Hello All,

In VBA, I have an array that I can't seem to figure out how to clear. Below is the code...Thanks in advance for any help!

Dim arrayCodes(1 To 19) As String
Dim arrayLoad As Integer
arrayLoad = 1

For i = 3 To 19 'Loop for (columns)
            If Not IsEmpty(Cells(x, i).Value) Then
                arrayCodes(arrayLoad) = Cells(x, i)
            End If
            arrayLoad = arrayLoad + 1
Next i

'?? how do I clear the arrayCodes
