Using "pure" VB, the only way to build a generic routine that returns the number of dimensions of an array passed as an argument is using a loop that repeatedly tests the LBound (o UBound) function until it fails:
Function ArrayDims(arr As Variant) As Integer
Dim i As Integer, bound As Long
On Error Resume Next
For i = 1 To 60
bound = LBound(arr, i)
If Err Then
ArrayDims = i - 1
Exit Function
End If
Next
End Function
