Duplicate the Split Function for VB4 and VB5

It's too bad Microsoft didn't create the Split function until VB6, but here's a function that duplicates it for VB4 and VB5 users. The only difference is that with VB4 and VB5, you must use a Variant to receive the Split data, whereas VB6 can also use a dynamic String array:
Public Function Split(aText As String, _
	Optional vSrch As Variant) As Variant
	If IsMissing(vSrch) Then vSrch = " "
	Dim j As Long, k As Long, a As String
	ReDim s(0) As String
	a = aText
	k = InStr(a, vSrch)
	Do While k
		If j > UBound(s) Then
			ReDim Preserve s(0 To j) As String
		End If
		s(j) = Left$(a, k - 1)
		a = Mid$(a, k + Len(vSrch))
		k = InStr(a, vSrch)
		j = j + 1
	If Len(a) Then
		If j > UBound(s) Then
			ReDim Preserve s(0 To j) As String
		End If
		s(j) = a
	End If
	Split = s
End Function
Dim vDat As Variant
vDat = Split("This is a test")
' vDat(0) = "This"  vDat(1) = "is", etc...
