ArrShortestItem - The value and index of the shortest element of an array of any type

' The shortest item in an array of any type
' (it applies the LEN function to all the items in the array
'  and then takes the highest value)
' FIRST and LAST indicate which portion of the array
' should be considered; they default to the first
' and last element, respectively
' if SHORTESTINDEX is specified, it receives the index of
' the longest element of the array

Function ArrShortestItem(arr As Variant, Optional ByVal First As Variant, _
    Optional ByVal Last As Variant, Optional ShortestItem As Long) As Variant
    Dim index As Long
    Dim minLength As Long
    If IsMissing(First) Then First = LBound(arr)
    If IsMissing(Last) Then Last = UBound(arr)
    ArrShortestItem = arr(First)
    minLength = Len(ArrShortestItem)
    ShortestItem = First
    For index = First + 1 To Last
        If minLength > Len(arr(index)) Then
            ArrShortestItem = arr(index)
            minLength = Len(ArrShortestItem)
            ShortestItem = index
        End If
End Function
