Oops!

Sorry about this, But I didn't notice the disappearance of one of the
substrings due to a bit of confusion with the split method returning a
zero base array, while the other arrays were one base.

this version retains all substrings...

Dim rngSortRange As Range
Set rngSortRange = Application.InputBox( _
"Select the range of cells for internal sorting", _

Dim strNumPart As String
Dim vaArray() As Variant

Dim I As Integer
Dim J As Integer

Case "0", "1", "2", "3", "4", "5", "6", "7", "8", "9"
strNumPart = strNumPart & Mid(StrSubStrings(I), J,
1)
End Select

ReDim Preserve vaArray(2, I + 1) As Variant
vaArray(1, I + 1) = StrSubStrings(I)

rngCell.Value = Join(strFinal, ", ")
