Is Split Buggy? Why Isn't 0 a Number?

[Tygur]

To make the above code work with variants and negative numbers, there has to be some changes:

Dim V As Variant
V = -1500
Select Case V
    Case "-" To "9"
        MsgBox "Number"
    Case Else
        MsgBox "No Number"
End Select

But now it lets through strings that begin with a "/"..

Kinda surprising that "Case True, False" works so well..
