<lang freebasic>Dim As Integer s(1 To 7) => {1,2,2,3,4,4,5}
For i As Integer = 1 To Ubound(s)
Dim As Integer curr = s(i), prev
If i > 1 And curr = prev Then Print i
prev = curr
Next i
Sleep</lang>

Like the first/unchanged JavaScript example, no output.<br>
Obviously you can achieve consistent results by manually hoisting the declaration of prev to before/outside the loop.
