Hi Benoit,

Public Sub Main()

   For n As Byte = 0 To 9
     Dim v As Byte
     Print v
     Inc v
     Print v
     Print n
   Next

   Print "==========================="

   Dim sStr As String[] = Split("Any phrase of this book", " ")
   For Each s As String In sStr
     Print s
   Next
   Print "---------------------------"
   Print n
   Print v
   Print s
   If sStr Then Print "sStr exist"

End

Would not it be more logical to expect that only sStr existed after the For
blocks?

Regards
Gianluigi
