Hi,

You can verify this yourself with an empirical code like this:

[code]

Private $aVariables As New String[]

Public Sub Main()

   Print myShortVar()
   Print myShortVar()
   Print myShortVar()
   Print myLongVar()
   Print myLongVar()
   Print myLongVar()

End

Private Sub myShortVar() As String

   Dim StartTime, DiffTime As Float
   Dim s As String = "test"

   StartTime = Timer
   For i As Integer = 0 To 1000000
     $aVariables.Push(s)
   Next
   DiffTime = Timer - StartTime
   Return Str(DiffTime * 1000) & " from short var in msec"

End

Private Sub myLongVar() As String

   Dim StartTime, DiffTime As Float
   Dim sVeryLongMyVariable As String = "test"

   StartTime = Timer
   For i As Integer = 0 To 1000000
     $aVariables.Push(sVeryLongMyVariable)
   Next
   DiffTime = Timer - StartTime
   Return Str(DiffTime * 1000) & " from long var in msec"

End
[code]

Gianluigi
