Charlie, Benoit,

Wouldn't something like that usually work?

PUBLIC SUB Main()
DIM col1 AS NEW Collection
DIM col2 AS NEW Collection
DIM sKey AS String
Dim Counter as Integer
 col1.Add("1", "one")
 col1.Add("2", "two")
 col1.Add("3", "three")
 col1.Add("4", "four")
 PRINT "Returns the key of the last read or last enumerated element. "
  FOR Counter = 0 to col1.Count
     sKey = col1[Counter].Key
     PRINT sKey & " = " & sElem
     col2.Add(sElem, sKey)
  NEXT
END

The documentation mentions that a Collection acts like a read/write array
so even though the workaround isn't very elegant, would it work?

Regards,
Dimitris
