Method used to return a list with all parents that are not parameters. Even if the interactive Parent/children functionality can handle parameters, this method never returns parameters
let l (List)
let i (Integer)
let f (Feature)
l = `Geometrical Set.1\Line.3` ->ListParents()
i = 1
for i while i <= l->Size()
{
f = l.GetItem(i)
Message("", f.Name)
}
