[rest snipped] Sorry, Jean Louis, I can't understand what you are after. Even after reading you mail a couple of times. Sometimes (but I'm not sure either), I have the impression that you try to do too many things at once. Try to break them down into little pieces to give your interlocutors at least a small chance. You want to define a variable whose name you can only know at run time? Did I understand that correctly?
