Then I think you found the very thing I needed... Thank you !!! :-) I do not need 1 millions variables, but clearly I do not want the computations to be too slow under 10000.. If I have something like 1000 variables, I very often have 5000 or more functions to define and work on, so I need the symbolic expression to be handled easily by Sage !
