Thanks a lot to both ! it saved me. And sorry for late answer, i needed time
to test it.
By the way, is there a way to save the maxima command history into a file ?
i tried save("filename"); but it says that there was a writing error.
I'm using maxima under linux in console mode.
Thanks & Regards
Mocramis
