Hello everybody.
I've got a new problem.
I need to insert roman characters in some formulas instead of
Italic/emphatized. I tried:
1) C-m, to activate mathed;
2) click on the button for the TeX mode;
3) \textrm{H} if I need H, for istance.All this seems to work fine, because I can have Xdvi running and I can see its output just as I would like. But after saving my file and closing it, when I open it again all the formulas in which I adopted this method, and only they, have disappeared ! Can someone be so kind as to tell me how can I have roman characters in my formulas in a safe way? thanks Carlo
