The User's Reference Manual, once referred to on this net as the "NeXT Useless Reference Manual," should have been inside the 1.0 upgrade box. I haven't been able to find an online version, but it is similar in scope to the "User Manuals Release 0.9." Perhaps you should check with whoever upgraded your NeXT. >2. I can't su to root. In contradiction to the man page on su, I am not >prompted for a password. Instead, I get the message "You do not have >permission to su root." I think you have to be part of the "wheel" group. Change your group affiliation to "wheel" (gid = 0) AND add your name to the "wheel" group. Both can be done with the NetInfoManager application. >3. How do I change a file's application?

Try changing the name 'fname' to 'fname.ma' The '.ma' suffix seems to link that file to Mathematica. I don't know if cell formating will be preserved or if the notebook can be evaluated; I haven't really tried this myself.
