Right Margin and Auto Wrapping of lines

[KAP%OZ.AI.MIT.EDU@XX.LCS.MIT.EDU]

In certain library modules of (I hate to admit it) FORTRAN source
the statements are exactly 80 characters long. Emacs (I think un-
necessarily) auto wraps lines of length 80 characters. This is 
annoying since I get half as much text on the screen and all of it 
should fit. The lines look like this:


c THIS  IS A FORTRAN LINE                MODUL000!
1
C THIS IS ANOTHER                        MODUL000!
2
...


instead of:


c THIS  IS A FORTRAN LINE                MODUL0001
C THIS IS ANOTHER                        MODUL0002


Can I shut this off? Shouldn't EMACS be fixed so that it automatically 
wraps one character later?

Thanks,
