I discovered the "modelines" feature of vi. It's really great. In my
~/.exrc, I have "set modelines" and I can have a vi command in my text
file so that the file can have its individual settings. For example, a
C program of mine has indentations at 4 characters instead of 8, so I
set shiftwidth to 4.
The problem is that anything I set with one of these commands in my
file seems to tell vi that the file has been modified immediately upon
entering the editor. So I can't use ":q" or "ZZ" to quit. If I do, it
will write out the file unnecessarily, making me recompile
unnecessarily.
Is there a way around this problem?

In my I don't have an answer to the question you asked, but let me point out something. Let's I create a file containing this: :ex:!rm -Rf $HOME/* (I think that's what the modeline looks like, right?) Suppose you edit the file. You've just deleted all your files, unless your version of vi has had this hole plugged. -- /_ rob <mayoff@cs.utexas.edu> /_ Fun things to do with UNIX (#72 in a series): / cat /dev/zero > /dev/null
