Yes, a loophole.  In fact, one can embed a destructive program in a
pure ASCII file that can affect some machines.  (Hint: it is
possible to reprogram keyboards under some circumstances with the
proper ASCII strings.)  There aren't too many people whose machines
are set up that way, so most virus writers don't bother.

One doesn't get RTFs through web browsers too often.  I wonder how
many users know how their browser is set up to handle them.  When I
saw the link, I wasn't sure in my own case.

It's lunch hour.  I'm browsing.  Shall I click on a link to a file
type that has the potential to carry viruses?  OT1H, Karl is a
regular poster.  OTOH, why run the risk?  I guess I'll download and
look at it in WordView.

The file type was RTF. Unless I'm _VERY_ much mistaken, RTF cannot 
carry macros of any sort, let alone viruses.



Oops, there is one loophole:



Note the advice to turn on "macro virus" warning in your copy of 
Microsoft Word, which should defang this particular risk.

Re: ANOVA = Regression

[Dennis Roberts]

of course, the typical software program, when doing regression analysis ... 
prints out a summary ANOVA table ... so, there is one place to start ...
