Thanks for all the many replies. Everyone agreed that coke is gluten
free.  What was very interesting for me was that so many people said it
upset their stomachs like it did mine.  However, one kind person pointed
out that that caramel in coke is make from corn.  This explains a lot as
I seem to have a strong sensitivity to corn.  One more thing to cross
off my list of goodies.
