Try

#!/bin/csh
if (0) then
cat << HETE; else; HERE
else
echo There
endif

	I don't particularly like writing shell script for C shell for the
very reason that I can never tell what kind of "weirdness" would
pop up where I least expected it.

	Oh, BTW, in my personal opinion, I would say that the Korn shell is
"somewhat" better than the C shell.
