That's useless use of 'cat'.

	gnuplot >$OUT <<EOF

would work just as well, and without running yet another program.

The problem is not with gnuplot, but with csh.  You have to figure out 
what kind of quoting you need to get a literal '$' character into the 
text generated by the HERE script in csh.  Or, if you can't get that to 
work, see 'help column'.
