A classical example for scripting gnuplot from the outside.  E.g. if you 
choose the shell as the outside scripting language, something like the 
follow should do it:

for f in *.dat ; do
   out=`basename $f .dat`.png
   gnuplot <<\EOF
     set term png
     set out "$out"
     plot "z2.dat" u 1:4 w l lt 3, "$f" u 1:(6.6e-18*$2) w l lt 4
     unset out
EOF
done
