At least two things did go wrong, actually.  First, you didn't notice 
that I had assumed your data files are called *.dat, whereas yours are 
actually called *.asc.

And there are $2 in here, but no $1.  But there should be.

Second shot, this time in a single construct, which you can either type 
in verbatim or save as a script file:

for f in *.asc.gz ; do
   gif_file=`basename $f .asc.gz`.gif

   gnuplot <<EOF
     set term gif ; set output "$gif_file"
     plot "< gzcat $f" using 3:4 with dots
     unset output
EOF
done
