Not inside gnuplot.  But external tools can help, if you're doing this 
on a sane platform.  You'll have to write a little script (in awk, Perl 
sh or something like those, depending on your personal preferences) that 
does the extraction job, and prints the number to stdout:

	DP1=`your_tool your_file.dat`
