Sorry, no can do.  Not with a filename that was used to run gnuplot on, 
like that, anyway.  You can refer to environment variables, though, if 
your platform is sufficiently Unix-like to support command substitution:

	plot "`echo $FILE`.dat"

Or even move the entire scripting job off gnuplot's shoulders onto that 
of the shell, by using a "HERE" script:

	gnuplot -persist <<\EOF
	  plot "$1.dat"
	EOF


or the somewhat simpler

	echo plot "$1.dat" | gnuplot -persist
