Sorry Erik, I think you'll have problems with big files.  At least
we would because our 'tail' has a bug: if the line number is > 99,
strange things happen.  To test, try:  "tail -nnn bigfile | wc -l"
And, you've got the same Un*x port that we do...Un*Plus+.
(Let's both report it!)

Ah!, but along the lines of your suggestion there *is* a solution!
I've had good luck using 'sed' instead of the 'head'/'tail' combination.
It's fast and flexible.  Try a varient of this:

	x=3
	oneline=`sed -n $x,"$x"p`
	echo $oneline
