	thanks;  you were right on the money. 

	i think that by doing a

	grep -v "^$" <<file[s]>>

	all blank lines are scotched.  in this perl script, the syntax
	didn't catch my eye.   at least that's my excuse... .

	anyway, axeing that line did the trick; now i can chapterize
	my book from the huge text file.

	gary

	PS: is there any one-liner to add back one newline between
	paragraphs?
