Text Processing Question

[LEWIS WILLIAM M JR]

See page 121 of Kernighan & Pike "The UNIX Programming Environment" for
an awk version of "double".

In my edition of the book there is an error in the program -- near the
end it reads:

		printf "double %s, ...
	if (NF > 0)			# <= DELETE ONLY THIS LINE
		lastword = NF
}' $*
