Ok. Thanks again. I think I've found what I need.
(on lines of 'inpch' that contain 'TH' I change the field at position
$pos to be $new, preserving spacing made of 'space's and/or tabs).
If anyone comes up with sth. simpler...

Ruda

(The script is for 'rc', btw., so that the concatanation on the 3rd line work.)

	9 awk '
		/TH/ {n = split($0, spaces, /[^ 	]+/);
			$'$pos'='$new';
			line = "";
			for(i = 1; i < n; i++)
				line = line spaces[i] $(i);
			line = line spaces[n];
			print line;
			next;}
		{print}
		' inpch
