awk without printing newline

Question

I want the variable sum/NR to be printed side-by-side in each iteration. How do we avoid awk from printing newline in each iteration ? In my code a newline is printed by def

You can simply use ORS dynamically like this:

awk '{ORS="" ; print($1" "$2" "$3" "$4" "$5" "); ORS="\n"; print($6-=2*$6)}' file_in > file_out
