Questions on AWK

Hi,
Could someone tell me how to use a varible in the one of the sections of the awk command below which adjusts the spacing (i.e. "%-5s%-10s%-15s")?

Code:

echo "1 2 3" | awk ' { printf("%-5s%-10s%-15s",$1,$2,$3); printf("\n"); } '

e.g. I have a variable named LENGTH which has the value 8 and I want to use this LENGTH variable in the "-10s%" section.

I tried specifying the varible with "-${LENGTH}s%" and "-$LENGTH\s%" but it did not work.

Any help will be greatly appreciated.

Steve
