Shell Programming and Scripting

I'm new to the script programming and I have this piece of code (repeatedly used) in my program:

while :
do
................
ans=`ckyorn -p "Do you want to continue?"`
if [ "$ans" = "n" ] || [ "$ans" = "no" ] || [ "$ans" = "N" ] || [ "$ans" = "NO" ]; then
break
elif [ "$ans" = "q" ] || [ "$ans" = "Q" ]; then
echo "Aborting..."
exit 2 # exit code for user choice of aborting
fi
done

It works fine but I wonder if there is a simpler way to write the if block- without detailing each of the conditions. I'm sure there is but don't know what;-)
Any advice woulld be highly appreciated. Thanks in advance!!

you could use case .... esac

Code:

case `cykorn ....`
y | yes )
     do yes thing
     ;;
n | no )
     do no thing
      ;;
* )
     echo what?
     ;;
esac

...exactly what I wanted.
