Shell Programming and Scripting

Please forgive this newbie question. I have a need to create a script that asks a user for information. Something like:

What is the name: $NAME_TYPED_HERE

Is $NAME_TYPED_HERE Correct ? YES (NO would go back to -What is the Name-)

mkdir then goes on behind the scene and makes folder called $NAME_TYPED_HERE

Could someone point me in the right direction. I am familiar with shell scripting but have not really had to use variables. I am on Solaris.

Thanks

Code:

while :
do
     echo "Enter your directory name :"
     read dn
     echo "Your directory will be $dn , do you confirme y/n?"
     read ans
     case $ans in
          y) mkdir $dn && break ;;
          n) echo "$dn will not be created, try again" ;;
          *) echo "Wrong answer"; exit 1 ;;
     esac
done
