exit=9
until [ "$answer" = $exit"] ; do

echo -e "\n Welcome to Danny's Main Menu \n"
echo "1 -- users"
echo "2 -- Calender for Desired Month and Year"
echo "3 -- Current Directory Path"
echo "4 -- Change Directory"
echo "5 -- Long Listing of Visible Files in the Current Directory"
echo "6 -- Current Date and Time"
echo "7 -- Start Vi editor"
echo "8 -- E-mail a file to a user"
echo "9 -- quit"
echo -e "Make your selection:\c"

read answer
echo
case "$answer" in

1) user
;;
2) cal
;;
3) path
;;
4) cd
;;
5) ls -f | more
;;
6) date
;;
7) vi
;;
8) mail -s
;;
9) exit
;;
*) echo "There is no selection:$answer"
;;
esac

Missing " before $exit
until [ "$answer" = "$exit"] ; do
.
.
.
esac
done

I added the " as you had said to and I get the same response. Any ideas?

You got to start paying attention to detail or you are not going to make it.
