I'm not sure what you are trying, but here is some method howto make something.
Code:
#!/bin/ksh # or bash
# howto handle default value = user press return, nothing else
answer="y"
echo -e "Remove: (y/n): y\b\c"
read str
[ "$str" != "" ] && answer="$str"

# write something and make carriage return
echo -e "Your name\r\c"
read name

# write and remove
echo -e "Some\r\c"
sleep 2
echo -e "    \r\c"
sleep 1
echo -e "More\r\c"
sleep 1
echo
echo

#counter
i=10
echo -e "Cnt: \c"
while ((i<30))
do
     echo -e "$i\b\b\c"
     (( i+=1 ))
     sleep 1
done
echo

Using cursor something like:
Code:
clear
cat <<EOF
=========================================================
Screen test


EOF
loc0_0=$(tput cup 0 0)
bold=$(tput  smso)
boldoff=$(tput rmso)
save_loc=$(tput sc)
ret_loc=$(tput rc)

# after this init, use variable
echo "${bold}BoldText${boldoff} and not so bold"
echo -e "(Look line 0) Ask here:${save_loc}${loc0_0}LOCATION 0,0 IS HERE ***************${ret_loc}\c"
read answer
echo "${save_loc}${loc0_0}Your answer:$answer   ${ret_loc}"
echo 
echo "look line 0"
