Remove the colored read command
Code:
#! /usr/bin/ksh
echo "This program is designed to do measurement conversion"
echo "Enter yard"
read yard
echo "The result in feet is:"
expr $yard '*' 3
echo "Do you want to convert from feet to yard as well?"
echo "Please enter your answer"
echo "please enter yes to continue or no to exit:"
read
while true
do
printf "%s " " Enter feet?"
read feet
echo "The result in yard is:"
expr $feet / 3
read continue
case $continue in
[yy]*) ;;
*) printf "%s\n" "Good-bye"
break
;;
esac
done

By removing read, I defeat the purpose. I no longer have the option of asking the user what he/she wants to do. What if the user does not want to continue.

Do you mean that you want to ask user to continue or not for conversion from feet to yard at the first time? Then you should have used some variable to capture that input from the user.
Code:
#! /usr/bin/ksh
echo "This program is designed to do measurement conversion"
echo "Enter yard"
read yard
echo "The result in feet is:"
expr $yard '*' 3
echo "Do you want to convert from feet to yard as well?"
echo "Please enter your answer"
echo "please enter yes to continue or no to exit:"
read continue
while true
do
case $continue in
[yy]*) ;;
*) printf "%s\n" "Good-bye"
break
;;
esac
printf "%s " " Enter feet?"
read feet
echo "The result in yard is:"
expr $feet / 3
echo "please enter yes to continue or no to exit:"
read continue
done

I modified it to make it work. See below.

But if someone can still find a way to use th eif statement, please let me know.





#! /usr/bin/ksh
echo "This program is designed to do measurement conversion"
echo "Enter yard"
read yard
echo "The result in feet is:"
expr $yard '*' 3
echo "Do you want to convert from feet to yard as well?"
echo "Please enter your answer"
echo "please enter yes only if you wish to continue:"
echo "Otherwise Press Ctrl C to exit:"read
while true
do
printf "%s " " Enter feet?"
read feet
echo "The result in yard is:"
expr $feet / 3
read continue
case $continue in
[yy]*) ;;
*) printf "%s\n" "Good-bye"
break
;;
esac
done
