so can i have something like this?

Code:

if [[ "$letter" < Z  || "$letter" == Z && "$letter" > A || "$letter" == A ]]; then

EDIT:

Code:

"3")
clear
echo Enter capitol alphabetical letters one at a time and press 0 to finish
letter="Z"
if [[ "$letter" < Z || "$letter" == Z ]] && [[ "$letter" > A || "$letter" == A ]]; then
        while [[ "$letter" == Z || "$letter" < Z ]] && [[ "$letter" > A || "$letter" == A ]] && [[ "$letter" != 0 ]]; do
        read letter2
                if [[ $letter2 < $letter ]]; then
                letter=letter2
                else
                break
                fi
        break
        done
elif [ "$letter2" == 0 ]; then
echo Lowest letter is $letter
else
echo "Invalid input. Please enter A-Z (capital) one at a time finalised by a 0"
fi
;;

ive changed the code a bit more to make it like this. No errors occurs. However when i run the script it will ask for input and afterwards break out of all loops and end the program returning to the menu. What have i done wrong?
