Case inside While read File

Hi Experts,

Need your guidance for case statement. I tried many way but no success yet.Now my existing code is doing something like below. Each Line of the input file contains one test case.
Code:
#!/bin/bash
FILE=$1
while read LINE; do
     do COMMAND
done < $FILE

Now I want to modify the code so that it will ask for User Input to continue or not with the next line/next test case. If only YES it process the next Line from Input file else Exit .

I tried with below code but unfortunately it iterates infinitely. Please guide.
Code:
while read -r line
do 
 echo $line
  while true; do
    read -r -p "Do you wish to continue?[y/n]" yn
    case $yn in
        [Yy] ) do COMMAND; break;;
        [Nn] ) exit;;
        * ) echo "Please answer yes or no.";;
    esac
  done
    
  echo "Processing the Next line"
    
done < $1

BR,
PD

NAME
ratfor - rational Fortran dialect SYNOPSIS
ratfor [ option ... ] [ filename ... ] DESCRIPTION
Ratfor converts a rational dialect of Fortran into ordinary irrational Fortran. Ratfor provides control flow constructs essentially iden- tical to those in C: statement grouping: { statement; statement; statement } decision-making: if (condition) statement [ else statement ] switch (integer value) { case integer: statement ... [ default: ] statement } loops: while (condition) statement for (expression; condition; expression) statement do limits statement repeat statement [ until (condition) ] break [n] next [n] and some syntactic sugar to make programs easier to read and write: free form input: multiple statements/line; automatic continuation comments: # this is a comment translation of relationals: >, >=, etc., become .GT., .GE., etc. return (expression) returns expression to caller from function define: define name replacement include: include filename The option -h causes quoted strings to be turned into 27H constructs. -C copies comments to the output, and attempts to format it neatly. Normally, continuation lines are marked with a & in column 1; the option -6x makes the continuation character x and places it in column 6. Ratfor is best used with f77(1). SEE ALSO
