title: How to implement a try-catch block in scheme?
body: <p>I'm trying to implement a try-catch block in scheme using (call-cc) method but i'm not sure how it can be used for that. I could not find any example. </p>
  
  <p>And found examples contains just error-handling but what i want to do is: if an error occurred, the scheme program has to give a message to user (via display for-example) without suspending the program. </p>
  
  <p>Is that possible? </p>
