title: How to take user input in scheme and use it
body: <p>I'm making a program in Scheme that needs to take user input in the form of numbers. It then uses these numbers to do basic comparisons and make decisions. I can find a number of lists of procedures, but I can't seem to figure out what to do.</p>
  
  <p>I've used (read-char) and (peek-char) so far. They both return #\1 instead of a number. I tried to find a way to convert that, but can find nothing yet.</p>
