title: how to simulate loop in turbo prolog
body: <p>I want to compute the summation of odd numbers in a given range like 1 to 9 is the given input. and my program will show the summation of all odd numbers between 1 to 9. Though the task is so simple theoriticaly, but as a starter of turbo prolog, I can't handle the loop to compute the summation. Any help would be appreciating..</p>
  
  <p>Advance thanks.</p>
