title: What does od mean in mean in pseudo-code?
body: <p>My lecturer has presented me with the following pseudo-code: </p>
  
  <pre><code>at each timer interrupt
  do
  
  • perform analog-to-digital
  conversion to get y;
  
  • compute control output u;
  
  • output u and do digital-to-analog conversion;
  
  od
  </code></pre>
  
  <p>I am wondering what <code>od</code> could mean in this context?</p>
  
  <p>Maybe it is part of the programming language I am not aware of? </p>
