title: If / Else statement, how to say "DoNothing" or "Continue"
body: <p>I have an IF / ELSE statement, although I would like to know how to tell the "else" part to do nothing if it is true. e.g.:</p>
  
  <pre><code>if(x == x) 
   //run calc.exe
  
  else
  //DoNothing
  </code></pre>
  
  <p>Or I am write in saying that if I just remove the else statement, it will continue anyway if the if condition is not matched?</p>
