title: Value in Carry Flag
body: <p>If I do the following (where <code>cx</code> has 0b1011 or 11 in decimal prior to the shift):</p>
  
  <pre><code> shl cx, 1
  </code></pre>
  
  <p>After <code>shl</code>, the carry flag should be set. As <code>shl</code> will move 0b1011 to 0b0110 and 1 will be in <code>CF</code>. </p>
  
  <p>My question is: how do I access the value in the carry flag? Let's say I want to append it to register <code>bx</code>, obviously <code>mov bx, cf</code> does not work so how would you go about doing that?</p>
