title: Byte comparation
body: <p>I'm work on a simple Assembly code, but, I got that erro:</p>
  
  <blockquote>
    <p>test.asm:30: error: comma, colon or end of line expected</p>
  </blockquote>
  
  <p>Ok, in the line 30 I have this code:</p>
  
  <pre><code>cmp byte ptr [129],0    ;anything in the line segment? 
  </code></pre>
  
  <p>OK.. I tried this:</p>
  
  <pre><code>mov [direct_segment],ax ;segment for Direct information
  cmp byte ptr [ax+4],0    ;anything in the line segment?  
  </code></pre>
  
  <p>Ok, but, the error is the same :(</p>
  
  <p>How I can solve this ???</p>
