title: Cannot find any information on what [ds:0x18] refers to in the NASM documentation
body: <blockquote>
    <p>Cannot find any information on what the instruction <code>mov eax, [ds:0x18]</code> does in the NASM documentation.</p>
  </blockquote>
  
  <p>Looking through the NASM documentation it's not written what the semantics of <code>[ds:0x18]</code> is, except that it is valid syntax for effective addressing.</p>
  
  <p>Can someone clarify the function of this syntax, and if possible refer to a place in the documentation where its semantics is given implicitly?</p>
