title: Can't define DQ and DT variable in Intel 8086 emulator
body: <p>I wanna to multiple 2 numbers,which have got 32bits.</p>
  
  <p>I can define DD for each variables,but I can't define DQ variables for result in emu8086.</p>
  
  <pre><code>data_seg segment
      X DD 12341234H
      Y DD 11111111H
      Z DQ ?
      data_seg ends</code></pre>
  
  <p>It will return error in line number 4,which declare Z as DQ .</p>
  
  <p>Can 8086 support DQ and DT type of variables?If it can,where is the problem?
  (I'm using emu8086 to emulate my assembly code)</p>
