title: Arrays, linked lists and other data structures in cmd.exe (batch) script
body: <p>I was playing with cmd.exe, but in its help I didn't find any info, how to define arrays.</p>
  
  <p>I have found, how to define simple variables:</p>
  
  <pre><code>set a=10
  echo %a%
  </code></pre>
  
  <p>But, I want to create arrays, linked list etc...</p>
  
  <p>So, does it able in cmd.exe ( I mean: does in cmd.exe exist any array keywords? )</p>
  
  <p>I want to realize some algorithms as:</p>
  
  <ul>
  <li>bubble sort</li>
  <li>quick sort</li>
  <li>gnome sort</li>
  </ul>
  
  <p>etc...</p>
  
  <p>So, I also want to know, does Cmd.exe have references or instances, structs etc?</p>
  
  <p>Cause its help not full in: /?</p>
  
  <p>Could Cmd.exe be defined as full by Turing-Machine definition? ( Turing-Complete )</p>
