title: Declare multiple variables with zero in one line
body: <p>In an old macro I declare many variables in one line like </p>
  
  <pre><code>Dim Jan_Bnm, Feb_Bnm, Mar_Bnm, Apr_Bnm, Mai_Bnm, Jun_Bnm, Jul_Bnm, Aug_Bnm, Sep_Bnm, Okt_Bnm, Nov_Bnm, Dez_Bnm
  </code></pre>
  
  <p>With this variables I make some calculations like</p>
  
  <pre><code>Jan_Bnm = Jan_Bnm + 1 
  'e.g. empty = empty + 1 -&gt; 1
  </code></pre>
  
  <p>Now I have the problem if the macro runs twice the old value is still stored</p>
  
  <pre><code>Jan_Bnm = Jan_Bnm + 1 
  '1 = 1 + 1 -&gt; 2
  </code></pre>
  
  <p>So all my values are doubled. </p>
  
  <p>Is it possible to set all variables by declaration to zero so that I don't have to set every (some hundreds) variable manualy?</p>
