title: "for" loop not working as per need
body: <p>I have following code:</p>
  
  <pre><code>set b=Hello
  set c=1
  set d=5
  for /l %%x in (1,1,%d%) do (set /a c=c+1 &amp; set "a=%a%%b%%c%")
  echo %a%
  </code></pre>
  
  <p>And for this, I wanted an output as:</p>
  
  <pre><code>Hello1Hello2Hello3Hello4Hello5
  </code></pre>
  
  <p>But instead, I get result as:</p>
  
  <pre><code>Hello1Hello1Hello1Hello1Hello1
  </code></pre>
  
  <p>Can anyone give me any idea on how can I do so?</p>
