title: Appending a string to each item of an array
body: <p>I have an array and when I try to append a string to it the array converts to a single string.</p>
  
  <p>I have the following data in an array:  </p>
  
  <pre><code>$Str  
  451 CAR,-3 ,7 ,10 ,0 ,3 , 20 ,Over: 41  
  452 DEN «,40.5,0,7,0,14, 21 ,  Cover: 4  
  </code></pre>
  
  <p>And I want to append the week of the game in this instance like this:</p>
  
  <pre><code>$Str = "Week"+$Week+$Str 
  </code></pre>
  
  <p>I get a single string:  </p>
  
  <pre><code>Week16101,NYG,42.5 ,3 ,10 ,3 ,3 , 19 ,Over 43 102,PHI,-  1,14,7,0,3, 24 ,  Cover 4 103,
  </code></pre>
  
  <p>Of course I'd like the append to occur on each row.</p>
