title: concatenating a numeric with character
body: <pre><code>data test;
  name = 'abcdefgh';
  age = 30;
  res = name || age;
  run;
  </code></pre>
  
  <p>When I run the above code the variable res holds -> abcdefgh          30</p>
  
  <p>Why the numeric variable age is padding with blanks and then concatenated with the character variable?</p>
