title: How to input to date format from a number
body: <p>I'm trying to put a number eg <code>20141001</code> into a date9. format eg <code>01OCT14</code>.
  I've tried to use the input function with an input format of <code>yymmddn8.</code> but SAS throws out 'informat could not be found or loaded'</p>
  
  <p>Any ideas how to get around this? (Sample code below)</p>
  
  <pre><code>data _null_;
    date=20141001;
    output=input(date,yymmddn8.);
    format output date9.;
    put output=;
  run;
  </code></pre>
