title: how to calculate percentile in SAS
body: <p>I want to calculate the 95th percentile of a distribution. I think I cannot use <code>proc means</code> because I need the value, while the output of <code>proc means</code> is a table. I have to use the percentile to filter the dataset and create another dataset with only the observations greater than the percentile.
  Clearly I don't want to use the numeric value..because I want to use it in a <code>macro</code>.</p>
