title: How to get the nth character of string in Postscript
body: <p>I`m new to Postscript, and I was wondering how to get the nth character of a string in postscript.</p>
  <p>If I do something like</p>
  <p><code>(hello) 1 get</code></p>
  <p>then 101 is pushed on the stack (ASCII 101 corresponds to &quot;e&quot;)</p>
  <p>how to convert that 101 to the corresponding &quot;e&quot; character as string (e)?</p>
  <p>or how to compare it to a string (e) such that i can tell it is in fact some char 'e'?</p>
  <p>so how to say something like
  101 === (e) ?</p>
