title: How does one manipulate arrays in crystal reports X?
body: <p>I was reading "Crystal Reports X - The complete reference" by G. Peck for a project at work, and I was wondering how one manipulates arrays in a Crystal Reports formula.  I could not find the answer easily in the book.  </p>
  
  <p>For instance - how do I do any/all of the following:</p>
  
  <p>-) create an array with a fixed number (say 10) of elements<br>
  -) create a dynamic array (whose size expands as needed)<br>
  -) get the size of the dynamic array<br>
  -) add and remove elements from the middle, beginning, and end of an array<br>
  -) empty an array  </p>
  
  <p>What is the most comprehensive resource/book for learning the Crystal Formula language syntax?  </p>
  
  <p>Thank you for any help you can provide.</p>
