title: Search for specific character in alphanumeric string
body: <p>I have a string of characters that I need to search for the letter capital <code>P</code> from between six numerals, three on each side.  It's position can vary in the string, but will have the condition of six digits each time.  The digits will be 000 through 999 on both sides of the P.</p>
  
  <p>I want to find the numeric position in the string of the letter P for a formula.</p>
  
  <p>Here is a sample of the string: (Please notice that there are several capital P's to contend with.)</p>
