title: String comma delimited to JsonArray
body: <p>I am using delphi xe7, win8.1</p>
  
  <p>My question is simple, but I am a newbie in Json.</p>
  
  <p>I have a comma delimited string to convert to JSONArray.</p>
  
  <pre><code>var s:string;
      ja:JSONArray;
  begin
  s:='a,b,c,d,e,f';//--&gt; can have many items comma delimited.
  ja:=JSONArray.Create;
  //???Convert string comma delimited to JSONArray
  ja:=ConvertStringDelimitedToJsonArray(s);
  end;
  </code></pre>
  
  <p>I´d like to know how to code the function ConvertStringDelimitedToJsonArray with a string as input parameter and output a JSONArray.</p>
  
  <p>Is there a delphi function to do it directly?</p>
