// The UpdateString method updates or adds a string member.
// It also auto-creates the objects and/or arrays that
// are missing.  For example:
json.UpdateString('test.abc[0].xyz','Chicago Cubs');

// The JSON now contains:
Memo1.Lines.Add(json.Emit());

// {
//   "test": {
//     "abc": [
//       {
//         "xyz": "Chicago Cubs"
//       }

json.UpdateString('test.abc[0].xyz','Chicago Cubs are going to win the World Series!');
