begin
// This example requires Chilkat v9.5.0.63 or greater.

json := CkJsonObject_Create();
CkJsonObject_putEmitCompact(json,False);

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

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

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

CkJsonObject_UpdateString(json,'test.abc[0].xyz','Chicago Cubs are going to win the World Series!');
Memo1.Lines.Add(CkJsonObject__emit(json));

// {
//   "test": {
//     "abc": [
//       {
//         "xyz": "Chicago Cubs are going to win the World Series!"
//       }
