//          "Tech",
//          "Service"
//        ],
//        "viewable_for_sharing": true,
//        "eula_create_date": 1649108951523
//      }
//    ]
//  }

//  The destination is the empty "users" array, the source is the populated "users" array in jsonB.
jsonUsersDest := TChilkatJsonArray.Create(Self);
jsonA.AppendArray2('users',jsonUsersDest.ControlInterface);

jsonUsersSrc := TChilkatJsonArray.Create(Self);
jsonB.ArrayOf2('users',jsonUsersSrc.ControlInterface);

//  Copy the array items from source to dest
jsonUsersDest.AppendArrayItems(jsonUsersSrc.ControlInterface);

Memo1.Lines.Add(jsonA.Emit());

//  The end result is this:

//  {
//    "ciphertext": "encryptedData",
//    "status": 200,
//    "error": "errorMsg",
//    "users": [
