function chilkatExample() {

    var success = false;

    var json = new chilkat.JsonObject();

    success = json.LoadFile("qa_data/json/valuesAsNames.json");

    // Imagine we have JSON such as the following:

    // {
    //   "1680": {
    //     "entity_id": "1680",
    //     "type_id": "simple",
    //     "sku": "123"
    //   },
    //   "1701": {
    //     "entity_id": "1701",
    //     "type_id": "simple",
    //     "sku": "456"
    //   }
    // }
    // 

    // This presents a parsing problem because the member names, such as "1680"
    // are not keywords.  Instead they are data values.  We don't know what they
    // may be in advance.  

    // To solve, we iterate over the members, get the name of each, ...
    var numMembers = json.Size;
    var i;
    for (i = 0; i <= numMembers - 1; i++) {

        var name = json.NameAt(i);

        console.log(name + ":");
        // jRecord: JsonObject
        var jRecord = json.ObjectAt(i);

        console.log("entity_id: " + jRecord.StringOf("entity_id"));
        console.log("type_id: " + jRecord.StringOf("type_id"));
        console.log("sku: " + jRecord.StringOf("sku"));
