function chilkatExample() {

    var success = false;

    var bd = new chilkat.BinData();

    //  This example will load a PDF and return it as a base64 string.
    success = bd.LoadFile("qa_data/pdf/helloWorld.pdf");
    if (success !== true) {
        console.log("Failed to load file.");
        return;
    }

    var b64Str = bd.GetEncoded("base64");
    console.log(b64Str);

    //  Now write the base64 string back to the binary PDF file:
    var bd2 = new chilkat.BinData();
    success = bd2.AppendEncoded(b64Str,"base64");
    success = bd2.WriteFile("qa_output/helloWorld.pdf");
