Frame frame = ....;

Instance instance = frame.addInstance(new Script(), 1, null, null);

GenericCommand command = new TickerCommand();
command.setInstance(instance);

command.addParameter("datasource", "{fileName}");
command.addParameter("stepsize", "8");
command.addParameter(....);
....

instance.setCommand(command);

...

FlashFile file = .....;
StandardContext context = new StandardContext();
context.setValue("fileName", "c:/somedir/somefile");
context.setValue("someOtherVariableName", "someOtherVariableValue");

file.processFile(context);

FlashOutput buffer = file.generate();
