-- PROGRAM STARTS HERE
-- All global code (outside of any functions) is first run.
-- Then the ScriptENGINE automatically run the State Machine by looking for the OnStateRun_[scriptName]() function.
-- If its not found (in this case it is), then the ScriptENGINE will look for the fallback function OnStateRun()
---------------------------
---------------------------
function OnStateRun_test1(param)
    -- Show the console window
    IApp:showConsoleWindow();

    -- Load options from file
    -- This already defined some options
    IApp:loadOptions('test.dat');

    -- Iterate over all options, and print them to the console
    print('--- PRINTING OPTIONS ---');
    IApp:forEachOption('OnIterateOptions');

    -- Set some new options
    print('--- Adding new options ---');
    IApp:setOptionInt('mysection', 'intData', 1234);
    IApp:setOptionBool('mysection', 'boolData', true);
    IApp:setOptionFloat('mysection', 'floatData', 987.654);
    IApp:setOption('mysection', 'stringData', 'abcdefg');

    -- Iterate over all options, and print them to the console
    print('--- PRINTING OPTIONS ---');
    IApp:forEachOption('OnIterateOptions');

    -- Wait for user input
    print('Press any key to exit...');
    IKey:getch();
end

-- Iterate all program options, and add items to the list

function OnIterateOptions(section, key, stringValue, userData)
    local str = string.format('[%s:%s] = %s', section, key, stringValue);
    print(str);
