// declare a variable as a parameter
var s = new param;   // 定义时叫parameter


// issue a function call using the parameter
var o = output(dText.innerHTML, s, 'Hello, world.');

// the function is obviously designed to treat the 2nd argument as a parameter...
function output(arg1, arg2, arg3)  //在方法括号中接收参数的叫 argument 
{
  ...
  // ...so that eventually it can assign a value to it.
  arg2.setValue(a + b % 10);
  ...
}

// when ready to retrieve the output value, use the retrieval function.

dResult.innerHTML += s.getValue() + ' (' + o + ')';
