"Hello")
>>>
</pre>

As you can see, no result came back from the function.  This is because
win32com has no type information available to use, so doesn't know the
parameter should be passed as a <code>byref</code> parameter.  To work
around this, we can use the <code>VARIANT</code> object.

<p>The following example explicitly creates a VARIANT object with a
variant type of a byref string and a value 'Hello'.  After making the
call with this VARIANT the value is updated.
