In the meantime I have found the answer in your older answers. Thank
you for all of them. The trick was to google for 'output' instead of
'reference' ;-)

In this case, using WIN32OLE::ARGS was enough to get what I need.

I have added a doc patch (7557) to ruby tracker to document that. (I
have copied pieces from your examples if you don't mind).

Thanks again.
