Re: How to run multiple instances of Writer simultaneously?

Thanks Matthew!

That’s close to what I’m using. However, would you mind sharing your “close document” code, as well 
as shutting down the soffice process?

In that context, it looks like you’re using the soffice process as the server? How about projects 
like listed in this question: https://forum.openoffice.org/en/forum/viewtopic.php?f=20&t=75523  
What about scalability as per this question:

Thank you,
Jens
