Com Interface and Rhino.Command

Helo,
I have two questions:
Access Rhino through Com as “Interface” method, if multiple Rhino processes are running, which process Rhino.Interface is accessed ?

What is correct syntax Rhino.Command whitch option “_-” or " -_" ? (In examples I see both)

Thanks

COM does not provide provisions to specify which instance to hook onto. Basically, you are going to get the first instance that COM finds.

Either order works. The ‘_’ character tells Rhino to run the English version of the command. The ‘-’ tell Rhino to run the command in script mode.
