Subject: Re: Win32OLE: Output parameters, Dispatch IDs

I find it strange that the win32ole package cant handle out params.

Hunting in ObjectSpace with a semi-production script doesn't give me
the "warm and fuzzies".

Creating a basic .vbs file and calling it as such:
    pid = `cscript.exe exec.vbs`.split("\n")[3]
...works, but it's still a hack IMO.

Thanks again for the kind suggestions but since I'm still learning
ruby, knowing the precise problem or solution with this scenario would
be optimal.
