Opening a Batch tab via OLE automation

I want to open an .abb file using VBS but I don't know what OLE object governs batches.
Documents and AnalysisDocs don't work. Neither does Batches.
Anybody know?

You can run batch from command line

broker.exe /runbatch <path_to_abb_file>

Or you can run batch from AFL level:

ShellExecute("runbatch", "path_to_abb_file", "" );

There is no method to run ABB from OLE.
