Microstation Key-in: Attach Reference with live nesting


I am new to MicroStation V8i. I am trying to use a batch process to reference one file to a set a drawings. My issue lies in the script for the key-in.

This is what I have found so far:

Key-in: RF= [configuration_variable:]<filename> [,model_name] [,logical_name] [,description] [,view_name] [,scale] [,nesting] [,ON|OFF]

I'd appreciate any insight on how to use this command. I am not sure what entries are valid for each field. 

How would I use this command to reference a file with live nesting on and everything else as default?
