Question Author
Fantastic. Thank you all so much. My wife and I were competing and I had it in my mind that con was synonamous with study but not sure. When I finished before her she capitulated and then asked me to parse the answer. I could parse the serve part but was not totally sure about Con. Thanks again all for confirming my suspicion.
BTW. She is mightily impressed with AB and the rapid response to this query at this time of night. I explained that this is the time the wise owls abound. :-)
