Stallie - can't help you with the query, other than the points already raised (some of which were news to me, but I don't got one of them new-fangled gizmos anyway) and the obvious cross reference to the Ops Man for the Operator; but just curious (given your recent plethora of technical q's) are you lining up for an interview with someone......? Best wishes if so......hell of a commute though.....?
