"Specify the reference angle <0>" takes a typed angle or two points; "Specify the new angle or [Points] <0>" takes a typed angle, a point measured from the base point, or two points after `P`. The objects turn by the new angle minus the reference angle. Previously Reference only said "not available yet" and the values that followed were misread or run as commands.
