my objection to marking cards is based on my assumption that such logic essentially "touches" every card in the stack.
Frank, et al:
Perhaps I am incorrect here, in that if the engine maintains an index of marked cards, "unmark all cards" can simply empty the index, rather than set a property on each card. But the Transcript Dictionary lists "mark" as a card property; so that leads me to assume "mark [or unmark] all cards" sets the property on each card.
I'd need to do some timing tests to get beyond idle conjecture; but if forced to bet, my money is on mark/unmark all cards touching every card in a stack.
