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. --

Hi Rob,
Just ran a little test. Made a stack with 10000 cards with 1 field (fld 1) on each. Put some text on random cards. Put some extra fields (fld 2) on some of the cards
on mousup put the long secs into zap -- ;-) mark cards where field 1 contains <sometext> put the long secs - zap end mouseup
results around 10.420514
mark cards where field 2 contains <sometext>
results around 0.072319 (on tibook 400 mhz )
Seems to me that the mark/unmark command doesn't touch every card in the stack. Can we force a bet? :-))
Greetings, WA
