- I have also seen "0" (in tarot cards and many other places (including some clocks), although I don't like the label of "0" for the Fool/Excuse because that card doesn't have a value of zero) and "NIHIL". --Zzo38 (talk) 05:34, 14 October 2013 (UTC)
Peek or pop?
For most instructions it isn't clear if the values are removed from the stack or not. I think it would be nice to add a third column in the instruction table showing the stack before and after the operation. Of course that wouldn't be very verbose ;-) --Koen (talk) 23:10, 13 October 2013 (UTC)
