Ok, thanks for clarifying. But again, we are so used to dealing with ambiguity that we don't even notice it. It looks like the inputs/outputs are really nailed down....but still, it is ambiguous in countless ways. For example, you can type the input/output to these functions in any font or size you want. You don't have to use ASCII. The results on the screen can be glowing green phosphorus, red phosphorus, or a glorious retina display. etc etc. Wherever the specs end, the ambiguity begins.
