Hi Everyone, What I usually do if I receive an email query whose answer could apply to the whole, is reply to the sender and then post the answer as a FAQ. Here is the first.

"I saw there are 2 spaces in some of your examples in the document, should I also keep this format in my command program?"

More generally, will differences in the format matter?

Don’t worry. We will be using automated testing, not automated marking. That is, the marking will be done by humans who can see that the two answers basically say the same thing. The precise words also don't matter, except where it becomes ambiguous or the meaning is changed. Fair enough?
