[racket] Newbie question - Drscheme hangs on directory-exists?

Oddly the search box didn't give me the answer yesterday (via Internet 
Explorer), but today it seems to work
after a delay.

As for examples, I think the more examples the better - one cannot have 
too many, if space allows. An example
can be worth a thousand words of explanation. I expect I am not alone in 
wanting to know what a programming
language or system is capable of in one's proposed area of use before 
deciding whether it is worth learning from
the ground up. Thus in this instance I missed the material on escaping.
