Hello
Many thanks.
Perhaps where "directory-exists?" is explained in the documentation,
there should also be a pointer
to an explanation what to substitute for the place-holder "path" (in
italic). This would mention the need
to escape the backslash, which to a newbie like myself is not obvious.
Or an example could be given,
which would show the escaping backslash.
I haven't really found my way round the documentation yet. I find that
if I want to look up "directory-exists?"
using Google in Mozilla Firefox is the best way.
Regards

DrRacket colors the bad string red to indicate that there's a
problem with it. If you insert the extra backslash, it turns green.
Wouldn't it be nice for DrRacket to signal an error when you hit
enter instead? Yes, but it strikes me as a subtle problem. (We do,
after all, want to permit multi-line repl entries.) I'll let someone
who's thought about it more address that part.
(Funny coincidence: it's been doing what it does now for a while, and
recently I suggested changing things so the read error will be
reported instead of waiting for you to fix it.)
