Hello -
If I enter "(directory-exists? "C:\iconsource")" into DrRacket
I would expect it to answer with "#t" or "'#f" but in fact the
cursor goes to the next line, leaving an indent.
I am running this on Windows 7.
As a newbie I do not understand this behaviour.
You need to escape the backslash in your string:
(directory-exists? "C:\\iconsource")
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.
