set directories with spaces

[Simon Lord]

How can we set the directory to a folder with spaces?  In the 
shell I would do the following:

cd "Mac OS X"

Under MetaCard I have to do the following which I would assume 
should work:

set the directory to "/"&quote&"Mac OS X"&quote

But that returns "can't open directory", am I missing a step?  
Anyone see an error in that script?

Sincerely,
Simon
