[Mediawiki-api] # of titles at once

[Eric Sun]

Hi,

According to the API documentation the "titles" argument can take a
list of titles,e.g.
http://en.wikipedia.org/w/api.php?titles=The_Matrix|Casablanca_%28film%29&action=query&export

Is there a limit on # of titles I can string together?
Would it be possible to combine a large number (say, 100 or 1000) into
one API request?

Thanks,
Eric
