limit for addfiles function ?

Hi I tried using the ncl addfiles fuction. The files I am trying to extract
data from are wrf files, but that shouldn't matter. Of course there are many
wrfout files because the model spits out a file every hour or every 3
hours..
When I try to use the addfiles function, NCL gives back the error that there
are "too many files."

So the addfiles function has a limit? Is there a way around this? Kind of a
show stopper for this function...
