Whereas <a href="http://ncl.ucar.edu/Document/Functions/Built-in/addfile.shtml" target="_blank"><strong>addfile</strong></a> returns a reference to a single file in a
variable of type <b>file</b>, <strong>addfiles</strong> returns a variable
of type <b>list</b> that contains references, each of type <b>file</b>, to multiple files.
This combination of the <b>list</b> and <b>file</b> types forms a specialized <b>list</b> type. It
provides a means of obtaining the aggregated contents of variables that span the complete list of files. <p>
</p></li><li>2. It is not yet possible to use the file <b>list</b> type variable
as input to the "getfile<i>xxxx</i>" suite of functions. However, since each element of the
<b>list</b> is actually a <b>file</b> type variable, you can input a single element of
the <b>list</b> as an argument to any of these functions, e.g.:
<pre> files = <a href="http://ncl.ucar.edu/Document/Functions/Built-in/systemfunc.shtml" target="_blank"><strong>systemfunc</strong></a>("ls *.nc")
f = <strong>addfiles</strong>(files,"r")
