 rc = filename(fref);
 end;
 else

 length msg $200.;
 msg = sysmsg();
 put msg=;
 did = .;
 end;
 if did <= 0
 then
 putlog 'ERR' 'OR: Unable to open directory.';
 dnum = dnum(did);
 do i = 1 to dnum;

 /* If this entry is a file, then output. */
 fid = mopen(did, filename);

I tried your code in SAS OnDemand for Academics and it outputs a file list.

Are you specifying the directory path correctly?

  rc = filename(fref, '/home/myusername/');/* specify "path of folder/subfolder" */

It is strange that you get no results at all, so please paste the log after submitting.

At the end of path I didn't give the "/" previously. That's why i didn't get the output. Now am getting output. Thank you.
