DOPTNAME works only if the directory was previously opened by the DOPEN function. The names and nature of directory information items vary depending on the operating system. The number of attributes that are available for a directory also varies depending on the operating system.

Example

Open the directory identified by the fileref MYDIR, retrieve all system-dependent directory information items, write them to the SAS log, and then close the directory:

   /* Assign the fileref MYDIR to the  */
   /* filename stored in the variable DIRNAME   */
   /* and open it.                              */
rc=filename('mydir',dirname);
dirid=dopen('mydir');
numitems=doptnum(dirid);
do j=1 to numitems;
   opt=doptname(dirid,j);
   put 'Directory information=' opt;
end;
rc=dclose(dirid);
