      Valinda:
 
      I am not aware of any function or command to capture the active
fileref or filename, except there are functions like FILEREF, FILENAME
to check for the existence of any known fileref or filename.   Also
function like PATHNAME will list out the actual name of the external
file.
 
      However
 
     FILENAME _ALL_  LIST;
 
     will write all active filerefs to the SAS log.
 
    Hope this helps,
