  usernm VARCHAR2(80) := 'anonymous';
  passwd VARCHAR2(80) := '';
BEGIN
  fid := fclient_p.createFTPClient;
  fclient_p.login(fid, host, usernm, passwd);

  fclient_p.help(fid);
  DBMS_OUTPUT.PUT_LINE(SUBSTR(REPLACE(fclient_p.getLastResponseString(fid), CHR(10)), 1, 255));

  fclient_p.logout(fid);
  fclient_p.remove(fid);
