  29     INPUTS
  30         DRAWER          -- initial content of drawer field
  31         FILE            -- initial content of file field
  32         PATTERN         -- content of pattern field (e.g. #?.c)
  33         TITLE           -- title of the dialog box
  34         POSITIVE        -- string for the left button
  35         NEGATIVE        -- string for the right button
  36         ACCEPTPATTERN   -- only files which match the pattern are displayed
  37         REJECTPATTERN   -- files which match the pattern aren't displayed
  38         SAVEMODE        -- requester is displayed as save requester
  39         MULTISELECT     -- more than one file can be selected
  40         DRAWERSONLY     -- only drawers are displayed
  41         NOICONS         -- no icon files (#?.info) are displayed
  42         PUBSCREEN       -- requester is opened on the given public screen
  43         INITIALVOLUMES  -- shows the volumes
