Qualifiers

/LOG
      /LOG
      /NOLOG

   Controls whether the DELETE command displays the file
   specification of each deleted file. The default is /NOLOG.


/SYSTEM
      /SYSTEM
      /NOSYSTEM

   Controls whether the DELETE command deletes files with the file
   type .SYS. Files with the type .SYS are usually necessary for
   the operation of an RT-11 system. Only RT-11 volumes handle .SYS
   files in this manner.

   The default is /NOSYSTEM; the DELETE command does not delete
   an RT-11 file with the .SYS type, whether matched by a wildcard
   specification or explicitly named. EXCHANGE displays a message
   whenever it skips a SYS file during a delete operation.


/VOLUME_FORMAT
      /VOLUME_FORMAT=option

   Defines the physical format of the volume to be processed. RT-
   11 volumes are the only volumes on which DELETE is currently
   supported.
