The Undelete command recovers deleted files. It is done as safely as
 possible. If undelete discovers that the file header or blocks of the
 deleted file have been reused, the undelete process will stop.
 The /FILE, /IDENTIFIER or /OWNER qualifier can be used to select specific
 files. The /LIST qualifier can be used to generate a list of recoverable
 files without actually undeleting files.

 If a matching filename is found undelete will ask for a confirmation
 before undeleting the file. Multiple files can be undeleted with
 just one UNDELETE command. After a succesful undelete the file will
 be entered in the original directory if possible or in the
 [SYSLOST] directory.

 NOTE: The volume (set) will be locked for other users during the
 undelete command unless the /LIST qualifier is used.

 Syntax:
