EXPLAIN SECTION

STALIN
Type: Verb
Use:  STALIN allows the user to delete selected lines from the
      history file of an image or uv data set.  The lines may be
      deleted as specified, or the user may choose to review and
      confirm the deletions a line at a time.

      STALIN wworks with HI line numbers which may be determined
      using PRTHI.  The user is warned that, when lines are
      deleted, the line numbers change.  If you have a number of
      deletions to do, it is simpler to start with the highest
      numbered ones and work backwards.  If you don't, you
      should use PRTHI often to determine the new line numbers.
      If you have a lot of deletions to do, it may be easier to
      write the whole HI file to a text file with HITEXT.  Then
      edit the text file with your favorite editor.  Delete the
      old history with EXTDEST (INEXT='HI'; INVERS=1) or with
      STALIN (HISTART=1; HIEND=10000000) and then rebuild it with
      HINOTE (be sure that DOHIS = -1).
Adverbs:
  INNAME......Image name(name).   Standard defaults.
  INCLASS.....Image name(class).  Standard defaults.
  INSEQ.......Image name(seq. #).  0 => highest.
  INDISK......Disk drive # of image.  0 => any.
  HISTART.....Delete history records beginning with record
              HISTART.  0 => 1; larger than the max => error.
  HIEND.......Delete history records ending with record HIEND.  No
              default other than too large is set to the maximum in
              the file; HIEND < HISTART => error.
  DOCONFRM....> 0 => show each line in the range HISTART through
              HIEND and ask for confirmation before deleting it.
              A line is deleted only on Y or y.  If <= 0, the
              deletions happen silently.
