You are not allowed to know.
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).
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.
