VMS Help DTM, DELETE, HISTORY  *Conan The Librarian (sorry for the slow response - running on an old VAX)

   Deletes history information from the history file.

   Format

     DELETE HISTORY  [/qualifier...] "remark"

1 - Command Qualifiers

 1.1 - /BEFORE

   /BEFORE=time

   Deletes all history information from the history file dated prior
   to the specified date. The deleted information is replaced by a
   single entry stating that history information has been deleted
   from the history file.

   If you omit the /BEFORE qualifier, the default is to remove
   information that was logged prior to the time you enter the
   command. If you include the /BEFORE qualifier and do not specify a
   time, the default is TODAY.

   You can specify the time as an absolute, delta, or combination
   time value, or as one of the following keywords: TODAY, TOMORROW,
   or YESTERDAY. Digital Test Manager interprets TOMORROW as the time at
   which you enter the DELETE HISTORY command.

 1.2 - /CONFIRM

   /CONFIRM (D)
   /NOCONFIRM

   Controls whether Digital Test Manager prompts you to confirm each
   deletion. Valid responses are Yes, No, All, or Quit.

 1.3 - /LOG

   /LOG (D)
   /NOLOG

   Controls whether Digital Test Manager displays informational and
   success messages on your screen.

 1.4 - /OUTPUT

   /OUTPUT[=file-specification]

   Sends output from the DELETE HISTORY command to the specified
   file.

   The output is written to a file called HISTORY.OUT in your
   current directory if you do not specify the /OUTPUT qualifier.
   If you specify the file name without the file type, the file type
   defaults to .LIS.

2 - Example

   DTM> DELETE HISTORY /BEFORE=08-JAN "Deleting old information"
   Confirm DELETE HISTORY/BEFORE=8-Jan-1998 [Y/N] (N): Y
   %DTM-S-HISTDEL, 150 history records deleted
   DTM>

   This example deletes all history records in the history file
   recorded before January 8, 1998. The deleted information is
   replaced with the following record:

   * 8-JAN-1998  00:00:00 SMITH REMARK  "PREVIOUS HISTORY DELETED"
