$ help type /tail

TYPE

   /TAIL

         /TAIL[=n]

      Displays the last several lines of a log file. The value, n,
      defaults to p-2 where p is the current terminal page length. You
      can use TYPE/TAIL only if all of the following criteria are true:

      o  File organization is sequential.

      o  The longest record is less than 512 bytes.

      o  The record format is either VAR, VFC, STM, STRCM or STMLF
         (for more information, see the description of FAB$B_RFM in the
         OpenVMS Record Management Services Reference Manual).

      o  The file being typed is on a device that supports random
         access. The TYPE/TAIL command does not work on magnetic tape
         drives.

      Even with this criteria, some file conditions cannot be
      anticipated and may not allow display of the last several lines
      of a log file, resulting in the following error message:

      %TYPE-W-READERR, error reading DEVICE:[DIRECTORY]FILE.EXT;1
      -SYSTEM-E-UNSUPPORTED, unsupported operation or function
