VMS Help NCS Command, Command Qualifiers, /HISTORY  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  /HISTORY

   Use this qualifier with  the  /LIST  qualifier  to  list  the  update
   history record headers for  the NCS library in the following format:

        username operation n modules on dd-mmm-yyy hh:mm:ss

   The  operation  may  be  a  replacement,  insertion,  or deletion of
   definition modules.  For  example,  a  history  record  header might
   state:

        JONES  deleted   6 modules  on  23-JAN-1987 16:00:00

   If you include the /FULL qualifier together with  the  /HISTORY  and
   /LIST qualifiers, NCS  lists  the  history  record  headers for each
   update.
