Qualifiers

/APPEND
   Controls whether CMS appends the command output to an existing
   file, or creates a new file. If you specify /APPEND and the output
   file does not exist, CMS creates a new file. If you do not provide
   an output file specification (see the description for /OUTPUT),
   the output is appended to SYS$OUTPUT.

/BEFORE=date-time
   Lists all history information prior to a specified date. By
   default, the time is the current date and time. The time value
   can be an absolute, delta, or combination time value, or one of
   the following keywords: TODAY, TOMORROW, or YESTERDAY.

/OCCLUDE[=option,...]
   Controls whether CMS selects the first instance of the specified
   object, or all instances of the specified object in the library
   search list. The options field contains one or more keywords
   associated with the name of the object. The options field can
   contain the following keywords:

      ALL--equivalent to OTHER
      OTHER (D)
      NOOTHER
      NONE--equivalent to NOOTHER

   You can specify either ALL, NONE, or the [NO]OTHER keyword.

   By default, CMS performs occlusion for all objects; that is, CMS
   selects only the first occurrence of a specified object.

/OUTPUT[=file-specification]
   Directs CMS to write output to the specified file, except for any
   warning and error messages, which are written to SYS$OUTPUT and
   SYS$ERROR. CMS creates a new file if you do not specify /APPEND.
   If you omit the /OUTPUT qualifier (or if you specify /OUTPUT
   but do not provide a file specification), CMS directs output to
   the default output device (SYS$OUTPUT). If you omit either the
   file name or the file type component, CMS supplies the missing
   component from the default specification.

/SINCE=date-time
   Specifies that only those history entries dated on or after the
   given time are to be displayed. The time value can be an absolute,
   delta, or combination time value, or one of the following
   keywords: TODAY, TOMORROW, or YESTERDAY. When the /SINCE qualifier
   is omitted, all transactions that occurred since the library was
   created are displayed. If you specify the /SINCE qualifier but do
   not specify a value, CMS defaults to /SINCE=TODAY.

/TRANSACTIONS=(keyword,...)/NOTRANSACTIONS=(keyword,...)
   Displays all transaction records generated by a specific command.
   You can specify the following keywords with this qualifier:

   ACCEPT   FETCH     REMOVE
   ALL      INSERT    REPLACE
   CANCEL   MARK      RESERVE
   COPY     MODIFY    REVIEW
   CREATE   REJECT    SET
   DELETE   REMARK    UNRESERVE
                      VERIFY

   If you specify more than one keyword, you must enclose the keyword
   list in parentheses. The /TRANSACTIONS qualifier directs CMS
   to list transaction records for only the listed keywords. The
   /NOTRANSACTIONS qualifier directs CMS to list transaction records
   for all keywords except the listed keywords.

/UNUSUAL
   Controls whether transactions recorded as unusual occurrences
   are displayed. If you specify /UNUSUAL, only unusual transactions
   are displayed. By default, /NOUNUSUAL displays all transactions,
   including unusual occurrences. The following CMS transactions are
   defined as unusual occurrences:

   o  A RESERVE command specifying an element that is already
      reserved
   o  A concurrent replacement
   o  A VERIFY/RECOVER command
   o  A VERIFY/REPAIR command
   o  A CONVERT LIBRARY command
   o  A REMARK/UNUSUAL command

/USER=username
   Lists the transactions executed by the specified user.
