VMS Help CMS, UNRESERVE, Qualifiers  *Conan The Librarian (sorry for the slow response - running on an old VAX)

1 - /CONFIRM

    Controls whether CMS prompts you for confirmation before each
    transaction.

    When you specify /CONFIRM and run CMS in interactive mode, CMS
    prompts you for confirmation. If you type YES, ALL, TRUE, or 1,
    CMS executes the transaction.  If you type NO, QUIT, FALSE, 0,
    or press RETURN or CTRL/Z, no action is performed. If you type
    any other character, CMS continues to prompt until you type an
    acceptable response.

    CMS does not prompt for confirmation in batch mode.

    The /NOCONFIRM qualifier does not override the confirmation prompt
    issued when you unreserve a concurrent reservation or when you
    cancel another user's reservation.

2 - /DELETE[=file-specification]

    Controls whether all versions of the unreserved file are deleted.
    If you omit /DELETE, the files are not deleted. If you specify
    /DELETE without a file specification, all versions of the
    unreserved files are deleted from your current directory. The
    file specification allows you to specify a different location and
    the name of the file to be deleted.

3 - /GENERATION=generation-expression

    Specifies which reserved generation of the element is to be
    unreserved. If you have more than one reservation of the same
    element generation, you must use the /IDENTIFICATION_NUMBER
    qualifier to unreserve the reservation.

4 - /IDENTIFICATION_NUMBER=n

    Specifies which reservation is to be unreserved. This qualifier
    is required when you have multiple reservations of the same
    generation of an element. /IDENTIFICATION_NUMBER can be used
    instead of /GENERATION when you have multiple reservations. Use
    the SHOW RESERVATIONS command to determine the identification
    number of each reservation. The identification number appears
    before the user name.

5 - /LOG (D)

    Controls whether CMS displays success and informational messages
    on the default output device. By default, if the command executes
    successfully, CMS displays a success message. If you specify
    /NOLOG, success and informational messages are suppressed. Any
    warning, error, or fatal error messages are displayed regardless
    of whether /LOG or /NOLOG is specified.

6 - /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 (ELEMENT, GROUP, CLASS)
       ELEMENT (D)
       NOELEMENT
       GROUP (D)
       NOGROUP
       CLASS (D)
       NOCLASS
       NONE--equivalent to (NOELEMENT, NOGROUP, NOCLASS)

    You can specify either ALL or NONE, or any combination of the
    [NO]ELEMENT, [NO]GROUP, and [NO]CLASS keywords.

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