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.

2    /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.

3    /NAME=group-name

    Specifies the new name for the group. You cannot change the
    name of a group that has been set to READ_ONLY. The new group
    name cannot be the same as an existing group or class name.
    Wildcards and comma lists are not allowed. If you specify the
    /NAME qualifier, you cannot use wildcards or a comma list in the
    group name parameter, nor can you use a wildcard for the /NAME
    qualifier.

4    /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 GROUP
       GROUP (D)
       NOGROUP
       NONE--equivalent to NOGROUP

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

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

5    /READ_ONLY

6    /NOREAD_ONLY

    Establishes or alters the read-only attribute of a group. To
    change the characteristics of a READ_ONLY group, you must set
    the class to NOREAD_ONLY. NOREAD_ONLY is the default attribute of
    a group when it is created with the CREATE GROUP command.

7    /REMARK="string"

    Specifies a new remark to be substituted for the creation remark
    that is associated with the group.
