old-group-expression

    Specifies one or more existing groups to be copied. If you
    specify more than one group to be copied, you must use a
    wildcard character for the new group name. An old group
    expression can be a group name, a wildcard expression, or a
    list of these separated by commas.

 new-group-name

    Specifies the name for the new group. The name cannot be the
    same as any existing group name in the target library. Wildcards
    are allowed. If you specify more than one group with COPY GROUP,
    you must use a wildcard character for the new group name.

 remark

    Specifies a character string for the creation remark of the new
    group to be logged in the history file with this command. The
    remark is enclosed in quotation marks. If no remark was entered,
    then the remark from the old group is used for the creation
    remark of the new group, but a null remark ("") is logged in
    the history file.
