The COPY GROUP command uses an existing library group to copy
    and create a new group in the same library or in another library.
    The original group is left unchanged. The group attributes are
    copied in full and an identical set of elements and groups are
    inserted into the new group. The elements to be inserted into
    the new group must already exist in the target library.

    CMS must be able to create one new group for each old group.
    When you use wildcards, or a comma list in the input group
    specification you must specify a wildcard ("*") as the output
    group specification.
