Description

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

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