Command_Parameters

old-class-expression

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

new-class-name

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

remark

   Specifies a character string for the creation remark of the new
   class 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 class is used for the creation
   remark of the new class, but a null remark ("") is logged in
   the history file.
