INZU596E A USING COPY CLAUSE IS MISSING IN AN UNLOAD BLOCK.


        Explanation
            There is an UNLOAD block without a USING COPY clause, but there is at least one
                UNLOAD block with a USING COPY clause in the control file. When you unload from a
                copy, all the UNLOAD blocks must be specified with a USING COPY clause. 
        
        User response
            Either specify all the UNLOAD blocks with a USING COPY clause, or specify none of them with such a clause.
