How do I move the accounting data from the input tape to the output tape?
This will require you to code an exit for COPYCAT called CTCOPYUX. We do supply a skeleton for this program in the CTAPSRC library. There is JCL in the CTAPJCL library, member CTCUXREC to use SMP to apply your changes. You will also need to use the USEREXIT parameter in your control statement to tell COPYCAT to use the exit.
