The COPY control statement is used to copy a database. The output database must be a newly created, empty database.
The COPY control statement can also be used to reorganize a database and reclaim blocks in the database that are allocated but not currently being utilized.
Note: To merge databases, use the RMOUTIL utility.
The high-level name of the output database must have been defined previously with the NAME control statement (or the PARM parameter of the EXEC JCL statement).
