As NicC says, this forum is for TSO type questions, and in most shops you cannot use tape from TSO.
In any event, the DD statements define whether the input or output datasets are on disk or tape; any control statement just will say, in essence, to copy from a DD statement that defines a dataset on disk to a dataset on tape. The control statement, or statements, if any are required, do not require any device information.
