Answer» Temporary datasets are datasets (FILE holding one or more records) that are only needed for the DURATION of the job and are deleted when the job is completed. They need storage only for the job duration and once the job is completed, they are deleted. These datasets typically are represented as DSN=&&name or simply without specifying a DSN. By using them, we can FORWARD the output of one step to another step in the same job.
