Defining Your Datasets With TLBL, DLBL, and DD Statements
For every controlled dataset that it processes, BIM-EPIC uses the information in the DSN
Catalog entry to update the VSE label area when the dataset is opened. Because this
information is recorded automatically, JCL can be very concise. Using the DSN Catalog
instead of JCL can be:
• simpler
• less error–prone
• easier to change
In many circumstances, all you need to specify for an input dataset is the DTF name (or the
ddname that the program uses) and the dataset name.
// TLBL TAPEOUT,'SYSTEM.BACKUP'
* //TAPEOUT DD DSN=SYSTEM.BACKUP
On DD statements for output datasets, you may also need to specify a device type.
* //DISKOUT DD DSN=SYSTEM.BACKUP,UNIT=DISK
