Defining Datasets with TBL, DBL and DD Statements

Description 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,

the JCL can be very concise. Using the DSN Catalog instead of JCL can

be simpler, less error-prone, and easier to change.

In most circumstances, all you need to specify for an input dataset is the

DTF name or the ddname and the dataset name that are used by the

program.

Examples The following are examples of defining your datasets with TBL, DBL,

and DD statements.

// DLBL DISKOUT,’WEEKLY.PAYROLL’

// TLBL TAPEOUT,'SYSTEM.BACKUP'

* //TAPEOUT DD DSN=SYSTEM.BACKUP

When defining DD statements for output datasets, you may also need to

specify a device type.

* //DISKOUT DD DSN’
