DLBL Statements DLBL Options

Chapter 5. BIM-EPIC TLBL and DLBL Statements 5-11

Overrides BIM-EPIC's control of dataset. Valid ASSGN and EXTENT statements must be

included to process the dataset.

Inhibits LUB allocation for the dataset. Inhibiting LUB allocation is often necessary when

you are running programs that use physical IOCS. It is required with the BIM-EPIC

TSIDASS utility. See "LUB allocation" for more information.

Overrides configuration options ALLMALL=NO (default) and ALLMSG=NO for this dataset.

Allocation messages are issued for the dataset and for all other disk datasets opened after it.

For output datasets, EP039 is issued after the dataset has been opened, displaying the extents

allocated. EP052 is issued after the file has been closed, displaying the size of the extent after

truncation.

For input datasets, EP053 is issued to display the extent that has been opened, and EP051 is

issued to indicate that the dataset has been closed.

This option is ignored for system datasets (such as IJSYSLN) held open across job step

boundaries.

All unused space between the end-of-file record and the end of the last extent remains

allocated to the dataset. Use this option when additional records may be written to a file after

it is closed if the file is accessed later as a DA file. This option is required for any dataset

processed with a TYPEFLE=WORK DTF. This option is also required when you use the 'S'

option code (reuse same space).

Accepts the size specified in the EXTENT statement as the primary extent rather than the size

specified in the DSN Catalog. Pool name and secondary extent size are still taken from the

BIM-EPIC dataset definition. Use this option when the volume of data you are processing for

a dataset is significantly different from normal. This option is valid for cataloged datasets

only.

Deletes the dataset at end of job. Use this option for temporary datasets that are not closed as

input. This option is automatically activated for all SORTWK files. This option affects only

cataloged, non-generation datasets. Configuration option JOBACCT=YES is required.

Specifies the number of logical records the file is to contain. BIM-EPIC uses this number to

calculate the size of the extent required.
