DLBL Options
Description DLBL option codes provide special BIM-EPIC processing that is
unavailable with standard VSE DLBL parameters. See “
DLBL
Statements ” for an overview of DLBL statements.
DLBL Option
Codes
The following option codes can be used with the DLBL statement.
Code Action Description
A Align allocation on
cylinder
boundaries
Aligns the disk allocation on cylinder
boundaries. Valid for CKD devices only.
Allocations for direct access (DA) and
ISAM datasets are aligned automatically.
B=n Reblock (n=1 to
32767|MAX|OPT)
Changes the block size of the datasets
without recompiling the programs. Valid for
datasets with either fixed or variable record
formats. Reblock with caution when
running programs that use physical IOCS.
These programs must be able to support
reblocking. Specify either MAX for
full-track blocking or OPT for half-track
blocking.
C Conditionally
catalog
Puts the version in the DSN Catalog in
conditional catalog status at close.
D Delete after closed
as input
Deletes the dataset after the dataset is closed
for input. The code is not required for
compiler work areas, BIM-EPIC Common
Work Datasets (CWDS), or SORTWK files.
These files are deleted automatically at
close.
E Concatenate
datasets
Invokes dataset concatenation, which
causes the problem program to read two or
more files as if they were a single file, using
just one open and one close. Dataset
concatenation can only be performed for
cataloged datasets. This code differs from
dataset drop, option code T, in that dataset
drop only processes one dataset when a
program issues a single open.
