TYPEFLE=WORK DTF Datasets
Description Datasets that have TYPEFLE=WORK DTFs are processed differently
from other sequential datasets. Common TYPEFLE=WORK DTFs
include compiler work datasets and FORTRAN disk datasets.
BIM-EPIC can process TYPEFLE=WORK DTFs on disk only (DTFSD).
You can, of course, still use TYPEFLE=WORK DTFs with tape if the
tape dataset is uncontrolled.
TYPEFLE=WORK DTFs can be controlled as Start Track 1 or cataloged
datasets. However, you should use the DSN Catalog to eliminate many
allocation problems. For example, BIM-EPIC automatically reuses the
same extents used by an earlier version of a cataloged dataset, if one
exists. If you use Start Track 1 datasets, the old dataset is deleted the next
time a dataset with the same dataset name is opened.
Secondary extents are not allowed.
DSN Catalog In the DSN Catalog, you must:
Catalog the dataset as work. If you use Online Manager, specify
WRK. If you use TSIDMNT, specify WRK=YES.
Inhibit LUB allocation for the dataset by specifying a SYS
number in the definition.
JCL
Requirements
There are several JCL requirements you must consider.
Inhibit LUB allocation if this is not done through the DSN
Catalog.
For a DLBL, specify the DLBL option code N in the dataset
name.
For DD statements, include the OPTION=SYSnnn parameter.
