TYPEFLE=WORK DTFs
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,
we strongly recommend that you use the 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.
1. Catalog the dataset as work ("WRK" using Online Manager, or WRK=YES using
TSIDMNT).
2. You can inhibit LUB allocation for the dataset by specifying a SYS number in the Catalog.
Inhibit LUB allocation if this is not done through the Catalog. For DLBLs, specify the DLBL
option "N" in the dataset name. For DD statements, include the OPTION=SYSnnn parameter.
