Data set specifications for non-VSAM data set
A non-VSAM data set has several attributes that describe the data set. When you want to
define (create) a new data set, you have to specify those values to tell the system which kind
of data set you want to allocate.
See also z/OS MVS JCL Reference, SA22-7597 for information about the data set
specifications discussed in this section.
Data set organization (DSORG)
DSORG specifies the organization of the data set as physical sequential (PS), partitioned
(PO) for PDS or partitioned PDSE, or direct (DA).
Data set name type (DSNTYPE)
Use the DSNTYPE parameter to specify:
► For a partitioned organized (PO) data set, whether it is a:
– PDS for a partitioned data set
– LIBRARY for a partitioned data set extended (PDSE)
► Hierarchical file system if the DSNTYPE is HFS
► Large data sets (see 2.16, “Volume table of contents (VTOC)” on page 45 for more details
about large data sets)
