Required Arguments
- BASIC
-
specifies that the
system selects the BASIC format if the data set is sequential (DSORG=PS
or PSU), or if DSORG is omitted from all sources and the data set
is not VSAM. The data set cannot exceed 65535 tracks per volume.
- LARGE
-
specifies that the
system selects the LARGE format if the data set is sequential (DSORG=PS
or PSU), or if DSORG is omitted from all sources and the data set
is not VSAM. The data set can exceed 65535 tracks per volume.
- EXTREQ
-
specifies that the
data set is in the EXTENDED format if the data set is VSAM, sequential,
or if DSORG is omitted from all sources. The assignment fails if the
system cannot allocate an extended format data set.
- EXTPREF
-
specifies that the
data set is in the EXTENDED format if the data set is VSAM, sequential,
or if DSORG is omitted from all sources. If extended format is not
possible, then the system selects the BASIC format.
- NONE

specifies that the
default DSNTYPE of the system should be used when a new sequential
file is allocated.
