Syntax

DLSEQDSNTYPE= BASIC | LARGE | EXTREQ | EXTPREF | NONE

BASIC: specifies a regular-format sequential data set that cannot exceed 64K tracks per volume.
LARGE: specifies a regular-format sequential data set that can exceed 64K tracks per volume.
EXTREQ: specifies that an extended-format sequential data set is required. The library assignment fails if the system cannot create an extended-format data set.
EXTPREF: specifies that an extended-format sequential data set is preferred. This library resides in an extended format data set if that format is available. Otherwise, a regular format data set is created.
NONE: causes SAS to not specify a DSNTYPE value when allocating the library data set. The type of data set created will be determined by the system, which uses default values that are supplied by the SMS data class, and so forth.

Details

Use DLSEQDSNTYPE to specify the default value of the DSNTYPE LIBNAME option, which can be specified on LIBNAME statements when creating new sequential-access bound libraries on disk.
