DLSEQDSNTYPE System Option: z/OS

Specifies the default value of the DSNTYPE LIBNAME option for sequential-access bound libraries on disk.
Valid in: Configuration file, SAS invocation, Options statement, SAS System Options Window
Category: File Control: SASFILES
PROC OPTIONS GROUP= SASFILES
Default: NONE
z/OS specifics: All

Syntax

DLSEQDSNTYPE=BASIC | LARGE | EXTREQ | EXTPREF | NONE

Required Arguments

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 are determined by the system, which uses default values that are supplied by the SMS data class, and so on.

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.
