Table 1-15 Text Units for Dsname Allocation Function

Text Unit Key	Mnemonic	Description	Supported
0x0001	DALDDNAM	ddname	YES
0x0002	DALDSNAM	Fully qualified data-set name	YES
0x0004	DALSTATS	Data Set status. Values are: __DISP_OLD, __DISP_NEW, __DISP_MOD, and __DISP_SHR	YES Note: When you code DALSTATS, LEN must be 1.
0x0005	DALNDISP	Specifies the normal disposition of a data set. Values are: __DISP_CATLG, __DISP_UNCATLG, __DISP_DELETE, and __DISP_KEEP	YES Note: When you code DALNDISP, LEN must be 1.
0x0006	DALCDISP	Specifies the conditional disposition of a data set. Values are: __DISP_CATLG, __DISP_UNCATLG, __DISP_DELETE, and __DISP_KEEP	YES Note: When you code DALCDISP, LEN must be 1.
0x0010	DALVLSER	Volume serial number of the device a data set will reside on	YES
0x003C	DALDSORG	Data Set organization of a data set. Values are: __DSORG_unknown Unknown __DSORG_VSAM VSAM __DSORG_GS Graphics __DSORG_PO Partitioned organization __DSORG_POU Partitioned organization unmovable __DSORG_DA Direct access __DSORG_DAU Direct access unmovable __DSORG_PS Physical sequential __DSORG_PSU Physical sequential unmovable.	YES (Support the value of __DSORG_PO and __DSORG_PS) Note: When you code DALDSORG, LEN must be 2.
0x0049	DALRECFM	Record format of a data set. The values are: _M_ Machine-code printer-control characters _A_ ASA printer-control characters _S_ Standard fixed, spanned variable _B_ Blocked _D_ Variable ASCII records _V_ Variable _F_ Fixed _U_ Undefined _FB_ Fixed blocked _VB_ Variable blocked _FBS_ Fixed blocked standard _VBS_ Variable blocked standard.	YES (Support the value of _FB_ and _VB_) Note: When you code DALRECFM, LEN must be 1.
0x0042	DALLRECL	Record length of a data set	YES Note: When you code DALLRECL, LEN must be 2.
0x800B	DALRECO	Specifies the record organization of a VSAM data set. Values are: __KS, __ES, __RR, __LS.	YES Note: When you code DALRECO, LEN must be 1.
0x800C	DALKEYO	Specifies the key offset. The position of the first byte of the key in records of the specified VSAM data set.	YES Note: When you code DALKEYO, LEN must be 4.
0x0040	DALKYLEN	Specifies the length in bytes of the keys used in the data set.	YES Note: When you code DALKYLEN, LEN must be 1.

Note:

• The combination of DALRECFM and DALRECO is not allowed because the DALRECFM keyword only applies to non-VSAM data sets, while the KS, ES, RR, and LS values of the DALRECO keyword only apply to VSAM data sets.
• The combination of DALDSORG and DALRECO is not allowed.
• It is not supported to allocate a variable-length VSAM data set.
