This specification indicates that the calling program
supports extended attribute DSCBs. An extended address volume may
have these DSCBs allocated to it. The returned DSCBs (format-3, format-8)
may contain extent descriptors described by 28-bit cylinder addresses
or DSCBs (format-9) that contain additional attribute information. For fully qualified data set names in the Filter Criteria
List, a CVAFFILT request fails if the EADSCB=OK, indicator is not
set and the DSCB associated with the fully qualified data set name
is a format-8 DSCB.
For partially qualified data
set names in the Filter Criteria List, a CVAFFILT request fails if
the EADSCB=OK, indicator is not set and a DSCB associated with a data
set that matches the Filter Criteria List is a format-8 DSCB.
The
failing error code for these cases will be reflected as follows:
- Data set name status in the FCL (FCLDSNST) is set to a status
value of (X'06'). This status code indicates that a data
set name is described by a format-8 DSCB and the caller did not specify
support for an EAV with the EADSCB=OK keyword.
- Set the no resume CVAF status code (CVSTAT) of STAT072
- Return code 4.
EADSCB=OK will set the CV4EADOK indicator in the CVPL.
