WDATA Prolog
Name : HCPWDATA
Description: vSIE common DAta area mapping
DSECT : WDATA
Function : This copy file contains a DSECT used to map (and
define) the vSIE common data area.
Located by : HCPVSDWS is the external symbol which identifies the
beginning of the data area which is mapped
by this DSECT.
Created by : HCPWLBBN during system initialization.
Deleted by : Not deleted.
Notes : When this DSECT is COPYed into the HCPWDA module, it
generates actual code instead of a DSECT. This permits
the definitions of these fields to be centralized here.

This access-list- designation-source origin indicates an access-list-designation source (it can be considered to be a PASTE or a DUCT) which contains the null ALD. 0004 4 Signed 4 WDANASTE Null ASTEO. This ASN-second-table- entry origin indicates an ASTE which contains the null STD, the null ATO, and the null ATL. 0008 8 Signed 4 WDANALD Null ALD. This access-list designation indicates an small access list containing all invalid access-list entries. 000C 12 Signed 4 WDANSTDC Null STD for control registers. This segment-table designation indicates a small segment table containing all invalid entries. 0010 16 Signed 4 WDANSTDA Null STD for ASTEs. This segment- table designation indicates a small segment table containing all invalid entries. This STD is not equal to the STD in WDANSTDC, but the STO is equal to the STO in WDANSTDC (the STL is different). 0014 20 Signed 4 WDANATO Null ATO. This authority-table origin indicates a small authority table, and every entry has a zero secondary-authority bit. The ATO in this field is aligned as it would be in the word that contains the ATO in an ASTE. 0018 24 Signed 2 WDANATL Null ATL. This authority-table length is the length of the authority table indicated by WDANATO. The ATL in this field is aligned as it would be in the halfword that contains the ATL in an ASTE. 001A 26 Signed 2 * Reserved for IBM use 001C 28 Signed 4 * Reserved for IBM use
