WDATA Prolog
Name : HCPWDATA Description: VSIM common DAta area mapping DSECT : WDATA Function : This copy file contains a DSECT used to map (and define) the VSIM 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.

Hex Dec Type/Val Lng Label (dup) Comments ---- ---- --------- ---- -------------- -------- 0000 0 Structure WDATA VSIM common DAta area mapping Define HCPWDATA control block. 0000 0 Signed 4 WDANADSO Null ALDSO. 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 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. 0010 16 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. 0012 18 Signed 2 * Reserved for IBM use 0014 20 Signed 4 * Reserved for IBM use 0018 24 Signed 8 WDANASCC Null ASCE for control registers. This segment-table designation indicates a small segment table containing all invalid entries. 0020 32 Signed 8 WDANASCA Null ASCE for ASTEs. This segment- table designation indicates a small segment table containing all invalid entries. This ASCE is not equal to the ASCE in WDANASCC, but the STO is equal to the STO in WDANASCC (the STL is different). STFLE response pointers These pointers will contain host logical and host real addresses for each of three instances of guest STFLE responses. The order of these arrays match the order of index values assigned to VMDSTFNX which is used to index these arrays. 0028 40 Signed 4 WDANFLL (0) Array of host logical addresses of guest STFLE responses 0028 40 Signed 4 WDANFL3L Host logical address of STFLE response for 390 guest (non-XC) 002C 44 Signed 4 WDANFLZL Host logical address of STFLE response for z/Arch guest (non-XC) 0030 48 Signed 4 WDANFLXL Host logical address of STFLE response for XC guest 0034 52 Signed 4 WDANFLR (0) Array of host real addresses of guest STFLE responses 0034 52 Signed 4 WDANFL3R Host real address of STFLE response for 390 guest (non-XC) 0038 56 Signed 4 WDANFLZR Host real address of STFLE response for z/Arch guest (non-XC) 003C 60 Signed 4 WDANFLXR Host real address of STFLE response for XC guest 0040 64 Signed 2 WDANFLS Size of storage obtained for 3 copies of guest STFLE responses in DWs 0042 66 Signed 2 * Reserved for IBM use 0044 68 Signed 4 * Reserved for IBM use
