NAME : HCPUZPAG DESCRIPTION: PREFIX STORAGE AREA - MACHINE USAGE DSECT : UZPAG FUNCTION : THIS CONTROL BLOCK DESCRIBES THE ARCHITECTED FIELDS IN PAGE ZERO (EITHER REAL ZERO OR ABSOLUTE ZERO DEPENDING ON USAGE). THIS IS USED TO REFER TO GUEST PAGE ZERO. FOR HOST PAGE ZERO, THE PFXBK COPY FILE IS USED INSTEAD OF UZPAG. LOCATED BY : VMDPAGZP (WHILE NOT IN CONSOLE FUNCTION MODE) - HOST REAL ADDRESS OF THE GUEST PAGE ZERO CREATED BY : NOT APPLICABLE (CREATE AS A FUNCTION OF THE GUEST OPERATING SYSTEM DELETED BY : NOT APPLICABLE RELOCATION CONSIDERATIONS : None Notes : This copy file can be used to map the architected fields of the guest Prefix Storage Area for z/Arch and page zero for System/370 and ESA/390 guests. For z/Arch guests the PSA is 8K, that is, two contiguous pages in guest storage (but not necessarily contiguous in host storage). UZPAG - Maps page zero for 370 guests. Maps page zero for ESA guests. Maps page zero (1st page) of the 2 page z/Arch Prefix Storage Area UOPAG - Maps page one (2nd page) of the 2 page z/Arch Prefix Storage Area |
