Page 459 of the publication http://www.redbooks.ibm.com/redbooks/pdfs/sg247946.pdf on paragraph "21.1.2 Local system area" says:=== Quote ===Note: A keyword has been added to the IARV64 REQUEST=GETSTOR, LOCALSYSAREA=NO|YES, to indicate that the memory object is to be allocated from the system area of the 64-bit address space map. LOCALSYSAREA memory objects are allocated in the system area that starts atX’8_00000000’ - 32 GB and ends at X’28_00000000’ - 288 GB. Only authorized users may use this keyword.=== End of quote === ...however, 288G is x'48_00000000', not x'28_00000000’, or am I missing something? Another question: Are these boundary lines of the LocalSystemArea sort of "fixed by architecture", or need they (at least the high end) be looked up in some control block?
