Hello Listers , Apologies in advance if this is a dumb question . But every time i read the below paragraph from ABC volumes , i get lost in the middle .
*prefixed storage area* This area is often referred to as low core. The PSA is a common area of virtual storage from address zero through 8191 in every address space. There is one unique PSA for every processor installed in a system. The PSA maps architecturally fixed hardware and software storage locations for the processor. Because there is a unique PSA for each processor, from the view of a program running on z/OS, the contents of the PSA can change any time the program is dispatched on a different processor. This feature is unique to the PSA area, and is accomplished through a unique DAT manipulation technique called prefixing. In what way do they say PSA is a common area of every address space when there is a unique PSA for every processor ? Is there a different place where this concept is documented with more details ? .. Can someone help me understand the above statement ?
