Contains shared segment nuabers; up to four
segment numbers per word Pointers to each of the shared {age tables.
There is ene word for each shared segment. The entry is the same as S*1 SEGPAGE in "5!GTAftE: Segment Table." In attached processor (AP) mode, there will be two sets of page tables (FAGTAEt!) for each shared segllent; one for the main processor, one for the attached processor. SBRPAGE will point to the page tables for the lIain processor. The page tables fer the
attached processor will be at a fixed displacement (P1GE!P) froll those of the main processor. Section 1. CP Data Areas and Ccntrol flocks 99
