While reading, the content of data registers starting from Sa will beoverwritten by the content of file registers addressed by the base file register Sb and record pointer Pr; whilewriting, the content of file registers addressed by the base file register Sb and record pointer Pr will beoverwritten by the content of data registers starting from Sa; L is the operation quantity or record size. Theaccess of file register adopts the concept of RECORD data structure to implement. For example, Sa=R0,Sb=F0, L=10, the read/write details shown as belowSbSaR0 ~ R9(L=10)F0 ~ F9(L=10)F10 ~ F19(L=10)F20 ~ F29(L=10)F30 ~ F39(L=10)Pr = 0Pr = 1Pr = 2Pr = 37-124
