A new type of data cluster and an indirect addressing method are introduced. The improved database can be used more satisfactorily.
Listing 4 illustrates the base indirect addressing mode (line 64), so called because you start with a base address and add an offset to it to arrive at a final address.
Finally, in indexed register indirect addressing mode, both the base and the index are stored in registers.
Line 18 in Listing 2 illustrates the memory indirect addressing mode.
