Assembler instructions (such as load, store, add, and move character) manipulate the data in a data space. When you use instructions to manipulate data in a data space, your program must use the set of general purpose registers (GPRs) plus another set of registers called access registers. Using access registers describes how to use access registers to manipulate data in data spaces.
