The second message indicates that compilation has completed, and the hexadecimal address represents the starting offset of the machine code that will be executed each time the method is invoked.
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.
