Line 50:
It should be noted that on the 6502 processor hardware is normally memory mapped, so this is often used for manipulating hardware.

First, an integer object will be created at address $100000:
<lang 68000devpac>MOVE.L #$12345678,$100000</lang>
Finding the address of a given object isn't actually possible in the same way it would be on [[C]], since anything loaded from an address is just a numeric copy and is not actually related in any way to the "object." The closest way is to label a memory address and load that label as a numeric constant.
<lang 68000devpac>myVariable equ $100000
MOVE.L #myVariable,D0
JSR printLong ;some unimplemented printing routine.</lang>
Creating a new object at that location is as simple as storing a new value there.
<lang 68000devpac>MOVE.L #$FFFFFFFF,myVariable</lang>
