SYSTEM.COPY copies n consecutive *words* from src to dst. A word as used in
the Project Oberon RISC5 processor is four bytes.
The code resulting from a call to SYSTEM.COPY is generated by the procedure
ORG.Copy. If you have a look at this you will see that the address of both
the src and destination are incremented by 4 after each load and store
