Oberon is (and always was) designed to enable you to directly access bytes
in absolute-addressed memory using its SYSTEM features:

  SYSTEM.GET(a, v) is equivalent to v := Mem[a]

and 

  SYSTEM.PUT(a, x) is equivalent to Mem[a] := x

where v and x are any basic type and a is an absolute address which can be
obtained e.g.

  a := SYSTEM.ADR(v)

where v is any type.
