Just to add another remark on this topic. The official Oberon-07 compiler is in fact inconsistent:

- in ORG.FixLink:       L1 := code[L] MOD 40000H;  (*18 bits*)
- in ORG.FixLinkWidth:  L1 := code[L0] MOD C24;  (*24 bits*)

Does anyone know why?

PS: I would prefer to use C24 throughout. That way the compiler also automatically 
works ob boards with larger memories.
