Yes, I realise, is a nature of FPGA Oberon. As TYPES are referred
as pointers, in absolute address space are bound to be unique, so type
tests are just comparing two INTEGERS.
This makes compiler simpler. Relative addresses + jump tables (if
needed), would require named types, this would complicate
the compiler. The loader, on the other hand, and memory management would
be simpler. Any code could run from any even address with possibly no
