[Oberon] Volatile variables in Oberon

[Treutwein Bernhard]

Hi Wojciech,

> a high level Oberon array carries the hidden memory tag.

Yes, but as far as I know all recent implementation have the hidden
type tags at negative address offsets. You must know these 
implementation details and you are absolutely correct that these are 
dirty tricks. Therefore the IMPORT SYSTEM is essential, but I think these
tricks are essential for hardware programming.
