It has to work otherwise you wouldn't be able to access structured results
in a C program either. At some point the contents of the stack have to be
copied to the variable that the function is assigned to. e.g.
c = Xyz();
The more I think about it the more I uderstand the reluctance to implement
structured results ;-)
How are you by the way? I was hoping I might be able to catch up with you at
another Oberon Day this year but time is running out ...
Cheers,
Chris
