Hi Michael

The 64KB limit is known, but I'm surprised as well that this limit is not
checked.

Add to ORG.CheckRegs the following IF:
   IF varsize + strx > 0FFFFH THEN ORS.Mark("too many globals") END;

Hennessy.Mod looks interesting as a benchmark to compare emulators.

I had to tweak it slightly so that it compiles in the original Project
Oberon compiler:

https://github.com/rochus-keller/OberonSystem/commit/1be6d381195d5bc32ff4aa4
d9e6b94dd5987165f


Unfortunately, the whole thing does not run, although it compiles fine.
I get some weird traps while trying to flush the output from the Writer to
the log buffer.


When removing a few tests and/or reducing their variable size so that the
module variables are below 64KB in size, it works.

Is that a known limitation of Project Oberon? It surprises me that the
compiler does not warn about it, but compiles it fine.


Regards,


Michael
