As far as I remember there was LDIR for mem copy (:

No, Ulm's Oberon compiler exists for Solaris/SPARC too.
Anyway the system calls are done via SYSTEM.UNIXCALL routine.
The first thing to do was to convert separate implementation and definition modules into revised Oberon modules with export marks.
Then I've prerared Unix bindings with H2O.
And the most difficult part is to compile the library with oo2c because oo2c behave in more strict, and I would say, true way.
There were some other issues too discussed in the ooc mailing list.

I am not a native speaker however my Russian is not bad.
As I learnt it mostly by reading literature, people from Russia say I talk like actors on radio. (:
I just need to install something which opens rtf files, like LibreOffice. Just I always compile software I use, and it takes more than 6 hours to compile office, which I barely ever use. May be Abiword can open rtfs.

Yes, may be our theme is not very appropriate (on topic) here.

Sincerely
