[Oberon] a module a page (keeps the mind sane)?

[Jörg]

F.P.
"Coroutines" is very small;  if I remember correctly a page of code for the whole module or so.
This module is very compact but not easy to understand for outsiders as it "just" plays around with internal registers.
If I have time I might port it over.

Hi Jörg,

I saw the coroutine module is not yet written for project oberon.
But that does not keep me from trying out the concept of cooperatieve multitasking.
I will look into that,

Thanks.
