Gunther I didn't know JWasm had been for many other OS's - actually I sort of knew but forgot - so perhaps it shouldn't be a big problem. Still it doesn't happen by itself. If the HJ version for (e.g.) OS/2 were already ready just testing it would be a job ...
jj2007 you're prob right ... but may depend on what counts as a "level", for instance "EXITM" constitutes another level all by itself in some cases at least. And I love that phrase "it would be nice if somebody ["else" is implied :)] could ...". That is precisely the problem, who wants to do the work? (Who will bell the cat, to use an ancient proverb some may remember). That's why whatever does get done, is a one-person job
