Poor terminology, perhaps.

But it IS software that is running, IN SPITE OF the intent of OS/400.  If
Rochester can't program a way to PREVENT it from running, then it is not all
that far off from a "virus".  That is, unless they are prevented by legal,
rather than technological reasons.

FASCINATING...!

But, RIGHT NOW, pragmatically speaking...?

Does it require hardware change to keep data/pgms (say, voting results and
algorithms) private, for all intents and purposes...
