Contact them and ask them about it. If they don't implement them, you
may also find they have equally viable alternatives. If they don't, and

And maybe you could end up discovering that hand waving doesn't cut it
and that there are very real world issues in customer code that come
to light big time when you try to run VMS code on Linux even with the
