I would mention in such a presentation that the MF is the only architecture that
can reasonably pe programmed in ASSEMBLER language today, because the
instruction set is clear and straightforward and defined in such a way that it
is at the same time well performing on the machine and understandable to humans.

There is no other platform with existing applications in ASSEMBLER language
doing business critical work. And, if done correctly and supported by people who
have the needed skills to manage those applications, this is no problem at all.

I also see just in the last few days, that there is another culture of testing
and error recovery in the mainframe environment; we have component tests,
regression tests, diagnose tools, dumps etc., and we normally are able to
analyze the errors in a very early development stage and we find the source of
the error in the programs by ourselves and very fast. The software on the other
platforms is often tested only in a very late state, when the whole package is
built, and we then have to cope with strange program interruptions and we get
only minimal diagnose information which is not helpful - at least that's my
experience.

Kind regards

Bernd
