Thanks for very interesting info.
Hope someone else will add more to this.
ISS is international station so as much info as possible should be
publicly available.
What you described is also very good argument in favor of Ada.
I left Russian Space Industry about 8 years ago so I do not really know
if Ada is used there now but at my time there most of software for onboard
machines and controllers was written in assembler. Some software was
written
mostly in Modula-2. Probably some in C but I am not sure.
Regards,
Vladimir
