I don't see any forum section for such topics so I'll drop it here...

Interesting stuff to go back and read with things currently happening:

This sort of reminds me of my favorite threads (on exceptions) back in
2001.  The main point is that there are critical industrial uses of
Delphi where things are *much* different than the normal Windows
database app.  Here are two messages that are related:

Both the Rosetta spacecraft and the lander module Philae contain
several computers.

The main system is FORTH-based, which is also reflected by the
hardware that uses a stack-based FORTH–oriented processor (see https:/
/www.researchgate.net/publication/234265387_Embedded_Computer_System_o
n_the_Rosetta_Spacecraft for details). Other subsystems have been
developed with Ada, a language from the Pascal family that is
especially suited for mission-critical aerospace applications and that
is an established basis for real-time operating systems in space
flight.

And, as we learned now, the ground test equipment software has been
written in Delphi.

Altogether, Pascal seems to do a good job here...
