point of developing IPS in the first place was that AMSAT couldn't
afford to buy a FORTH license at the time, and in any event they wanted
multiprocessing support that I believe they felt was missing from FORTH.
Since the original development of the language was by a German, the
language keywords are in German. There was an effort to "translate" the
language for English-speaking programmers, but my understanding is that
the translation never really caught on, and the key US contributors to
the satellites ended up writing German IPS.
Meinzer, btw, is an amusing fellow. AMSAT has been discussing a space
probe that would be sent to another planet in recent years, and at one
point someone asked Meinzer what would happen if the probe missed
orbital insertion there. His answer was something to the effect of
(imagine a German accent here) "then we would set a new amateur radio
distance record every day."
