My knowledge of those documents comes from having actual paper copies 
while using actual physical machines, back in the day when these systems 
were new.

Pascal should have been easier. VAX Pascal (V2 and later) had all kinds of 
elaborate facilities (nonstandard, of course) for low-level interfacing to 
the system and to other languages, controlling storage layout in the 
linker etc. It was a full-on systems programming language and no mistake.

Again, I know all this from first-hand experience.
