It's COMPASS all right, but a quick scan through it shows that it's more 
likely a run-time package, rather than a compiler.  Most interesting is 
the brief PP profiling program at the end.

FWIW, at about the same time this was being written, SYMPL was being 
floated to the SCOPE 3.4 people.  I recall some discussion about SYMPL 
including some elements of the then-nascent Pascal.  To the best of my 
knowledge, it didn't happen.

One wonders if Wirth ever considered coding the compiler in SYMPL...
