The CDC Pascal compiler was written by Urs Ammann. I have probably got
the number of m's or n's wrong. There was an earlier version of Pascal
which was ported to the ICL 1900 by a group in England whose names I
ought to be able to remember but cannot.
I am not sure at this point where that compiler came from - whether it
was a port or an ab initio effort. I think it was written up in
Software Practice and Experience, somewhere in the mid seventies.
Turbo Pascal did generate machine code, but a lot of it was calls to
an approximately 12K kernel which was presumably entirely hand coded
in assembler, so it was somewhere between a compiler and an
interpreter. When you output a com file, this kernel would be output
as the start of the file.
