I've got his Operating System Principles and The Architecture of
Concurrent Programs. I've seen his Programming a Personal Computer -
about the Edison dialect of Pascal as a systems programming language,
an offshoot of Concurrent Pascal, iirc.
I'm slightly amused by his statement published in the Wikipedia
article on him, :
"There, his first significant project was writing a parser for a COBOL
compiler for the Siemens 3003 computer. Subsequently, he wrote a file
system to be used during execution of the compiled COBOL programs,
later observing "I now understand that it was really a small operating
system, I had programmed. However, in the mid 1960s, the dividing line
between language implementation and operating systems was still not
clearly understood."[ "
Which is quite an understatement - it is probably one of the reasons
why Prof Lions considered Solo unsuitable as a general purpose OS for
students to work with and work on. It would not be impossible to
develop a non-Pascal-based OS on the Concurrent Pascal microkernel,
but I don't get the impression that he had planned for it.
http://pascal.hansotten.com/per-brinch-hansen/ is a good site about him.
