Sorry, I only have a Basic, Pascal & Fortran background. Difficult
to tell how to write C (or Cobol or...) in these conditions.
You lend me (or us three) such criminal intentions ?!

What indicates you that Mr Grant doesn't know enumarated types
and nice records and doesn't want to use them ? If he thought to
try it in Ada, it was surely to make use of Ada's "+"es...

It just seems to me that he has encountered the simple problem
of performing the "AND" instruction that surely exists among the
MIPS assembly instructions. That's all! How can you do easily
without modular types ? Arrays of boolean is an alternative,
perhaps cleaner. Anyway I guess that the goal of his project is
not getting compile time errors!

You dismiss the people who write elegant, portable C - maybe the
huge amount of 0.05 % of the C sources that are on the Web!
