Dumb question: What IS a trigraph?

[Luiz H. deFigueiredo]

A trigraph is a 'escape sequence' to allow C sources to be written in
machines that do not have special characters like #{}.

The format of a trigraph is:

??=	meaning #
??(	meaning {
??)	meaning }

There are others but I don't remember them now. I'd have to check.
Anyway, it is not the kind of beast you'd be likely to meet...

(sorry to post but problems with mailer.)
