Algol 68 POSIX and errno procedure request for advice

[chris hermansen]

Good day everyone,

I am coding up more of the transput now that I seem to have found a way to
ease myself into it and as I mentioned previously I intend to base it on
the POSIX interface to the extent possible.

To this end, I see we have procedures errno, which yields the numeric POSIX
error number, and strerror, which "yields a string containing an
explanatory short description of the error".

>From my long-ago days of writing a bit of C, I recall preferring the
symbolic error code such as EACCES.

What approach should I use in GNU Algol 68 since constants such as EACCES
are not defined?
