Yes, I like those. I originally had a retval variable rather than a retval()
function, but I changed as a function is read-only where a variable is
read-write. But that's probably excessive paranoia.

Probably. I worried about programs like diff() which return a non-zero exit code
to signal differences, even though differences specifically *aren't* errors...

But you have some good points.

Paul.
