not a "hard" code. I mean, even in their freshman years CS students are
taught to use enums and constants instead of literals.

That is constants that are used more than once with the same meaning.
It is a deadly sin to use throw codes more than once, so this doesn't
apply.

Wrong. It's a way to abstract a numerical literal - so if things happen to change, you don't have to change them everywhere. It's also a way to self-document a program. Any idea what -22 THROW does (without consulting the standard)? Any idea what E.BADADR THROW does?

In the early days of microcomputing memory was severely limited and error codes
were used to save space.  But how much need today and what's wrong with ABORT"?
I don't use forth for scripting which might require sending codes and can't think
of an app where I've used codes.  Is the ANS list of error codes aimed at special
needs?  Because FWIW I'm not feeling any.
