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.
