Yes I was going to comment on this too:
Informix:    raise exception -273,0,'You are not user administrator.';  --or
        raise exception -100;
Oracle:        raise program_error; -- where program_error is one of many Orcl predefined error numbers

I think we will need error numbers in the future that map directly to some text.
This would also help Michael with the ESQL/C preprocessor.
