And such systems may be in use for 20+ years. I think I've overheard stuff at work where they are talking about having to do side-by-side examination of the generated object code to validate a new release of the compiler -- without changing the language standard in use. -- Wulfraed Dennis Lee Bieber AF6VN wlfraed@ix.netcom.com HTTP://wlfraed.home.netcom.com/
