right there are conforming implementations and conforming applications solaris and ast/ksh printf are conforming implementations printf ----- is a non-conforming application non-conforming means non-portable the reality is most people code to eliminate diagnostics but that is not sufficient to "guarantee" conformance we can workaround the printf problem by issuing a warning diagnostic for invalid option (its currently an error with non-0 exit status) and treat the option and all subsequent operands as operands that way the standard output will be the same and/but the non-conforming application will be nudged with a warning diagnostic which could say something like "use -- before the first operand that starts with -" -- Glenn Fowler -- AT&T Research, Florham Park NJ --
