Though you could try it, I did not, I don't think you can printf STDIN since it is an inbound IO pipe as opposed to outbound. This is a good demonstation of the all important comma operator. Notice the difference in the docs: printf FILEHANDLE FORMAT, LIST printf FORMAT, LIST In the first there is NO comma following the filehandle, this means it is interpreted in a different manner than the rest of the argument list, or probably to be more precise isn't an argument at all... I am sure one of the gurus will chime in with the actual technical name of what this spot is actually called in this context since I either don't know or it escapes me currently. http://danconia.org -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
