Example: $_ . "\n" That would result in the concatenation of $_ with a string containing the new line character, "\n". $_, would be valid code, but it would probably serve no other purpose than the one of $_ by itself. Was that helpful? If not, give an example and we'll try to put some light on it :-) > Regards Best regards, jac -- José Alves de Castro <[EMAIL PROTECTED]> http://natura.di.uminho.pt/~jac -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
