i don't understand why the 3rd argument is negative. given $str1 = 'xxxxyyyyxxxx'; substr($str1, 4, 4) returns 'yyyy'; so wouldn't substr($str1, 4, 4, 'zzzz') replace 'yyyy' with 'zzzz'? thanks again. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
