Dan, If I understand your question correctly, the first element of the array is always 0 and the last is always -1, so why can't you just call them like this $firstelement = $array[0]; # "peek" at the first element $lastelement = $array[-1]; # "peek" at the last element Hope this helps, Kevin -- Kevin Old <[EMAIL PROTECTED]> -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
