This is just a rough 'back of the envelope' figure not counting commas, etc, or the actuall bytes in 256K - I just used 256,000 as the number. :-) :-) :-) :-) :-) :-) :-) :-) :-) :-) :-) :-) :-) :-) :-) Bill -- Bill Vermillion - bv @ wjv . com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-fs" in the body of the message
