Thanks Peter and Michael --- I feel bad if you had to do extra work just because someone demanded *me* the service because he knew "it would be more helpful for those seeking the info" or equivalently said someone didn't seek the info personally. Anyway, it proved that the date of prior postings was sufficient for those who are competent to retrieve necessary information. -- Ryuji Suzuki "Keep a good head and always carry a light camera." ============================================================================================================= To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there.
