I don't know what the correct answer to this is. However, if the SANE spec seems ambiguous to you then it may seem likewise to a front end writer who might interpret it either way. Therefore for maximum resilience you might be better to bite the bullet and be prepared for either case. cheers, Jon -- ====================== Jon Chambers ===================== http://www.jon.demon.co.uk, 020 8575 7097, 07931 961669 =========================================================
