I must have missed that when I read that section. Thanks. Before I tried [:upper:] I tried [A-Z] and it didn't seem to work either (I was doing '~s [A-Z]' and it still showed messages *not* containing any upper case letters). Perhaps 'bracketed' things somehow miss the check for upper case letters. It probably doesn't check everything for upper case letters as (presumably) something like ~C shouldn't get taken as one. I had a quick glance at the source, but state machines and re compilers are not really *that* fun. > > HTH, > Gary > > -- > Gary Johnson | Agilent Technologies > [EMAIL PROTECTED] | Spokane, Washington, USA > http://www.spocom.com/users/gjohnson/mutt/ | -- Benjamin Smith <[EMAIL PROTECTED], [EMAIL PROTECTED]>
