See `-validate => 'key', -ValidateCommand => sub { length( $_[0] ) <= 10 ? 1 : 0 }` and the validation section of the Entry widget POD. With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday' Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error. "Science is about questioning the status quo. Questioning authority". In the absence of evidence, opinion is indistinguishable from prejudice.	[reply] [d/l]
