("%@ is a var arg substitution for an object value—often a string, number, or date.") - The predicate in the documentation does not chain binary comparisons. The documentation doesn't show any operator precedence — even if legal, your proposal might be read as [[%f < value] < %f]. It _does_ show a "BETWEEN" operator. — F _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
