[expr] logical "or" operator, dual of [&&]. Returns falsity if both arguments are boolean false, and truth otherwise. Note that this operator ''short-circuits'', and does not evaluate its second argument if the first is true. See [|] for bitwise "or". Note that this operator does not have a command equivalent in [tcl::mathop]; use the [if] command instead. ---- !!!!!! %| [Category Operator] |% !!!!!!
