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