	Note that relations can be cascaded, with the interpretation that each operator applies independently to its surrounding pair of expressions. Thus, the expression: Expression <= Expression <= Expression (e.g. 5 <= age <= 50) specifies a “between” relation, which is TRUE only if the value of the centre expression falls in the specified range.
