Conditional Expressions Conditional expressions identify conditions to be tested to select one of alternate paths of control. This selection is determined by the truth value of a condition. Conditional expressions are used in the IF, SEARCH, EVALUATE, and PERFORM statements. There are two categories of conditions associated with conditional expressions: * Simple conditions. * Complex conditions. You can enclose either category within any number of paired parentheses without changing its category. This section describes both simple conditions and complex conditions.
