+Ternary operator can be used as a shortcut for the IF/ELSE statement.
+
+### Syntax
+
+	condition ? a : b
+
+_condition_ is a boolean expression.  
+_a_ and _b_ are expressions to evaluate. The operator returns _a_ when condition is TRUE and _b_ when condition is FALSE.
+
+### Example
+
+	PROCEDURE max(a, b: INTEGER): INTEGER;
+	VAR
+		result: INTEGER;
+	BEGIN
+		IF a > b THEN
+			result := a;
+		ELSE
+			result := b;
+		END;
+		RETURN result;
+	END;
+
+This code above may be rewritten in much shorter and cleaner manner using ternary operator:
+
+	PROCEDURE max(a, b: INTEGER): INTEGER;
+		RETURN a > b ? a : b;
+	END;
