This conditional expression returns «b» if «a» is true (1) or «c» if «a» is false (0), for example:
:<code>Variable X := 1M</code>
:<code>Variable Y := 1</code>
:<code>IF X > Y THEN X ELSE Y &rarr; 1M</code>

returns the larger of <code>X</code> and <code>Y</code>.

It is possible to omit the '''ELSE''' clause:
:<code>IF X > Y THEN X</code>

If the condition is false, it gives a warning. If you ignore the warning, it returns [[Null]].

Conditional expressions get more interesting when they work on arrays. See [[IF a THEN b ELSE c with arrays]].
