Difference between revisions of "IF a THEN b ELSE c"

Latest revision as of 00:13, 1 June 2016

This conditional expression returns «b» if «a» is true (1) or «c» if «a» is false (0), for example:

Variable X := 1M

Variable Y := 1

IF X > Y THEN X ELSE Y → 1M

returns the larger of X and Y.

It is possible to omit the ELSE clause:

IF X > Y THEN X

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.
