IF a THEN b ELSE c

Analytica User Guide > Using Expressions > IF a THEN b ELSE c

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.
