This action checks whether a number is greater than zero.

__ Trigger [required]__

**<X>** (non-repetitive numeric trigger [required])**:**
The checked number.

__Exits__ [none required]

The two exits represent two mutually exclusive possibilities:

**<Yes>** (non-repetitive numeric exit [not required])**:** The
input number (the value of **<X>**) in case it is positive
(i.e. greater than zero).

**<No>** (non-repetitive numeric exit [not required])**:** The
input number (the value of **<X>**) in case it is not positive
(i.e. smaller than or equal to zero).

__Notice:__ If there is a need to distinguish between 3 different cases
(**<X>** greater than zero, **<X>** equal to zero, or
**<X>** smaller than zero),
use Compar.
