Description
The OB SET NULL command stores the null value in the language object designated by the object parameter.
In the property parameter, pass the label of the property where you want to store the null value. If the property already exists in object, its value is updated. If it does not exist, it is created.
Note that the property parameter is case sensitive.
Example
We want to put the null value in the "age" property for Lea:
var $ref : Object
OB SET($ref;"name";"Lea";"age";4)
// $ref = {"name":"Lea","age":4}
...
OB SET NULL($ref ;"age")
// $ref = {"name":"Lea","age":null}
