The reserved word is
belongs to object-oriented programming.
The is
operator is used to test whether the object is an instance of the specified type (class or child class). It takes an object on the left side of the is
operator and
a type on the right side of the operator. The result is the value of boolean indicating whether the object belongs to this type or not.
Example:
...
If fruit is TCitrusFruit then ... // Check if the fruit object belongs to the class of TCitrusFruit
...
