Description

TWordField is the class created when a dataset must manage 16-bit unsigned integer data, of datatype ftWord. It exposes no new properties, but simply overrides some methods to manage 16-bit unsigned integer data.

It should never be necessary to create an instance of TWordField manually, a field of this class will be instantiated automatically for each word field when a dataset is opened.
