Specifying a Super Class

Next, we need to specify what type of class to create. Because our new data type will be based on the Caché %IntegerOpens in a new tab data type from the standard (%Library) package, we click on Extends generated description: little1.gif and then fill in the name of our super class generated description: little2.gif.

generated description: creatingdatatype3 20111

(Alternatively, we could have clicked on “Datatype” and specified the super class later, but I prefer this route.)
