Specifying Class Method
On the Characteristics screen we select Class Method.
(Caché, like many object systems, has two types of methods: instance and class. If you would like to understand why AddShow is a class method, click here. If you're happy to just take it on faith, read on.)
We then select cache as the programming language for the method.
Finally, we can press the Finish button and then start to edit the code for this method within the Class Editor window.
