By default, methods are public and can be accessed anywhere. The names of each generated method is the property name concatenated with the name of the method from the inherited class. READ commands block until one of the following occurs: Namespaces are discussed later in this book. There is no further restriction on the order of these commands to the same port.

In classes provided by InterSystems, all parameters are defined in all capitals, by convention, but your code is not required to do this.
