InterSystems: The power behind what matters   

Specifies whether instance methods in this class can use the now-obsolete %this variable.
To enable instance methods in the class to use %this, use the following syntax:
Class MyApp.MyClass [ LegacyInstanceContext ]  { //class members }
Otherwise, omit this keyword or place the word Not immediately before the keyword.
If this keyword is true, instance methods in this class can use the %this variable, which is now obsolete (replaced by $this). If this keyword is false, instance methods cannot refer to %this.
Effect on Subclasses
This keyword is not inherited.
If you omit this keyword, instance methods cannot refer to %this.
