I am a novice NeWS programmer and am having trouble understanding the programming concepts I see used in Sun's liteitem.ps. My question concerns the use of `self send' in a method of a subclass. Sometimes this construct is used and sometimes the method is just executed directly. What are the differences? Specifically, I cannot see the difference between: /method0 { ... } def /method1 { /method0 self send } def or /method0 { ... } def /method1 { method0 } def What happens different when a /method1 subclass send is executed? Don't they both start looking for method0 with the dictstack in the same state? I can't cause any differences in the test cases I have generated. What am I missing? Thanks...
