[Newbies] Where to 'declare' symbols

[John Almberg]

Hi Matthew,

Oh, duh! A method that simply returns a value *is* a simple solution.  
Thanks.

I just tried the class variable approach, too, (just to see how it  
works). It took me a while to figure out what you meant by  
initializing the Class but finally realized the only way to access  
the class variable was to do something like

MyClass initialize.
MyClass MySpecialConstant.

I guess inside a class method, you could access it like:

testValue > MySpecialConstant

Okay, I think I get it.

Thanks!
