That said from memory I think it was Digitalk or Enfin that used to automatically generate accessors and mutators Sent from my Commodore 64

If you could only access instance variables in the class that defined them and therefore only in a subclass via an accessor / mutator method w that be a big problem in your view?
Yes.
I don't want to have to define accessors, which are public, just to have the subclasses access the instance variables.

In Pharo, open a browser on OrderedCollection, then click "Variables" in the top left of the window and then "array"... if you scroll through you can see that mostly OrderedCollection methods use it, but some SortedCollection (a subclass) methods also use it.
The model is similar to protected in Java (see http://docs.oracle.com/javase/tutorial/java/javaOO/accesscontrol.html ) except there is no "Package" column.

Similarly for class methods to access class-side variables, and for class and instance methods to access class variables.

I'm wondering about instance variables for support in Redline Smalltalk and want to get my understanding straight.
Are instance variables only accessible (without using #instVarNamed:) inside the method with the same name as the instance variable?
eg:
myInstVar ^ myInstVar.
Or can you reference an instance variable from a method that doesn't have the same name ?
anotherMethod ^ myInstVar.
Can someone give me or point me to an example of accessing an instance variable in Pharo Smalltalk?
