Yes I do have them but without the ">>" signs

yes you should not see >> in the source code.

>> is used by convention in books to express that a method belongs to a class.

Example, if I write:

aMethod

� ^1

you do not know which methods is it.

But using:

MyClass>>aMethod

� ^1

you know that is the one of MyClass

�

This is what I have inside the CharacterToken Class

characterData: anObject

�� characterData := anObject

�

This is where pharo complains

characterToken :=� CharacterToken new.

characterToken characterData: AMPERSAND.

It says it doesn�t understand characterData though it is defined in the CharacterToken class

ok I did not get where is your problem.

can you send a small piece of your code?

The setters and getters were generated by pharo. So im not sure about what the >> is for

Hi,

Hello again,

If I have an instance variable A in ClassA and I want to use it in ClassB.

If I do the following �in ClassB

objectA := ClassA new.

�

objectA �A: "new value for A".

Why doesn�t this work? Isnt this calling the setter of A on the objectA ?� Pharo doesn�t understand it for some reason .

�

yes.

but a setter is regular method.

did you defined the method in ClassA.

also, by convention method names start with a lowercase.

Example:

�

Object subclass: #ClassA

� iv: 'a'

�

ClassA>>a: newValue

� �a := newValue

�

objA := ClassA new.

objA a: 1

�

Cheers,

�
