Hi,

This does answer the questions. However, what I really was trying to find out (what I should have asked), was how does this correspond to the grammar mentioned in the programmers guide. I'm thinking from a parsing point of view.

Is this a correct parse? doIt. expression. unary-message. receiver smallcap-keyword. [expression] smallcap-keyword. null smallcap-keyword.

In essence, most of the messages parse a null as the receiver.

I was reading the self grammar. Am I right in assuming that... doIt. or a: setSlot: 'x' With: doIt.

works, by having the receiver of the unary message doIt (which is probably a slot), is parsed as a null token for each of these expressions. Which would imply the default 'self' :-) as the receiver?

Just a quick check,

I am not sure if this is what you are asking, but typing

doIt

at the prompt (or in an evaluator in the graphical user interface) is indeed parsed as the unary message 'doIt' sent implicitly to 'self', which in the case of the prompt is the shell object and in the case of an evaluator it is the object represented by the outliner the evaluator is in. I'll indicate this by writing it as

<self> doIt

ok? The expression

setSlot: 'x' With: doIt.

would mean

<self> selfSlot: 'x' With: (<self> doIt).

Here the 'doIt' message is sent to 'self' (shell or object represented by outliner) and the result of this is used as an argument (along with the string object 'x') to the 'selfSlot:With:' message that is also sent to 'self'.

I think I just repeated what you had already written, but if that is what you were asking then I hope I've confirmed your impression.
