Subject: Re: UndefinedObject

UndefinedObject is the class of the global object known as 'nil'.

Scratch DoIts (like when you select some text in a workspace and choose 'do it') are compiled as a method on UndefinedObject called 'DoIt', run, and then removed immediately.

Hi,

When I debug somethings I see

UdefinedObject>>DoIt

So #DoIt should be in UndefinedObject but I can't see it when I browse it?

An other things intresting is where do nil being initialized? [I know he

best regards,
