Creating fixed classes
subclass:classInstanceVariableNames:instanceVariableNames:classVariableNames:poolDictionaries:, subclass:instanceVariableNames:classVariableNames:poolDictionaries:
These messages can only be sent to another fixed class.
Porting tip:
Smalltalk/V supports the second message, but not the first, while Objectworks\Smalltalk supports neither. Neither Smalltalk/V nor Objectworks\Smalltalk provide Class messages for creating classes with class instance variables, although it is possible to build such classes. Objectworks\Smalltalk uses different subclass creation messages that also specify the category.
