[comp.lang.smalltalk] Different types of subclasses in Objectworks for Smalltalk 2.5

mongoose@spf.trw.com (Julian Watkins) (04/19/91)

In looking around Parc Place Systems Objectworks for Smalltalk 2.5, I have
come across several classes which are specified to be special types of 
subclasses.  For example:

	ArrayedCollection variableSubclass: #Array
	IntegerArray variableByteSubclass: #ByteArray

In version 2.3 another subclass type existed called variableWordSubclass:, but
it seems to be gone in version 2.5.

Does anyone out there know what the difference is between subclass: and 
variableSubclass: ?  I have searched in the Parc Place documentation, the blue
book, and both volumes of Inside Smalltalk, but haven't found any references
to these.  Thanks for any info.
