F.Y.I...

1.  I think you mean the System Workspace.

2.  We eliminated the System Workspace in Squeak 2.0, in favor of the 'do...' editable menu.

3.  You will find a lot of such handy expressions in SystemDictionary
	under the category 'housekeeping'.  You may also find
	printSpaceAnalysis (in 'shrinking') useful.
