SmallTalk Tutorial

I'm on to page two of the Smalltalk tutorial (http://www.bitwisemag.com/copy/programming/smalltalk/smalltalk2.html). It focuses on the the syntax of SmallTalk programming which is fairly basic. It seems to build on a few basic commands. I've just gotten into creating arrays in the language which is fairly simple. One of the more interesting aspects of the code blocks it has me dealing with is the inclusion of primarily temporary variables which are defined only until the code is finished executing and then are destroyed.
