A class is "just" another object whose own class is Class. I actually don't know when the class initialisiation method is called after creation. As usual, if all it does is things you know to be safe, go ahead and call it manually.<br>

<div>Wow. I wasn't aware that there was both a class and instance initialize method. Thanks for explaining that!</div>

<div>What causes the class initialize method to be invoked ... and reinvoked after I change it?</div><span class="q"><br>

</blockquote><br></span>Thanks! This brings up another question. Where is a good place to initialize a constant? I see in the case of "Float pi" that it is held in a class variable that is initialized in the initialize method. Isn't it the case that the initialize method is only called if a Float object is created? Also, isn't it called every time a Float object is created? It seems that would mean if I followed that pattern for one of my own constants then I wouldn't be sure it was set and I'd pay the cost of setting it many times.<br>
