Well, your result is nothing like I ended up with; you found a much<br>more elegant solution (iterating over the exp for example). But note<br>that to create that code I'd have to know about the class String,<br>streams, collect: (a powerful but really new concept) and the
<br>raisedTo: method. Not hard stuff, of course, but, as you properly<br>say, it's a question of familiarity and only that.<br><br>In Basic, it's something like:<br><br>repeat with i = 1 to 10<br> print i; i*i, i*i*i<br>

Essentially the same in Pascal. But note that the "print" statement<br>just prints stuff in a predictable place. When I solved the problem<br>in Smalltalk, I ended up believing that I needed to use the<br>Transcript for output, which involved figuring out how to get one to
<br>open and print stuff.</blockquote><div><br>I see what you're trying to get at, but unfortunately, this is not a particular good example, because It's the same in other languages too. <br><br>I don't know Pascal/Basic, but if you were to do it in Java, or C#, you'll end up using the StringBuilder class, which is just the equivalent to the Stream here. In C#, StringBuilder is part of
System.Text, which requires a 'using' statement, so it's not a module that can be used out of the box either (and I'm sure the same is true in the Java case).<br><br>Duncan.</div></div>
