You can pretty much write the same in Squeak too:

1 to: 10 do: [:i |
    Transcript
        show: i; tab;
        show: i * i; tab;
        show: i * i * i; cr].

Actually, there's a squared method, but unfortunately, there's no cubed
method ;-(

Also, it might be nice if Transcript

Essentially the same in Pascal. But note that the "print" statement

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.

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).
