Ooops, I messed with the layout. Here again:

1 to: 9 do: [:i | 1 to: i do: [:j | Transcript show: ('{1} * {2} = {3} ' format: {i.j.i*j}) ]. Transcript cr].

So, you can use #format: to format strings more concisely.

Here is my code:

*1 to: 9 do: [:i| 1 to: i do: [:j| Transcript show: j. Transcript show: ' * '. Transcript show: i. Transcript show: ' = '. Transcript show: j * i. Transcript show: ' '. ]. Transcript show: ' '; cr. ].* As can be seen, the above code, although working fine, looks far from beautiful and concise.

I had hoped to write something like :

*Transcript show: j '*' i '=' j * i.* Unfortunately, they are wrong. I remember C has a very nice way to handle that issue of mine.

Like, *printf("%d * %d = %d ", j, i, j * i);*

Is there a more elegant way to make Smalltalk codes elegant in this situation ?
