Ooops, I messed with the layout. Here again:

Hmm...

1 to: 9 do: [:i | 1 to: i do: [:j |

  Transcript showln: ('{1} * {2} = {3}' format: {i.j.i*j}) ]].

Best,

I am using Smalltalk to type in Transcript window a 1-9 multiplication table
.

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 ?
