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.
Best,
Marcel

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 ?

Down below's hell.
