text_io and grid printing

[Mehdi Saada <00120260a@gmail.com>]

I wanted to use set_col and set_line to print things as in a grid, (to print a matrix) but it seems I was wrong ?
Set_Col (1); Put ("1"); Set_Col (2); Put ("2"); Set_Col (3); Put ("3");
Gives "123"
but Set_Col (2); Put ("2"); Set_Col (1); Put ("1"); Set_Col (3); Put ("3");
gives
 2
1 3

Is there something with linux' implementation ? How do you use to print things like a grid in a portable ? Are you forced to use some complicated curse-like library for that ?
