[Gambas-user] array of object is SO needed

[nando_f at nothingsimple.com]

I've done an array[][] of objects for Sudoku
In fact, I have 3 kinds of arrays pointing to the same single 9x9 array

9 sets of an array of 3x3 squares which point to the same 9x9
9 sets of an array of 9 for columns pointing to the same 9x9
9 sets of an array of 9 for rows pointing to the same 9x9.

It doesn't matter which way you look at it, it all points to the same 9x9
I get to address it as a nine 3x3, or nine rows or nine columns.

Each array element was a label where I could set the x,y for each.

This structure made it easier for how I did it.

There may be better, or even more efficient, but it was cool.
Gambas is pretty cool.
