Hi everybody!

I was playing with arrays (for matrix calculation) when I've got this
strange error. When I set the value it seems ok, but when I check it
out... it's not there anymore!
Here's the bugged code:
----------------------------------------
 int X=2;
 int Y=2;
  for (int i=0; i<X ; i++){
    for (int j=0; j<Y ; j++){
      if (i==j) data[i,j]=1; // defines a 2x2 identity matrix
      else data[i,j]=0;
      cout << data [i,j] <<", "; // SEEMS OK...
    }
  }

  cout << endl;

  //  check it out
  for (int i=0; i<X ; i++){
    for (int j=0; j<Y ; j++){
      cout << data [i,j] <<", "; // WRONG!!! WHY ???
    }
  }
-----------------------------------------
Any clue?
I'm using djgpp + rhide. 
 
Thanks a lot!

Anderson.
