Thanks but it STILL doesn't work.  Here's what symify tells me:

Shutting down Allegro

And line 48 is indicated:

     pix_y = (random() % res_y);
     if (matrix[pix_x][pix_y] == 1)
        continue;
     else
          matrix[pix_x][pix_y] = 1;

     putpixel(screen, pix_x, pix_y, RGB(color_red, 0, 0));
     }
return 1;
}
