DO you want to just print vertical and horizontal lines?
use this function to print them:
it's for allegro
/* x_space and y_space is the space between the lines */
void print_grid(int x_space, int y_space, int grid_color)
{
   int i, x_max, y_max;
   x_max = SCREEN_W / x_space; //number of vertical lines
   y_max = SCREEN_H / y_space; //number of horizontal lines

   //print vertical lines
   for (i=0; i<x_max; i++) 
      vline(screen, i*x_space, 0, SCREEN_H, grid_color);
   for (i=0; i<y_max; i++)
      hline(screen, 0, i*y_space, SCREEN_W, grid_color);
}

This little function will print the grid on the entire screen.
I did not test this so, I'm not really sure it it works..
