Appreciated, Andrew, that worked. Now it's found something new to go wrong;
as the tutorial explains it, this should display a sprite and allow the user
to move it around the screen. New to this that I am, I still can't see how
this doesn't work (the blitting at the very least); the program simply
displays nothing but clear the screen and end with the pressing of the Esc.
key. Small program it is, I've included it below. It compiles fine, it just
refuses to display anything. Thanx in advance for help.

#include <stdlib.h>
#include <stdio.h>

#include "allegro.h"

BITMAP *pic;
PALETTE pal;

int x,y;

main(void)
 {
 //////The initpart
 allegro_init();
 install_keyboard();
 set_color_depth(16);
 set_gfx_mode(GFX_AUTODETECT,640,480,0,0);
 pic = load_bitmap ("test.bmp", pal);

 do

  {
  clear(screen);
  blit(pic, screen,0,0,0,0,32,32); //

  int key = readkey();
  //////// Now handle the control
  if(key[KEY_LEFT])
   x--;
  if(key[KEY_RIGHT])
   x++;
  if(key[KEY_UP])
   y--;
  if(key[KEY_DOWN])
   y++;
  } while(!key[KEY_ESC]);

set_gfx_mode(GFX_TEXT,0,0,0,0);
 destroy_bitmap(pic);
 }
