Sorry this is a bit long.  I removed a few of the unimportant routines 
to shorten it some.

procedure update_screen()  
	
	blit(back_image, buffer, 1, 1, 1, 1, 1024, 768)           
	if someone_died = 1 then
	  blit(boom_image, buffer, 1, 1, loc_x, loc_y, 100, 100)
	else
	  masked_blit(ship_image, buffer, 1, 1, loc_x, loc_y, 87, 61)
	end if	
	if someone_died = 2 then
	  blit(boom_image, buffer, 1, 1, enemy_loc_x, enemy_loc_y, 100, 100)
	else
	  masked_blit(enemy_image, buffer, 1, 1, enemy_loc_x, enemy_loc_y, 87, 
24)
	end if
	blit(player_status, buffer, 1, 1, 50, 50, player_life, 20)
	blit(enemy_status, buffer, 1, 1, 750, 50, enemy_life, 20)
	blit(buffer, screen_ptr, 1, 1, 1, 1, 1024, 768)  
end procedure

	enemy_shoty = enemy_loc_y + 24
	update_screen()
	line(screen_ptr, enemy_shotx, enemy_shoty, (enemy_shotx - 300), 
enemy_shoty, makecol(200, 0, 0) )
	if loc_x >= (enemy_shotx - 300) and enemy_loc_x >= loc_x then  
		if loc_y <= enemy_shoty and (loc_y + 61) >= enemy_shoty then
			player_life -= 20
