I have a program that just won't work!  It compiles fine, but when I run
it, it gets this error:

.
the program source is this:

#include <conio.h>
#include "allegro.h"



 int main(void)
	{
        BITMAP *screen;
        int done;
        int x = 1, y = 1;

        allegro_init();
        set_gfx_mode(GFX_VGA, 320, 200, 0, 0);

		  do
			{
                        clear(screen);
                        putpixel(screen, x, y, x);

			// move player
			if (kbhit())
			{

				switch(getch())
						{
                                        case '8': // up
					{
                                        y += 5;
					} break;

					case '2': // down
					{
                                        y -= 5;
					} break;

					case '6': // right
					{
                                        x -= 5;
					} break;

					case '4': // left
					{
                                        y += 5;
					} break;

					case 'q':
					{
						done=1;
					} break;
						} // end switch
			} // end if player hit q

                putpixel(screen, x, y, x);

		} 	while(!done);// end while


       return 0;
	}// end main
