}

int main(int argc, char **argv)
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DEPTH | GLUT_DOUBLE | GLUT_RGBA);
    glutInitWindowPosition(100,100);
    glutInitWindowSize(500,500);
    glutCreateWindow("List Example");
   
    glutDisplayFunc(display);
    glutReshapeFunc(reshape);

    glutMainLoop();
    return(0);
}

Then the result... alamak ayam sy terbalik....
