#include <stdio.h>
#include <stdlib.h>
#define  T 2000
int n=0,px,py;
main()
{
    int gd=DETECT,gm,i,j;
    clrscr();
    gotoxy(25,4);
    printf("DON'T TUCH THE BORDER");

    printf("Press < p > for pause");
    gotoxy(17,8);
    printf("IN MIDDLE OF GAME, PRESS < Esc > TO EXIT");
    x:
    gotoxy(26,10);
    printf("press < s > to start ");
    gotoxy(26,12);
    printf(" Use SMALL case only");
    gotoxy(34,10);
    if(getch()=='s')
      initgraph(&gd,&gm,"c:\tc\bgi");
    else {
