Hi,
    Why is the following code producing a segmentation fault???
I am compiling this code on an Encore Multimax running UMAX 4.3 Unix.
Please send replies to CBUSCH@ub.d.umn.edu.


void cls()
{
   printf("\33[2J");
}

void gotoxy(x,y)
int x,y;
{
   printf("\33[%d;%dH",y,x);
}

void writexy(x,y,s)
{
   printf("\33[%d;%dH%s",y,x,s);
}
   
void start1()
{
   printf("\33[?25l"); /*BTW what does this do with an ANSI terminal?*/
}

void start2()
{
   printf("\33[1;24r"); /*BTW what does this do with an ANSI terminal?*/
}

void end()
{
   printf("\33[?25h"); /*BTW what does this do with an ANSI terminal?*/
}


int main()
{  /*This code is for testing the above for use with terminals*/
   char s[80];
   int x,y;
   start1(); 
  start2();
   do{
      writexy(1,1,"enter x y string:");
      scanf("%d%d%s",&x,&y,s);
      writexy(x,y,s);
   }while(s[0]!='#');


   end();
   return 0; 
}
