Ooops, I boobed on that one.  it should have been;

      getmouse(int *b,int *x,int *y)
      {
        unsigned local_b,local_x,local_y;
  
        _asm mov ax,0003h
        _asm int 33h
        _asm mov local_b,bx
        _asm mov local_x,cx
        _asm mov local_y,dx

        *b = local_b;
        *x = local_x;
        *y = local_y;
      };

For those using their PCs as UNIX machines, I suspect the mouse
routines might not work as they depend on DOS interrupt 33h.  The
DOS interrupt 33h is enabled when a DOS Microsoft Mouse driver
(or similar) has been loaded before your application.
