JS} 4DOS24H2 itself uses interrupt vector 61h to see
  } if it is already installed and can not identify
  } itself in memory if this interrupt is hooked by
  } some TSR after installation of 4DOS24H2.
While this demonstrates that great minds think alike ,  I think
it was idiotic for a system program to use an interrupt that is
reserved for application use.  Jeers to the 4DOS authors.
In any case I've changed {COMMO} to use a method that is guaranteed
not to conflict with anybody.  Next beta.
