Thanks for taking the time to report a problem.  But when reporting
problems please say what version of the program you are using.
Frequently it is found that the program isn't even one of the ones
maintained here!

  tail --version

You have used an incorrect syntax.  The '=' is bogus there.  Use one
of these instead.

  tail -n 10570 mode12.dat > 12
  tail -n10570 mode12.dat > 12
  tail --lines=10570 mode12.dat > 12
