1 Condition_Handler

  Mn_Fit uses the KUIP condition handler which traps errors and
  `CTRL/C' interrupts. If an error is detected control is returned to
  the `MN_CMD>' level. This means that overflows and any other
  arithmetic errors should not cause the program to exit. It will
  return to the `MN_CMD>' level instead.  WARNING: A `CTRL/C' during
  FORTRAN I/O can cause strange effects, particularly on VMS. To
  suppress the output during an `INDEX' command for example use
  `CTRL/O' and then you can try `CTRL/C' with care.

  If you interrupt with `CTRL/C' inside MINUIT, Mn_Fit sometimes gets
  confused and refuses to start fitting again, so you have to exit and
  restart.
