ABTSEV (ABORT_SEVERITY) -- Set or display the abort severity level.
usage:  ABTSEV [ -T | -F | -W | -E | -O | -I | -P | -M]


FORMAT

  ABTSEV [options]


  ABTSEV  sets  or shows the severity level at which a shell program will abort.
  The abort severity level is initially set to -ERROR when a Shell  is  created.
  If  any  command  returns  a severity level greater than or equal to the abort
  severity  level,  then  that  shell  program,  and  all  its  ancestors,   are
  immediately terminated.

  The  abort severity level is on a per-Shell basis.  A new level is established
  every time a Shell program or a  new  Shell  is  invoked.    A  Shell  program
  inherits  the abort severity level of the preceding level.  The severity level
  is restored when you exit from the Shell program.

  ABTSEV is an internal shell command.
