'Seterr' is used to set the error status code variable in the
Subsystem common area.
This variable is examined by the Shell when it regains control
after the execution of a user program;
if the value of the status code is greater than or equal to
1000, then the Shell assumes a fatal error has occurred and
shuts down all currently active shell programs.
