abtsev (abort_severity) -- Set or display the abort-severity level
abtsev [-f | -w | -e | -o | -i | -p | -m]
DESCRIPTION
The abtsev command lets you set the severity level at which a shell
command or program aborts. 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.
See the pgm_$set_severity description in the Domain/OS System Call
Reference for further information on severity levels.
Every shell command or program returns a completion status message to its
caller. The message may indicate that the program completed
successfully, or it may inform its caller of a fatal internal error.
Completion status messages vary in their severity. The following
completion status messages appear in order of their severity:
ok Program completed successfully and performed the
requested action.
true Program completed successfully; its purpose was to test a
condition, and the value of that condition was true.
false Program completed successfully; its purpose was to test a
condition, and the value of that condition was false.
warning Program completed successfully and performed the
requested action. However, an unusual (but nonfatal)
condition was detected.
error Program could not perform the requested action because of
an error in the input. The output, however, is sound.
output invalid Program could not perform the requested action because of
a syntactic error in the input, and the output is not
structurally sound.
internal fatal Program detected an internal fatal error and stopped.
The state of the output is unknown.
