The native status returned by the last pipe close, backtick (``) command, successful call to wait() or waitpid(), or from the system() operator. On POSIX-like systems this value can be decoded with the WIFEXITED, WEXITSTATUS, WIFSIGNALED, WTERMSIG, WIFSTOPPED, WSTOPSIG and WIFCONTINUED functions provided by the "Perl interface to IEEE Std 1003.1" (POSIX) in the Perl Library Reference Manual (Volume 3) module.

Under VMS this reflects the actual VMS exit status; i.e. it is the same as $? when the pragma use vmsish 'status' is in effect.
