The status returned by the last pipe close, back-tick (C<``>) command,
-or system() operator. Note that this is the status word returned by the
-wait() system call (or else is made up to look like it -- see L<$^S>).
-Thus, the exit value of the subprocess is actually (C<$? E<gt>E<gt> 8>),
-and C<$? & 255> gives which signal, if any, the process died from, and

Inside an C<END> subroutine C<$?> contains the value that is going to be
given to C<exit()>. You can modify C<$?> in an C<END> subroutine to
change the exit status of the script.

-The status returned by the last pipe close, back-tick (C<``>) command, or
-system() operator, in the native system format. On UNIX and UNIX-like
-systems, C<$^S> is a synonym for C<$?>. Elsewhere, C<$^S> can be used to
-determine aspects of child status that are system-specific. Check C<$^O>
-before using this variable. (Mnemonic: System-Specific Subprocess Status.)
+Under VMS, the pragma C<use vmsish 'status'> make C<$?> reflect the
+actual VMS exit status, instead of the default emulation of POSIX
+status.
