In general, do not assume the UNIX/POSIX semantics that you can shift
-the C<$?> left by eight to get the exit value, or that C<$? & 127>

would give you the number of the signal that terminated the program,
or that C<$? & 128> would test true if the program was terminated by a
coredump. Instead, use the POSIX W*() interfaces: for example, use
WIFEXITED($?) an WEXITVALUE($?) to test for a normal exit and the exit
value, and WIFSIGNALED($?) and WTERMSIG($?) for a signal exit and the
-signal. Core dumping is not a portable concept so there's no portable
+signal. Core dumping is not a portable concept, so there's no portable
way to test for that.
Only implemented if ToolServer is installed. (S<Mac OS>)
