system In general, do not assume the UNIX/POSIX semantics that you
can shift $? right by eight to get the exit value, or that

As an optimization, may not call the command shell specified
in $ENV{PERL5SHELL}. "system(1, @args)" spawns an external

process and immediately returns its process designator,

without waiting for it to terminate. Return value may be

used subsequently in "wait" or "waitpid". Failure to
spawn() a subprocess is indicated by setting $? to "255 <<
8". $? is set in a way compatible with Unix (i.e. the
exitstatus of the subprocess is obtained by "$? >> 8", as
described in the documentation). (Win32)
