I'm trying to use the system() function on a win32 machine to run a DOS command and capture its error code. It seems like the return value is overflowing, though, if it's any greater than 255. I tested with this sample program: 
$num = 256;
$res = system('exit /b $num');
print $res/256;

For values of $num less than 256, it works as expected. Anything higher, and it doesn't. Is this a limitation of win32 Perl? Is there a workaround?

A fair fight is a sign of poor planning.
