Could you please add some <code> tags to make your script readable? For example,

<code>
script goes here
</code>

UPDATE: I think the reason you're getting the '256' return is because your system("a.exe"); line is returning an error, not the bit-shifted '3' you are expecting. And I think it's returning an error because system() can't find a.exe, because it's not in your path. Does the return change if you specify system("./a.exe"); , or otherwise explicitly add in the path to the exe?

I'm not on a Windows system, so I can't test your script any more directly.
