If you check the system page, you'll see that you (probably) need to use the $?...

$? is set to the return value of system are the same thing. I don't see the point of using a global variable when not needed.

I think you'll looking for $? >> 8.

Yes, or $retVal >> 8.

I don't know why he's getting 256 (Error code 1) instead of 768 (Error code 3), but that's not a Perl issue.

    Later in the day, I began to wonder. If it's the same as the return value from system, when is it ever needed?
