Fellow monks,
I promised this update about a week ago or more, but forgot. For this failure, I deeply apologize.
However, I did the testing I promised.
The findings are rather interesting. On a Linux system, $! only returns a 'Bad File Descriptor' message when called immediately after qx(). I tried calling $! empty, and it returned nothing.
Perhaps someone knows how the $! is tied to the handle used to return info from qx() ?
Peace be you, monks.
