Forums Developers perl+mirc version of /exec (under wine)

I have a quick question about this dll, is there anyway to use it asynchronously without a callback? i.e. $exec(-a ipconfig,echo -s )

Would be good if it could do this, if it can already then just ignore this.. Also I've noticed it cannot use commands like ver or dir on windows (I know these are pretty much possible through mIRC anyway)
