Yikes, yeah I didn't realize that "Global Symbol...." error was due a declaring issue, I've always declared them with 'my' but forgot and should have thought that through more, yaddayadda.. With the undefined subroutine problem, my issue was resolved by adding use Socket; duhhh! So from my understanding, that type of error will come up if you try to call some type of function incorrectly, say I write INET_ATON instead of inet_aton, because perl is case sensitive, right? Orrr, in this case, not 'using' the Socket or a module perhaps? Thanks as always
