[PureBasic] Reverse TCP Proxy Server HELP!

@Teddy Rogers (tagging Teddy since I know he has used PureBasic in the past, in fact, thanks to him, I got fevered to learn and code in this nice language.)

Hello everyone, I have been wanting to do a proxy server for a game I have, and so far I've only gotten to work, but it's very broken, I know I'm doing a horrible job handling memory buffers and writing/reading to/from Client to Server and vice-versa, but I have gotten this far on my own, now I need help from you guys as I can't make it work, and I don't know how I could have a better approach at reading/sending data to and from the client and server and vice-versa... I know there could be better ways but I'm just stuck...
