Full packets enable software implementation on the mainframe and client sides

I rate it eight out of 10. It's just very powerful tool, very powerful product to use. Nowadays, there are a couple of mainframe companies, using mainframe products, so to be honest, I'm not recommending it. Of course, if you have mainframe and you have do something in the mainframe that’s different.
