Guess what, first program I put in, it was needed. :)  Can't remember what
function it was for now. :)

And that's the part I need to learn. ;)  Reading FP documentation on network
programming and using the libraries didn't help.

I bet there's a lot more good libraries around now.

Yeah, no surprise there.  Only exception would be for DOS software running in a
suitable VM, but I don't reallt want to write DOS software these days.

Yeah makes sense. :)
