Creates a new UDP Socket.
Socket reference numbers are starting at 29000 and counting up for each new socket.
For use with broadcast, we create IPv4 here.


Create a new UDP Socket:

Set Variable [$$sock; Value:MBS("Socket.NewUDPSocket")]

Create a new UDP socket for broadcast and listen on a port:

If [not (GetAsNumber($$sock) > 0)]
    Set Variable [$$sock; Value:MBS("Socket.NewUDPSocket")]
    If [GetAsNumber($$sock) = 0]
        Show Custom Dialog ["Failed to create Socket"; $$sock]
        Exit Script []
    End If
End If
Set Variable [$r; Value:MBS("Socket.Listen"; $$sock; UDP Broadcast::Port)]
Set Field [UDP Broadcast::Send Result]
Set Variable [$r; Value:MBS("Socket.SetDataAvailableHandler"; $$sock; Get(FileName); "ReadMessage")]
Set Variable [$r; Value:MBS("Socket.SetBroadcast"; $$sock; 1)]
Set Variable [$r; Value:MBS("Socket.SetMulticastLoop"; $$sock; 0)]
