Reporting Error Message

[Xandy]

I'm listing the error message strings, and roughly matching the error code

Is this how to do error reporting?  Is there a more simple way I don't know about?

I realise I might not need to trap @error inside $error.  I like it this way b/c I have no fear of overwriting @error now; I don't even use it.

Func Send_Connect($address, $port)
    $socket = TCPConnect($address, $port)
    $error = @error
    If $error <> 0 Then
        Local $aError[4] = ["-2 not connected.", _
                            "1 IPAddr is incorrect.", _
                            "2 port is incorrect."]
        $aError[3] = "10060 Connection timed out."
        If $error < 0 Then $error = 0
        If $error > 2 Then $error = 3
        MsgBox(0, "TCP Connect Error", $aError[$error], 0)
        $socket = 0
    EndIf
    Return $socket
EndFunc

... maybe here (https://www.autoitscript.com/forum/topic/194873-wsa-error-to-text/) you can get more details when $error > 2 ...
