Open an existing socket - mode is S for server, C for client, L for Listen (server without accept), R for server with reuse address flag.

Close down a datagram handler.

Send data to a host/port.

Get the ip address of an open socket. (R = remote IP, L = local IP)

Get the port for an open socket. (R = remote port, L = local port)

Set options ([-]L-Linger K-Keep Alive R-Reuse Address N-Don't route [-]D-elay X-Debug - I=#/O=# - internal input output buffer controls T=# TS=# TR=# timout in milliseconds for timeout on send/receive or timeout [S]end,[R]ecieve ).

Get options (A-accepting L-Linger K-Keep Alive R-Reuse Address N-Don't route D-elay X-Debug - I=input buffer O=output buffer T=timeout - '' escapes characters ).

Send data to a host/port wait for returned response.

Setup an named asynchronous handler - when input matches the 'match string' , the code will be invoked with the incoming string in a_message.

An important part of writing any program is handling potential errors properly. You should do the same when writing an Xbasic script, making sure it can recover from some common run-time errors (e.g., when a file is not found, the disk is full, or the table is opened exclusively by another session or user).
