 +===== NetConnect =====
  
 +==== Format ====
 +**netconnect** //​server_name//,​ //​port_number//​\\
 +**netconnect** ( //​server_name//,​ //​port_number//​ )\\
 +**netconnect** //​socket_number//,​ //​server_name//,​ //​port_number//​\\
 +**netconnect** ( //​socket_number//,​ //​server_name//,​ //​port_number//​ )
 +
 +==== Description ====
 +Open a network connection (client) to a server. ​ The IP address or host name of a server are specified in the //​server_name//​ argument, and the specific network port number in the //​port_number//​ argument. ​ If //​socket_number//​ is not specified socket number zero (0) will be used.
 +
 +==== Example ====
 +Open two instances of BASIC-256 on a single computer. ​ Paste the "​server"​ code into one and the "​client"​ code into the other. ​ Run the server first and the client second. ​ You can see how the messages are sent back and forth between the two different processes.
