When sending a request to a server, you must also indicate the following:

• The function to be performed. See FUNCTION keyword of IXCSEND.
• A description of the request. See DESCRIPTION keyword of IXCSEND.
• The identity of the target server. See Identifying the target server.
• Server selection criteria. See Server selection criteria.
• Whether a reply is expected. See Using EXPECTREPLY and RESPONSELEVEL.
• The desired level of the response data. See Specify additional response information.
