The IXLDISC macro allows you to disconnect from a structure. You can disconnect from only one structure at a time. If you wish to disconnect from multiple structures, issue IXLDISC once for each structure.

IXLDISC requires that you provide the connect token (CONTOKEN) that XES returned when the initial connection to the structure was made with IXLCONN. You also must invoke IXLDISC from the same task that issued IXLCONN for the connection. During the rebuild process, if a connection disconnects during rebuild and a rebuild connect is issued from a different task, the subsequent disconnect must be done from the task that did the original connect.

The IXLDISC macro allows you to specify the reason for your disconnection. If you do not specify a reason, the system assumes this is a normal disconnection. You can also communicate information about your disconnection to surviving peer connectors by using the DISCDATA keyword. This eight bytes of data is passed to the event exits of surviving peers when you disconnect.
