Request change of direction from sending transaction on an APPC mapped conversation.
ISSUE SIGNAL (APPC) >>-ISSUE SIGNAL--+--------------+--+-------------+------------->< '-CONVID(name)-' '-STATE(cvda)-'
Conditions: INVREQ, NOTALLOC, TERMERR
ISSUE SIGNAL, in a transaction in receive mode, signals to the sending transaction that a mode change is needed. It raises the SIGNAL condition on the next SEND, RECEIVE, or CONVERSE command executed in the sending transaction, and a previously executed HANDLE CONDITION command for this condition can be used either to take some action, or to ignore the request.
For compatibility with earlier releases, SESSION is accepted as a synonym for CONVID. New programs should use CONVID.
If both CONVID and SESSION are omitted, the principal facility is assumed.
Default action: terminate the task abnormally.
Default action: terminate the task abnormally.
A CANCEL TASK request by a user node error program (NEP) may cause TERMERR if the task has an outstanding terminal control request when the node abnormal condition program handles the session error.
Default action: terminate the task abnormally with abend code ATNI.
