This system variable is set following an &APPC RECEIVE_AND_WAIT or &APPC RECEIVE_IMMEDIATE request and indicates the type of data returned by the request.

A value of DATA_COMPLETE indicates that data was returned in the variables supplied.

A value of DATA_TRUNCATED or DATA_INCOMPLETE indicates that data was returned but an error has occurred that caused the data to be truncated.

A value of SEND indicates that no data was returned, but that the remote conversation partner has entered receive state, so the local conversation has entered send state.

A value of CONFIRM, CONFIRM_SEND, or CONFIRM_DEALLOCATE indicates that no data was returned, but that the local conversation should issue an &APPC CONFIRMED request, following which receive, send, or deallocate state is entered respectively.

A value of DEALLOCATE indicates that no data was returned, but that the remote conversation partner issued a DEALLOCATE TYPE=FLUSH, and the local conversation should issue an &APPC DEALLOCATE TYPE=LOCAL to free all conversation resources.
