CONVERSE communicates on a 3600 logical unit.
The data stream and communication format used between a CICS® application program and a 3614 is determined by the 3614. The application program is therefore device_dependent when handling 3614 communication.
For further information about designing 3614 application programs for CICS, refer to the IBM® 4700/3600/3630 Guide.
If the value specified is less than zero, zero is assumed.
If the length of data exceeds the value specified and the NOTRUNCATE option is not present, the data is truncated to that value and the LENGERR condition occurs. The data area specified in the TOLENGTH option is set to the original length of data.
If the length of data exceeds the value specified and the NOTRUNCATE option is present, CICS retains the remaining data and uses it to satisfy subsequent RECEIVE commands. The data area specified in the TOLENGTH option is set to the length of data returned.
If no argument is coded for MAXLENGTH, CICS defaults to TOLENGTH.
If DATALOCATION(ANY) is associated with the application program, the address of the data can be above or below the 16MB line.
If DATALOCATION(BELOW) is associated with the application program, and the data resides above the 16MB line, the data is copied below the 16MB line, and the address of this copy is returned.
If TASKDATAKEY(USER) is specified for the running task, and storage protection is active, the data returned is in a user-key. If TASKDATAKEY(CICS) is specified and storage protection is active, the data returned is in a CICS-key.
If the length of the data exceeds the value specified, but NOTRUNCATE is omitted, the data is truncated to that value, and the LENGERR condition occurs. When the data is received, the data area is set to the length of the data.
For a description of a safe upper limit, see LENGTH options in CICS commands.
Default action: terminate the task abnormally.
A CANCEL TASK request by a user node error program (NEP) may cause this condition if the task has an outstanding terminal control request active when the node abnormal condition program handles the session error.
Default action: terminate the task abnormally with abend code ATNI.
