Getting feedback from date and time callable services
You can specify a feedback code
parameter (which is optional) in any date and time callable
service. Specify OMITTED
for this parameter if you do not want the service
to return information about the success or failure of the call.
About this task
However, if you do not specify this parameter and the callable service does not complete successfully, the program will abend.
When you call a date and time callable service and specify OMITTED
for the feedback code, the RETURN-CODE
special register is set to 0 if the service is
successful, but it is not altered if the service is unsuccessful.
If the feedback code is not OMITTED
, the RETURN-CODE
special register is always set to 0 regardless
of whether the service completed successfully.
