The Receive Data Queue (QRCVDTAQ) API receives data from the specified data queue.
When more than one program has a receive pending on a data queue at one time, a data entry sent to the
data queue is received by only one of the programs. The program with the highest run priority receives the
entry. The next entry sent to the queue is given to the job with the next highest priority.
If the data queue was created with the AUTORCL keyword on the Create Data Queue (CRTDTAQ)
command set to *YES, when the queue is empty the storage allocated to the data queue will be reduced to
the storage needed for the initial number of entries defined for the data queue.
Distributed data management (DDM) data queues are supported using this API. This means that you can
