Is it possible to browse a non-keyed DQ (not remove entries)
displaying all entries in the DQ?
I did try using PEEK, but after reading the first record, since it
does not remove it since I am using PEEK, the next subsequent read
brought back the same record.
A PEEK is just a request to perform a non-destructive Read\Receive of
the logically "first" or "top" entry\message in the Data Queue (DTAQ)
object [according to the queue ordering definition LIFO, FIFO, keyed].
That is, effectively using the Receive Data Queue (QRCVDTAQ) API with
option "Remove message"=*NO specified; repeated requests against a
static data queue would see the same entry every time. See also:
