Cool. I still wonder which object you are using - you mention both user index and data queue in your post - just curious while looking for work!!

Chuck and Vern,

The QUSRMVUI API returns the entries that were removed from the index effectively giving you a read and delete at the same time.

Multiple programs can access a user index at the same time. The key is
how they access it. You can do a 'destructive' read which removes the
entries when they are read or you can simply read the entries.
Obviously, if entries are removed when read they won't be available
for other programs to access.
What MI instruction or API provides a "destructive read" capability for a
User Index object? There is the by-default destructive-read of messages
read from a Data Queue, and there is an alternate means to effect a non-
destructive-read of messages\entries on a queue. Or was perhaps a private
interface that combines the effects of FNDINXEN and RMVINXEN [or the
equivalent APIs: Retrieve User Index Entries (QUSRTVUI) API and Remove
User Index Entries (QUSRMVUI) API] being described, rather than a specific
method provided by the OS to access the Independent Index?
