Please make sure that DtaqLen is the same length as DATAQDS. If possible,
make the line before the call to RcvDtaq() look like this:

     DtaqLen = %size(DATAQDS)

And make sure that line of code is called prior to the API, each time the
API is called.  If DtaqLen contains a higher value that the size of
DATAQDS, you'll corrupt memory (which is why I suspect the beginning of
your data queue name is being wiped out.)

The third parameter to this API is an output parameter, set by the API
to say how big a message it returned; the API assumes the receiver
parameter is big enough to receiver any message.  So if you only pass 5
parameters, you have to ensure that the receiver parameter is at least
as long as the maximum size of a message on the data queue.  (This is
the size specified when the data queue was created.)

There is another parameter, I think parameter 12, where you can specify
the length of your receiver parameter.
